Technical Field

The application relates to the field of facial cleansers, in particular to a sensitive muscle amino acid mild and clear facial cleanser and a preparation method thereof.

Background

The facial cleanser is also called as face cleanser, is used for removing dirt on the surface of facial skin, keeping the skin fresh and comfortable, and helping to keep the normal physiological function of the skin, and is usually used as the first step in a skin care link.

At present, various face cleansers exist on the market, and the face cleansers mainly comprise soap base system face cleansers, amino acid face cleansers, emulsified face cleansers and other surfactant face cleansers. The other surfactants are generally sulfuric acid surfactants, have abundant foams and strong dirt-removing power, but have strong irritation. The emulsified face cleanser basically has no bubbles, and has poor cleaning effect, so the cleaning effect cannot be achieved. The soap-based facial cleanser has abundant foam, strong cleaning power and high pH value, can cause tight feeling or dry feeling to the skin after being used, is easy to damage the skin, and is not suitable for sensitive muscles.

The pH value of the amino acid facial cleanser is similar to that of human skin, and the nature of the amino acid facial cleanser is mild. However, most of the commercial amino acid facial cleansers in the market have still to be improved because the cleansing power of the facial cleanser is generally weakened to make the products milder.

Disclosure of Invention

In order to improve the cleaning power of the amino acid facial cleanser, the application provides the sensitive muscle amino acid mild and clear facial cleanser and the preparation method thereof.

In a first aspect, the application provides a mild and clear sensitive sarcosine facial cleanser, which adopts the following technical scheme: the mild and clear sensitive muscle amino acid facial cleanser comprises the following raw materials in percentage by mass:

thickening agent: 0.1% -0.5%;

allantoin: 0.1% -0.5%;

disodium EDTA: 0.05 to 0.1 percent;

humectant: 5% -20%;

disodium lauroyl glutamate surfactant: 5% -15%;

PEG-120 methyl glucose dioleate: 0.5% -2%;

sodium chloride: 1% -5%;

sodium lauroyl sarcosinate surfactant: 5% -20%;

cocamide DEA surfactant: 1% -5%;

cocamidopropyl betaine surfactant: 2% -10%;

sodium methyl lauroyl taurate surfactant: 1% -10%;

disodium lauryl sulfosuccinate surfactant: 30% -50%;

preservative: 0.4% -1%;

soapberry extract: 0.1% -2%;

other auxiliary agents: 0.0% -0.5%;

supplementing deionized water to 100%;

the other auxiliary agents are one or a mixture of a plurality of essences, potassium chloride and sodium citrate.

By adopting the technical scheme, the main component of the soapberry extract is soapberry saponin which is used as a natural nonionic surfactant, has the effects of coordinating cleaning and foaming, well sterilizing and diminishing inflammation, reducing irritation of the facial cleanser, whitening and relieving itching, enabling the skin to be fine, smooth and elastic and the like.

By compounding the soapberry saponin, the disodium lauryl sulfosuccinate and the disodium lauroyl glutamate, the dirt-removing capacity of the facial cleanser can be further enhanced, and the irritation of the facial cleanser can be further reduced. Mainly because the sapindoside increases the distance between the hydrophilic groups of disodium lauryl sulfosuccinate and disodium lauroyl glutamate, weakens electrostatic repulsion force, makes the micelle more stable, so that the dirt-removing capacity and the irritation are influenced, the stability of the facial cleanser is enhanced, and the better experience is improved for users.

When the facial cleanser is used, the water for wetting the face is emulsified with the facial cleanser for the first time, and the facial cleanser generates rich and fine foam. The fine foam contacts with the surface of the skin, and the redundant grease in the skin and pores is emulsified with the foam for the second time. Because the soapnut saponin, the disodium lauryl sulfosuccinate and the disodium lauroyl glutamate are matched to form a more stable micelle, the redundant grease firstly reacts with the outer layer of the micelle, and continuously reacts with a place close to the outermost layer after the reaction of the outermost layer is finished, so that the emulsifying time is prolonged, and the cleaning capability to the skin is improved.

In addition, since the cleanser is already emulsified with water for the first time, the second emulsification capacity is weaker than that of the first time, and even if two emulsification processes occur, the skin is not excessively cleaned. After the first emulsification, the redundant grease on the surface of the skin is more easily contacted with the abundant foam of the face cleaning cream, and the second emulsification is more fully carried out.

After the face cleaning cream fully reacts with water and oil on the skin and generates a large amount of plump and fine foam, a user washes the foam by using clear water, redundant grease and the foam leave the skin along with water flow, and the skin of the user has a pleasant feeling of dryness, non-greasiness and non-tightness. Meanwhile, the facial cleanser is mild, after the face is washed, the face feels weak in irritation, and a good moisturizing effect is achieved.

Performance test

1. Sensory evaluation was used: 20 female sensitive muscle volunteers of 20 to 35 were recruited and numbered, and the volunteers washed their faces for 7 consecutive days using the same method for the face cleansers prepared in examples 1 to 12 and comparative examples 1 to 4 and two commercially available face cleansers. Putting 1g of face cleanser in the palm, slightly wetting and lightly kneading with clear water, beating out abundant foam, finely kneading to clean the face, and cleaning with clear water. In this test, 4 evaluation items were set, and specific standards and items were as shown in table 4.

TABLE 4

2. And (3) detecting the common performance: the condition, stability and pH of the facial cleansers prepared in examples 1-12 and comparative examples 1-4 and two commercially available facial cleansers were tested according to GB/T29680-2013 facial cleanser and facial cleanser.

