Technical Field

The invention relates to the field of cosmetics, in particular to a moisturizing and repairing hand mask.

Background

The hands are exposed and often contacted with various substances, such as dryness, friction and trauma, and are easily subjected to lipid dissolving action of acid, alkali and organic solvents. In life and labor, the skin is easily chapped by local action.

The moisture content in the horny layer is insufficient to cause the skin to be dry, and the moisturizing agent can increase the moisture content of the epidermis and restore the barrier function of the skin, so that the moisturizing agent is one of the necessary components in the cosmetics. At present, the commonly used cosmetic moisturizing agents comprise glycerin, propylene glycol, butylene glycol, polyethylene glycol, sorbitol, xylitol, sodium lactate, urea and the like, although the types of the cosmetic moisturizing agents are many, the moisturizing effect is limited, and the ideal moisturizing effect cannot be achieved.

Urea is a good moisturizing ingredient, and human skin contains a large amount of urea which is mainly present in the horny layer of the skin and is a main ingredient of Natural Moisturizing Factors (NMF) of the skin. The urea has excellent skin care effect, is added into a plurality of skin care products, and is widely applied in the field of medicines.

However, most of the cosmetics on the market use water as a matrix, and urea is not easy to exist stably in water and is easy to decompose into carbon dioxide and ammonia, so that a product system is unstable, the pH value is increased, skin irritation is caused, the appearance is yellowed, and pungent ammonia odor is generated, and the use of the cosmetics is finally influenced.

At present, aiming at the problem that urea is easy to decompose, the problem is not solved fundamentally because the color change phenomenon of the cosmetics sold in the market is only covered by adding yellow pigment and the bad smell is covered by adding essence.

Disclosure of Invention

The technical problem to be solved by the invention is to provide the urea-containing hand mask which is not easy to discolor after being stored for a long time and has good moisturizing and repairing effects.

The specific technical scheme of the invention is as follows:

the moisturizing and repairing hand mask comprises the following components in percentage by mass: 1-10% of urea and 0.2-2% of triethyl citrate.

In one embodiment, the moisturizing hand repairing film comprises the following components in percentage by mass: 5% of urea and 1% of triethyl citrate.

The moisturizing hand repairing film also can comprise a thickening agent, wherein the thickening agent can be composed of acrylic acid (ester)/isodecyl vinyl ester cross-linked polymer, polyacrylate cross-linked polymer-6 and hydroxyethyl cellulose; the addition amount of the acrylic acid (ester)/vinyl isodecanoate crosslinked polymer in the moisturizing and repairing hand membrane can be 0.1-0.3wt%, the addition amount of the polyacrylate crosslinked polymer-6 can be 0.2-0.4wt%, and the addition amount of the hydroxyethyl cellulose can be 0.05-0.3 wt%.

The moisturizing hand repairing film also comprises a humectant which can be composed of glycerin, allantoin, sodium hyaluronate, polyglutamic acid and PEG/PPG-17/6 copolymer; the addition amount of glycerol in the moisturizing and repairing hand membrane can be 5-8%, the addition amount of allantoin can be 0.1-0.3%, the addition amount of sodium hyaluronate can be 0.01-0.1%, the addition amount of polyglutamic acid can be 0.01-0.1%, and the addition amount of PEG/PPG-17/6 copolymer can be 0.1-1.5%.

The moisturizing and repairing hand mask can also comprise repairing active ingredients, wherein the repairing active ingredients comprise an extract of bark of Pinus maritima (Pinus PINASTER), an extract of Parthenia italica (Helichrysum italicium), and an extract of leaves of Agave TEQUILANA (Agave TEQUILANA); the moisture keeping hand repairing hand mask may contain 0.1-1% of Pinus maritima (Pinus PINASTER) bark extract, 0.1-0.5% of Parthenium ITALICUM (Helichrysum ITALICUM) extract, and 0.1-1% of Agave TEQUILANA (Agave TEQUILANA) leaf extract.

The moisturizing hand repairing film can also comprise a preservative. The preservative may be Euxyl PE9010, and the addition amount thereof may be 0.5-1 wt%. The Euxyl PE9010 is a liquid preservative in Shumei in Germany, and comprises phenoxyethanol and ethylhexyl glycerol.

The moisturizing and repairing hand mask disclosed by the invention also can comprise 0.01-0.05wt% of EDTA disodium, 0.01-0.2wt% of sodium hydroxide, 0.01-0.1wt% of essence, 0.1-0.4wt% of panthenol and 0.3-0.8wt% of p-hydroxyacetophenone.

The technical scheme provided by the embodiment of the invention has the following beneficial effects:

(1) according to the invention, the triethyl citrate is selected to stabilize the urea, so that the problems of easy color change and ammonia odor after the urea is added into the formula of the hand mask are solved;

(2) the invention selects panthenol, PINUS maritima (Pinus PINASTER) bark extract, flos chrysanthemi italicum (Helichrysumitaccum) extract and AGAVE TEQUILANA (Agave TEQUILANA) leaf extract as repairing active ingredients, and repairs the dermis layer, the basement membrane and the cutin barrier of the skin in a triple way, thereby having good effects of improving the moisture content of the skin and reducing the moisture loss of the skin. Experiments prove that the prepared hand mask can effectively reduce transepidermal water loss (TWEL) and effectively repair damaged skin barriers.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below, but the embodiments of the present invention are not limited thereto, and process parameters or conditions not particularly noted may be performed with reference to conventional techniques.

The Pinus maritima is a plant of Pinus of Pinaceae, and is naturally distributed in mediterranean coast and native place. The Mediterranean pine is a strong and resistant plant and grows in drought, insolation and salt-rich areas. This harsh environment is where other plants cannot grow. The bark extract of Pinus maritima contains procyanidin, and has strong antioxidant and free radical scavenging effects. Suitable maritime pine (Pinus PINASTER) bark extracts may include Pantrofina Skin 360 (from Res Pharma Industriale, USA).

The Italian parietes, which is related to the present invention, generally grows in the wind of sand dunes at seaside and has unique and strong fragrance, and is also called "permanent flowers", "immortal herbs", "Helichrysum ITALICUM", "Curry herbs", etc. Italian parietes extracts are rich in flavonoid and other ingredients, and can promote the release of β -endorphin to achieve a soothing effect and reduce the skin inflammatory response.

The extract of leaves of AGAVE tequilensis (AGAVE TEQUILANA) of the present invention has the effects of balancing the skin microbiome, reestablishing the microbial barrier protection, and protecting against the damaging effects of preservatives. The suitable extract of leaves of tequila (agave et equinulana) may comprise octopein (from seting, france) or blue silk (from setic, france).

D-panthenol, also called vitamin B5, is converted into pantothenic acid after being absorbed by skin after long-term use, and the synthesized coenzyme A by tissues can be present in the tissues and is necessary for metabolism of cell substances, so that the long-term use of vitamin B can improve the cell vitality, repair damaged skin and enhance the barrier function of the skin, thereby obviously reducing TEWL. As a moisturizer, it can improve stratum corneum hydration, reduce TEWL, reduce skin roughness and soothe irritated skin. In addition, the wound healing agent can activate fibroblast proliferation and accelerate epithelial cell regeneration, so that the wound can be healed.
