Problems solved by technology

In the above-mentioned patents, polyvinyl alcohol, polyvinylpyrrolidone or a combination of both are used as film-forming agents, but polyvinyl alcohols are likely to irritate the skin when peeled off; polyvinylpyrrolidone is usually difficult to form a peelable film-forming agent alone. good film
[0004] Lac resin is a natural oligomer extracted from the secretion of lac insects. It has good degradability and is non-toxic to the human body. It has a large number of functional groups, so it is widely used in waterproofing Sealing materials, drug coatings and bioengineering materials, etc., but there is no use of shellac resin in tear-off masks as a film-forming agent

Embodiment 1

[0026] Embodiment 1, preparation of modified lac resin

[0027] Mix shellac resin and absolute ethanol at a weight ratio of 1:10, slowly drop into octenyl succinic anhydride, react in a water bath at 35°C for 1 hour, and maintain the reaction with 0.1mol / L aqueous sodium hydroxide solution during the entire reaction process The pH value of the system is 8.0-8.5. After the reaction, the reactant is centrifuged and washed three times with 70% ethanol solution, and dried to obtain the modified shellac resin.

Embodiment 2～4

[0031] Dissolve titanium dioxide and talcum powder in deionized water in mixing tank A, add glycerin, hydrolyzed oat protein, nonapeptide-1 and white fungus extract, heat to 80°C and stir evenly to form a water phase; mix ethanol, polyvinylpyrrolidone, Mix modified s...

experiment example 1

[0042] Experimental example 1, sensory evaluation

[0043] Select 80 volunteer subjects to carry out skin test, divide into 8 groups at random, each group has 10 people (age 23~40 years old), take embodiment 2~4 and comparative example 1~5 described facial mask composition as test sample After washing the face, each subject took an appropriate amount of sample and applied it on the facial skin, and took it off after it was completely dry. Difficulty and degree of dispersion of powder particles were evaluated, and the evaluation results are shown in Table 1 below.

[0044] Table 1 Sensory evaluation results

Abstract

The invention relates to a peel-off mask composition and a preparation method thereof. The peel-off mask composition comprises the following components by mass: 5-20% of powder particles, 1-8% of a film forming agent, 5-12% of a humectant, 1-6% of grease, 3-10% of alcohols and 45-75% of deionized water, and the film forming agent is polyvinylpyrrolidone, a modified shellac resin or a combination thereof. The peel-off mask composition can effectively remove aged cuticle and convey nutritional ingredients to the skin, the powder particles can be stably and uniformly distributed in a product, andthe product has a better appearance; and by adding the modified shellac resin to cooperate with the polyvinylpyrrolidone, indexes such as film forming quality and a stripping property of the mask composition are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a peel-off mask composition and a preparation method thereof. Background technique [0002] The advantage of the tear-off mask (peel-off mask) is that the mask product is applied to the face. After the mask dries, a peelable film can be formed without washing with water. When peeling off, the aging cuticle and sebum in the pores and various Aging substances are removed together, and nutrients are delivered to the skin at the same time. [0003] Chinese patent application CN106806248A discloses a peel-off cherry enzyme facial mask and a preparation method thereof. Using kaolin and zinc oxide as film-forming agents, reducing the amount of synthetic film-forming agents added to the mask, and adding chitosan and dextrin as supplements to film-forming agents, improves the tension of the peel-off mask , The film-forming property of the prepared mask is good, and the film-forming sp...
