Background

The foundation composition can be used for homogenizing skin color and masking flaws, and belongs to basic foundation. Foundation compositions have been developed to date, and have been derived from a wide variety of products for different skin types and different cosmetic effects. In recent years, with the increase of the safety requirements for cosmetics on the market, there has been an increasing demand for creating a foundation suitable for sensitive muscles, and a foundation composition having a repairing and maintaining effect by combining skin care and skin care has been gradually appearing on the market.

In order to solve the problem of skin care, patent CN112603866A provides a radix pseudostellariae skin-nourishing foundation lotion, which contains 0.5% of a combination of centella asiatica extract, polygonum cuspidatum root extract, scutellaria baicalensis root extract, tea leaf extract, glycyrrhiza glabra root extract, chamomile flower extract and rosemary leaf plant extract, 0.5% of a combination of ganoderma sinensis extract, snow lotus extract, ginseng root extract and peony extract and 6-12% of a colorant.

The patent CN111920706A provides a deep repairing foundation liquid and a preparation method thereof, wherein the foundation liquid completely wraps the concealing repairing component foundation liquid in an oil phase by applying a wrapping technology, and the concealing repairing component foundation liquid is fully fused with deep-nursing essence whitening water gel to be combined into a whole. The liquid foundation is of an oil-in-water type, and the powder is suspended in aqueous gel in an oil drop shape. Although the foundation liquid has the effect of deep whitening and repairing, the foundation liquid needs to be uniformly brushed when in use, and the makeup process is complicated. In contrast, the water-in-oil foundation has better fit and faster make-up.

The key point of skin repair is sebum repair, and the powder in the concealer product can absorb grease on the surface of the skin, so that the problem of dry skin can be caused. For persons with a severely compromised barrier, the use of ordinary foundations may result in poor skin condition.

Therefore, it is an urgent technical problem to be solved to develop a foundation composition having a repairing effect to provide the foundation composition with a skin-nourishing effect.

In the powder dispersing process, ordinary homogeneous dispersion cannot disperse the powder to the original particle size, so that the titanium dioxide is larger than the original particle size after dispersion. The titanium dioxide with larger particle size has strong covering power, the titanium dioxide with middle particle size has certain covering power, and the titanium dioxide with small particle size has weak covering power but good conformability.

Further, in the invention, the content of the titanium dioxide can be 12-24%, preferably 12-18%; for example: the content of the titanium dioxide is 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24% and the like. When the content of the titanium dioxide is 12-24%, the concealing effect is excellent.

Further, in the present invention, the concealer component further comprises one or a combination of two or more of a pigment, a dispersant, a emollient grease, an elastomer, silica, and a film former; the foundation composition comprises, by 100% of the total mass of the foundation composition, 0.1% -1.5% of pigment, 0.3% -1.5% of dispersant, 10% -28.8% of emollient oil, 2% -5% of elastomer and 2% -5% of film-forming agent; the content of the silica is 2% -5%.

Whether the makeup is applied or not is a standard for evaluating the quality of the makeup base, the addition of the dispersing agent is beneficial to the dispersion of the powder components, and the powder can be better applied by using the dispersing agent. The content of the dispersant is 0.3 to 1.5% based on 100% by mass of the foundation composition, for example: the content of the dispersant is 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, etc. When the content of the dispersing agent is 0.3-1.5%, the skin feel is light, and the powder is uniformly dispersed and has good fitting property.

Specifically, the dispersing agent comprises one or two of polyhydroxystearic acid and polyglycerol-3 diisostearate.

In the present invention, the addition of the elastomer can bring about an effect of concealing pores. The content of the elastomer is 2% to 5% based on 100% of the total mass of the foundation composition, for example: the content of the elastomer is 2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5%, 3.8%, 4%, 4.2%, 4.5%, 4.8%, etc.

Specifically, the elastomer comprises one or more of polydimethylsiloxane/vinyl polydimethylsiloxane cross-linked polymer, polysiloxane-11 and HDI/trihydroxyhexyllactone cross-linked polymer.

In the invention, the makeup durability after makeup is also a key concern, and the addition of the film forming agent is beneficial to the makeup-holding effect after makeup. The content of the film forming agent is 2% -5% by the total mass of the foundation composition as 100%, for example: the content of the film forming agent is 2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5%, 3.8%, 4%, 4.2%, 4.5%, 4.8% and the like.

Specifically, the film forming agent comprises one or the combination of more than two of trimethylsiloxy silicate, stearic acid citrate and tri (octyldodecanol) citrate.