3. Physical and chemical data detection: the face cleansers prepared in examples 1 to 12 and comparative examples 1 to 4 and two commercially available face cleansers were examined to determine viscosity and foaming amount.

The viscosity detection method comprises the following steps: the viscosity of the milk is detected by using an NDJ-5S digital viscometer (Shanghai balance instrument and meter factory), a power supply is plugged, a switch is turned on, the horizontal temperature of the instrument is adjusted to be 25 ℃ at room temperature, a selected 4# rotor is screwed into a connecting screw rod, a lifting platform is rotated to adjust the height of the plane of the facial cleanser in a beaker, the plane of the facial cleanser is immersed to the scale line of the rotor, a rotating speed of 6r/min is selected, a measuring button is pressed, and the reading is recorded after the reading is stable.

The foam amount detection method comprises the following steps: the foam amount of the facial cleanser is detected by using a Roche foam meter, and the method comprises the following steps:

(1)1500mg/kg hard water preparation: 0.37g of anhydrous magnesium sulfate and 0.5g of anhydrous calcium chloride were weighed and sufficiently dissolved in 500ml of deionized water for use.

(2) Preparation of the tested face wash solution: the face cream was weighed out into 1.25g in a 500ml beaker, added with 450ml of deionized water and 50ml of hard water, stirred and dissolved uniformly with a glass rod, and heated to 40. + -. 1 ℃ in a HH-2 digital display constant temperature water bath (Australian instruments, Inc., Hezhou) for use.

(3) An HH-501 super constant-temperature water tank (Australian instruments Co., Ltd., Changzhou) is preheated to 40 +/-1 ℃, a rubber hose is connected to establish circulating reflux water, and the circulating reflux water flows in and out from the rubber hose, so that a Roche foamer is kept at a constant temperature of 40 ℃.

(4) A portion of the tested facial cleanser solution was aspirated through a 200ml dosing funnel and rinsed down the tube wall of the Roche foamer.

(5) Taking the detected face cleanser solution, putting the detected face cleanser solution into the bottom of a Roche foam instrument, aligning the standard scale to 50ml, sucking 200ml of the detected liquid by using a 200ml quantitative funnel, fixing the central position of the funnel, immediately recording the foam height 4 after the detected face cleanser solution is put, and detecting the cleaning and deoiling effect: the skin oil content of the test areas on the forehead before and after use of the facial cleansers prepared in examples 1 to 12 and comparative examples 1 to 4 and the two commercial facial cleansers were tested using a laboratory professional skin oil tester sebumeter sm815 (Courage + khazakaelectronics gmbh, germany).

The degreasing capability of the face cleanser is (A-B)/Ax100%

In the formula:

a, the oil content of the skin before the facial cleanser is used;

b, the oil content of the skin of the facial cleanser after use.

See tables 5-8 for test data for tests 1-4.

TABLE 5

As can be seen from the comparison of the test data of examples 1-3 and comparative examples 1-4 and two types of commercially available facial cleansers in Table 5, the facial cleansers prepared in examples 1-3 have richer foams, better cleaning ability, better post-wash fineness than those of comparative examples 1-4, and the user has less dry, tight and allergic face after using the facial cleansers of examples 1-3. In general, the facial cleansers of examples 1 to 3 provide a user with a better experience. Although the commercial facial cleansers do not have the same lather, cleansing power, and post-wash moisturization as examples 1-3, the commercial facial cleansers provide the user with a good experience in all aspects. On the whole, the commercial face cleansers are superior to comparative examples 1-4, and inferior to examples 1-3.

The facial cleansers of examples 4 to 9 are slightly superior to the facial cleansers of examples 1 to 3 in all aspects, and it is explained that the amounts of sodium lauroyl sarcosinate, disodium lauroyl glutamate surfactant, disodium lauryl sulfosuccinate, sodium chloride and soapberry extract are further limited to be advantageous for improving the quality of the facial cleansers.

The performances of the face cleansers of examples 10 to 12 are similar to those of examples 1 to 3 in all respects, which shows that the selection of the preservative has little influence on the foam richness, the cleansing power, the after-wash moisturizing degree, and the like.

TABLE 6

As shown by comparing the test data of examples 1 to 12 with those of comparative examples 1 to 4 and two types of commercially available face cleansers in Table 6, the face cleansers prepared in examples 1 to 12 are better in appearance than those of comparative examples 1 to 4, and users feel better with the face cleansers prepared in examples 1 to 12. The examples 1 to 12 are clearly superior to the comparative examples 1 to 4 in terms of stability. In terms of pH, examples 1-12 and both commercial facial cleansers are weakly acidic, and comparative examples 1-4 are neutral, indicating that examples 1-12 are milder and provide a good user experience.

TABLE 8

As shown by comparing the test data of examples 1 to 12 with comparative examples 1 to 4 and two types of commercial facial cleansers in tables 7 and 8, the viscosity of examples 1 to 12 is higher than that of comparative examples 1 to 4, and examples 6 to 7 and 12 are the highest among the experimental groups, so that the appropriate viscosity can also provide a good experience for the user. Examples 1 to 12 all had good foamability in terms of the amount of foam, with the best of examples 6 to 7, 12 and the foamability of comparative examples 1 to 4 being weaker. The cleansing, especially the oil removing ability of the cleansing cream of examples 1 to 12 is better than that of comparative examples 1 to 4, and the cleansing cream of examples 1 to 12 has good cleansing effect while being mild and non-irritating.
