Description

Technical Field

[0001] The invention relates to cosmetic preparations, in particular to spot-lightening and whitening skin care products and a preparation method thereof, and in particular to a facial mask with spot-lightening and whitening effects and a preparation method thereof. Background Art

[0002] For a long time, freckle-removing and whitening cosmetics targeting skin problems such as dull skin tone, uneven skin tone, and spots have been very popular among consumers, and the market size of freckle-removing and whitening products has continued to grow. Freckle-removing and whitening cosmetics can be divided into two types: chemical whitening and physical concealing. In particular, chemical whitening products can inhibit the production of melanin, block the deposition of melanin, achieve a whitening effect, and effectively improve skin condition.

[0003] There are many kinds of freckle-removing and whitening ingredients. Plant extracts are very popular because of their good whitening and freckle-removing functions, and the advantages of being natural and non-irritating. Adding some extracts with anti-inflammatory and antibacterial effects can expand the scope of use of whitening products and is very friendly to consumers with sensitive skin.

[0004] In terms of improving skin tone uniformity and promoting absorption, the use of silk fibroin and sodium hyaluronate can, on the one hand, promote collagen synthesis, enhance skin elasticity and help promote pigment decomposition, making skin tone more even; on the other hand, it can form a breathable film on the skin surface, which helps lock in moisture and has a long-term moisturizing function. Low-molecular sodium hyaluronate is more easily absorbed through the skin, which helps the absorption of functional materials such as plant extracts. Summary of the invention

[0005] The present invention aims to provide a facial mask with the effect of lightening spots and whitening the skin.

[0006] Another object of the present invention is to provide a method for preparing a facial mask with spot-lightening and whitening functions.

[0007] The object of the present invention is achieved through the following scheme: A facial mask with the effect of lightening spots and whitening skin is composed of the following three components, and the content of the components by weight percentage is as follows: Component A: deionized water 70-90%, Tween 80 0.6-3%, distearic acid glyceryl 5-20%, sodium hyaluronate 0.1-1%, dextran 0.1-0.5%, poloxamer 0.01-1.5%; Sodium hyaluronate is sodium hyaluronate with a molecular weight below 1 million Da; Component B: Chinese herbal medicine extract 0.1~3%, silk fibroin 0.1~0.5%, xanthan gum 4~10%; The Chinese medicine extract is at least one of ginseng monomer saponin, grape seed extract, pomegranate extract, lemon extract and at least one of coix seed extract and peony extract; Component C: 1~5% 1,3-butanediol, 0.0~0.5% flavor, 0.0~0.3% preservative; The essence is one of lavender extract, rosemary extract and rose extract; The present invention provides a method for preparing a facial mask having the effect of lightening spots and whitening skin, which is characterized by comprising the following steps: Weigh component A in proportion, stir it in a rotor-stator stirring system to fully mix and emulsify it, keep the temperature at 60-80°C, then continue stirring for 20-30 minutes under vacuum, and then stand it under vacuum to defoam; Then weigh component B and component C in proportion, add them to the emulsified rotor-stator stirring system, stir evenly, wait for the temperature to drop to room temperature, and leave it for one day.

[0008] The invention discloses a facial mask with the effects of lightening spots and whitening and a preparation method thereof. The facial mask comprises three components A, B and C. Tween 80, glyceryl distearate, sodium hyaluronate, dextran and poloxamer are mixed with deionized water, emulsified, and then functional extracts, flavors, preservatives and the like are added. Low molecular weight sodium hyaluronate is easily permeable and can increase the absorption of nutrients. Traditional Chinese medicine extracts are used as functional additives and have the functions of improving skin whiteness and reducing pigmentation. Silk fibroin can promote collagen synthesis, enhance skin elasticity and help promote pigment decomposition to make skin color more uniform. The performance of various components is comprehensively utilized so that the facial mask not only has the effects of lightening spots, whitening, hydrating and moisturizing, but also has the functions of anti-inflammatory and antibacterial, and is suitable for use on various skin types.