In the present invention, the color of the foundation composition is adjusted by using a pigment to make the foundation composition closer to skin color. The content of the pigment is 0.1 to 1.5% based on 100% of the total mass of the foundation composition, for example: the content of the pigment is 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, etc.

Specifically, the pigment comprises one or the combination of more than two of iron yellow, iron red and iron black.

Further, the invention improves the skin feel of the powder-liquid composition by using the emollient oil and fat and can play a role in moisturizing. The content of the emollient oil is 10-28.8% by total mass of the foundation composition, such as: the content of the emollient oil is 12%, 15%, 18%, 20%, 22%, 25%, 28%, etc.

Specifically, in the present invention, the emollient oil comprises one or a combination of two or more of dioctyl carbonate, isododecane, polydimethylsiloxane, phenyl trimethicone, hydrogenated polyisobutene, C12-15 alcohol benzoate, glycerol tri (ethyl hexanoate), dioctyl carbonate, and diisostearyl malate.

Further, the concealer component of the present invention may also comprise silica, which helps to increase the slip and remove the oily feel by making it easier to push away when applying make-up. In the present invention, the silica content is 2 to 5%, for example: the silica content is 2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5%, 3.8%, 4%, 4.2%, 4.5%, 4.8%, etc.

Repairing component

The foundation composition has a certain repairing effect while having hiding power by using the repairing component. Specifically, in the present invention, the content of the repair component is 0.91% to 3.6%, preferably 1% to 3%, based on 100% by mass of the total foundation composition; for example: the content of the repairing component is 1%, 1.2%, 1.5%, 1.8%, 2%, 2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5% and the like. When the repairing component of the present invention is less than 0.91%, the user does not feel the repairing effect; when the content of the repairing component is higher than 3.6%, adverse reactions such as heavy skin feel, acne and irritation exist.

In the present invention, the repair component may include one or a combination of two or more of essential oils, ceramides, phytosterol canola oil glyceride; wherein the content of the essential oil can be 0.4-1.4%, the content of the ceramide can be 0.01-0.5%, and the content of the phytosterol canola oil glyceride can be 0.5-1.7% based on the total mass of the foundation composition as 100%; preferably, the essential oil comprises one or more of lavender essential oil, tea tree essential oil and sweet orange essential oil.

In the invention, the essential oil can improve oily skin, remove cell cutin, maintain skin elasticity and effectively improve circulatory disturbance. In addition, the essential oil can promote sleep, prevent wrinkle, eliminate dark eye circles and help to lighten color spots. Specifically, in the invention, the lavender oil and the tea tree essential oil have strong antibacterial and anti-inflammatory effects, and have a repairing effect on damaged skin. The sweet orange essential oil has antibacterial effect and antioxidant effect, and can be used for caring dry and aging skin.

Further, in the invention, the content of the essential oil is 0.4-1.4% by taking the total mass of the foundation composition as 100%; for example: the content of the essential oil is 0.45%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.35% and the like. When the content of the essential oil is 0.4-1.4%, the essential oil can play a role in controlling oil and promoting blood circulation. And can achieve the effect of skin care after long-term use.

The inventor finds that the combination of the lavender essential oil, the tea tree essential oil and the sweet orange essential oil has a synergistic effect and can further play a repairing role. Wherein, the content of the lavender essential oil is 0.3% -1%, such as: the content of the lavender essential oil is 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% and the like; the content of the tea tree essential oil is 0.05-0.2%; for example: the content of the tea tree essential oil is 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18% and the like; the content of the sweet orange essential oil is 0.05% -0.2%; the content of the sweet orange essential oil is 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.11%, 0.12%, 0.13%, 0.14%, 0.15%, 0.16%, 0.17%, 0.18% and the like.

Further, ceramide is a main component constituting the skin stratum corneum lipid, and the invention helps repair the skin barrier by properly adding some ceramide, thereby making the skin soft and glossy. Ceramide not only can resist external stimulation, but also can thicken the horny layer, improve the tolerance of the whole skin, avoid sensitivity and repair red blood filaments, and is an excellent barrier repair component.

Further, in the present invention, the ceramide content is 0.01% to 0.5% based on 100% by mass of the total foundation composition; for example: the content of the ceramide is 0.03%, 0.05%, 0.08%, 0.1%, 0.12%, 0.15%, 0.18%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45% and the like. When the content of the ceramide is 0.01-0.5%, the ceramide is beneficial to repairing skin barriers, the cost is not too high, and the effect is better after long-term use.

