AI Technical Summary
In the prior art, the release of the active ingredient N-[4-(2,4-dihydroxyphenyl)-1,3-thiazolyl-2-yl]-2-methylpropionamide (isobutyramidothiazolyl resorcinol) from the substrate mask is low, resulting in poor cosmetic effects.
A cosmetic composition containing isobutyramide thiazolyl resorcinol is formed by adding polar oils, fatty alcohols, glycols, emulsifiers and preservatives, using a cellulose fiber-based substrate, particularly lyocell or viscose fiber, with an average pore size greater than 15 µm, a thickness between 0.6 mm and 1.03 mm, and an impregnation degree between 2.1 and 4.0.
It improves the bioavailability of active ingredients and the effects of cosmetics, especially the whitening effect of Peptide Amectin.

Abstract
Description
Technical Field
[0001] This invention relates to a cosmetic product comprising a cellulose fiber-based substrate, said substrate being impregnated with a substance containing… N Cosmetic compositions of -[4-(2,4-dihydroxyphenyl)-1,3-thiazolyl-2-yl]-2-methylpropionamide (INCI: isobutyramidothiazolyl resorcinol). Background Technology
[0002] Over the past few years, the production of cosmetic products has shown an upward trend. This is mainly due to consumers' increasing awareness of hygiene and health.
[0003] A face mask represents a special form of cosmetic. In this special form of facial cleansing and care, a relatively viscous paste is typically applied to the skin in a concentrated form and left to act on the skin for an extended period of time.
[0004] Another form of face mask can use a base material and non-woven fabric impregnated with cosmetic liquid. Many consumers prefer this form because it is easier to use.
[0005] One drawback of existing technologies is the relatively low release of active ingredients from substrate-based masks. Many active ingredients are immobilized on the surface of the substrate material, either within its porous system or through absorption. For this reason, the efficacy of active ingredient-based cosmetics is very low.
[0006] For active ingredients N This phenomenon is particularly observed with -[4-(2,4-dihydroxyphenyl)-1,3-thiazolyl-2-yl]-2-methylpropionamide (INCI: isobutyramidothiazolylresorcinol, also known by the trade name Thiamidol). This compound is relatively polar and exhibits good solubility in water and ethanol. For this reason, it is capable of interacting with polar surfaces via hydrogen bonds. On the other hand, Thiamidol is one of the world's most popular skin-whitening ingredients. Summary of the Invention
[0007] Therefore, the object of this invention is to eliminate or significantly reduce the disadvantages of the prior art. The object of this invention is to manufacture a substrate-based face mask containing peptide Amidato as an active ingredient, which has high cosmetic applicability.

[0016] According to an advantageous embodiment of the invention, the cosmetic product is characterized in that the impregnation degree, i.e., the weight ratio of the cosmetic formulation to the substrate, is between 2.1 and 4.0. Preferably, it is between 2.4 and 3.7, and particularly preferably, it is between 2.7 and 3.4.

N -[4-(2,4-dihydroxyphenyl)-1,3-thiazolyl-2-yl]-2-methylpropionamide (INCI: isobutyramidothiazolylresorcinol) is advantageous. A preferred content is 0.01% to 0.1% by weight based on the total weight of the composition.
[0018] According to the present invention, it is advantageous if the cosmetic product is characterized in that the composition contains one or more polar oils, such as ethers, esters, plant-based oils, particularly dioctyl ether, caprylic / capric triglycerides and / or coconut oil glycerides.
[0019] According to the present invention, it is advantageous if the cosmetic product is characterized in that the composition contains fatty alcohols, such as cetearyl alcohol and / or stearyl alcohol.

[0021] According to the present invention, it is preferred if the cosmetic composition is an emulsion, particularly an oil-in-water emulsion.
[0022] In such cases, emulsifiers such as polyglycerol-6 stearate and / or polyglycerol-6 behenate are preferred.
[0023] According to the present invention, preservatives such as hydroxyacetophenone, phenoxyethanol, ethylhexylglycerin, and 4-tert-butylcyclohexanol are also useful.
[0024] According to the present invention, it is advantageous if the cosmetic product is characterized in that the composition contains one or more gums, such as xanthan gum, sclerotium gum and / or vegan gum.
[0025] In addition to isobutyramide thiazolyl resorcinol, according to the present invention, it is advantageous if the cosmetic composition contains other active ingredients, such as panthenol, panthenol, and / or tocopherol.
[0026] In addition, the composition may contain acids such as citric acid, phosphoric acid, and lactic acid.