In addition, the phytosterol canola glycerides are a synthetic product of the glycerides of canola and phytosterols, and also have the effect of forming a sebum membrane and promoting ceramide secretion from the skin.

Preferably, in the present invention, the phytosterol canola oil glyceride is 0.5-1.7%; for example: the content of the phytosterol canola oil glyceride is 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6% and the like. When the content of the phytosterol canola oil glyceride is 0.5-1.7%, the skin feeling is not heavy, and the repairing effect is excellent.

Moisturizing component

The foundation composition also has moisturizing effect by properly adding some moisturizing components. In the present invention, the moisture-retaining component is contained in an amount of 3% to 10%, preferably 4% to 9%, for example: the content of the moisture-keeping component is 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5% and the like. If the content of the moisturizing component is less than 3%, the moisture feeling after makeup is reduced, and the phenomenon of drying and peeling is easy to occur after makeup; if the moisture-retaining component content of the present invention is more than 10%, the cosmetic composition does not dry quickly.

Specifically, the moisturizing component of the present invention comprises a polyol, hyaluronic acid or a salt thereof, and a ceramide. The moisturizing component can effectively increase the moisture content of the skin epidermis, can achieve deep moisturizing substantially, and can have excellent moisturizing effect when applied to the foundation composition of the present invention.

The polyols of the present invention are relatively low molecular weight polyols. The polyhydric alcohol not only can form a layer of compact protective film on the surface of the skin to reduce the loss of moisture, but also can promote the foundation composition of the invention to absorb moisture from the environment, supplement the moisture to the skin and increase the moisture content on the surface of the skin.

Further, in the present invention, the polyol includes: one or more of glycerol, 1, 4-butanediol, 1, 3-butanediol, pentanediol, 1, 2-propanediol, 1, 3-propanediol, dipropylene glycol, and methyl propanediol. Preferably, the present invention may use one or a combination of two or more of glycerin, 1, 3-butanediol, and pentanediol as the polyol, and when glycerin and 1, 3-butanediol are used, the effect of the foundation composition of the present invention can be exhibited to the maximum extent, and the water content on the skin surface can be effectively increased. When the pentanediol is used, the preservative synergistic effect can be achieved while moisture is preserved. In the present invention, when glycerin, pentanediol, and 1, 3-butanediol are preferably used as the polyhydric alcohol, the effect of the foundation composition of the present invention can be exhibited to the maximum extent, the water content of the skin surface can be effectively increased, and the effects of preservation and synergy can be achieved.

Further, in the present invention, when the content of the polyol is too low, the effect of increasing the water content of the skin surface cannot be exerted, and when the content of the polyol is too high, the effect of increasing the water content of the skin surface is caused to be too low, which affects the skin feel and the cost of the product. Specifically, the polyol content is 2.88% to 8.8%, for example: the content of the polyhydric alcohol is 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8.5% and the like.

Hyaluronic acid, also known as hyaluronic acid, is an acidic mucopolysaccharide. It is an important basic substance for skin tenderness, is a component of human body, has a special water-retaining action, has a weight which is 100 times higher than that of the skin tenderness, is a substance which is found to have the best moisture-retaining property in nature at present, and is called as an ideal natural moisture-retaining factor. It can improve skin nutrition metabolism, make skin tender and smooth, remove wrinkle, increase elasticity, and prevent aging, and is good transdermal absorption promoter while keeping moisture. The nutrient can be used together with other nutrient components to achieve the more ideal effect of promoting nutrient absorption.

In the invention, the hyaluronic acid or the salt thereof can be sodium hyaluronate with large molecular weight or small molecular weight; specifically, the weight average molecular weight of the hyaluronic acid or the salt thereof is less than 180 kilodaltons, and preferably, the weight average molecular weight of the high molecular weight sodium hyaluronate is 100 kilodaltons to 180 kilodaltons, and the weight average molecular weight of the low molecular weight sodium hyaluronate is 5 kilodaltons to 1 kilodaltons.

Generally, the hyaluronic acid salt is usually used in the form of its SODIUM salt, i.e. SODIUM HYALURONATE (SH). The sodium hyaluronate is extracted from rooster comb, or prepared by fermentation of lactococcus lactis, and is white or white-like granule or powder, and has no odor, nitrogen content of 2.8-4.0% and glucuronic acid content of 37.0-51.0% when dried.

However, hyaluronic acid or its salt has a large molecular structure, and is likely to aggregate after being applied to the skin; in addition, hyaluronic acid or its salt has many hydroxyl groups, and adhesion to the skin surface is mainly due to the hydrogen bonding force of the hydroxyl groups, but when the hydroxyl groups do not absorb moisture to the outside, the moisture content of the epidermis cannot be increased. The inventors of the present invention have found that the function of hyaluronic acid or a salt thereof can be further promoted in the presence of a polyhydric alcohol and a ceramide, and that moisture can penetrate into the epidermis of the skin, whereby the moisture content of the epidermis of the skin can be effectively increased, and deep moisturizing can be achieved essentially.

Further, in the present invention, when the content of hyaluronic acid or a salt thereof is too low, the moisture content of the skin epidermis cannot be increased; when the content of hyaluronic acid or a salt thereof is too high, excessive consistency is caused, which is unfavorable for skin absorption. Specifically, the hyaluronic acid or a salt thereof is added in an amount of 0.02% to 0.2%, for example: the content of the hyaluronic acid or the salt thereof is 0.04%, 0.06%, 0.08%, 0.1%, 0.12%, 0.14%, 0.16%, 0.18%, etc.

In the present invention, ceramide is also called glycolipid, phytosphingosine. The ceramide is prepared by screening high-yield strains from candida, converting the strains into the ceramide by using olive oil nutrient substances in the growth and metabolism processes of thalli by adjusting the growth and fermentation conditions of the yeasts and providing certain nutrient substances, is easy to permeate into the intercellular spaces of the horny layer of the skin, maintains the moisture of the skin, and has the effects of moisturizing, moistening the skin and repairing the skin barrier.

The ceramide of the invention is formed by the sugar linkage of fatty acid, mannose and erythrose. The unique structure makes it easy to penetrate into the corneocytes and fuse with the original outer cytoplasm to form a liquid crystal layer. Can be used for keeping moisture and keeping skin moisture. The ceramide has lipophilic and hydrophilic groups, is an amphiphilic molecule, and is helpful for spreading hyaluronic acid on the surface of skin to achieve the effect of moisturizing if being combined with sodium hyaluronate.

The inventors of the present invention have found that the moisturizing function of polyhydric alcohol and hyaluronic acid or a salt thereof can be further promoted in the presence of a ceramide, and the water content of the skin epidermis can be effectively increased. It can promote the humectant to permeate into the horny cells, and achieve the moisturizing effect by locking the humectant.

Further, in the present invention, when the amount of the ceramide added is too low, the moisture content of the skin epidermis cannot be increased; when the amount of the ceramide added is too high, no more excellent effect is obtained, and the cost is also high. Specifically, the amount of the ceramide of the present invention added is 0.1% to 1% based on 100% of the total mass of the foundation composition, for example: the content of the ceramide is 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 0.55%, 0.6%, 0.65%, 0.7%, 0.75%, 0.8%, 0.85%, 0.9%, 0.95%, etc.

Performance testing

1. Evaluation of repairing Effect

Using comparative examples 1 to 3 and examples 1 to 3 as test samples, 14 groups of 10 female subjects each having a self-rated dry sensitive muscle of 20 to 30 years old were selected and tested, and about 0.3g of the test sample was applied to the face each day and made up with a makeup egg. The subjects' sensations after 4 weeks of use were tested in the form of a questionnaire. The skin condition was 10 points, the skin dryness condition was improved to 10 points, and the skin trouble was not improved to 0 points, and the results are shown in table 5.

TABLE 5 evaluation of repairing Effect

As can be seen from the experimental results of table 5, most of the subjects considered that the use of the foundation solution prepared in comparative example 3 could not improve the state of skin dryness. In the foundation solutions prepared in examples 4 to 8, some subjects considered their skin dryness-sensitive state to be somewhat alleviated, and others considered to be ineffective. The subjects who used the liquid foundation prepared in the remaining examples considered the improvement in their own skin condition to be significant.

2. Evaluation of soothing Effect

With comparative examples 1 to 3 and examples 1 to 13 as test samples, 14 groups of 20 female subjects with a self-evaluation of dry sensitive muscles between 20 and 30 years old each were selected for the test. About 0.3g of the powder is taken and smeared on the face, and the makeup is lightly patted by a makeup egg. Whether the subjects have irritation, dryness, itching and the like within 8 hours after use is collected in a questionnaire form. The results are shown in Table 6.
