Problems solved by technology

[0006] At present, there are also a small amount of reports about moisturizing emulsions with lamellar liquid crystals, but the emulsifiers used in existing moisturizing emulsions with lamellar liquid crystals are all liquid crystal emulsifiers, such as lecithin, sucrose esters, and phytosterols. , glucosides, these are currently commonly used liquid crystal emulsifiers, long-term research has found that these liquid crystal emulsifiers are costly, and the number of liquid crystals formed is small, and the droplet size is uneven.

Abstract

The invention relates to a whitening and moisturizing emulsion containing lamellar liquid crystals and a preparation method thereof. In the invention, an oil phase, an emulsifier, a higher alcohol, beeswax, dimethylsiloxane, vitamin E and vitamin C are mixed, heated and stirred, Obtain the oil phase; add glycerin, propylene glycol, panthenol, sodium hyaluronate, nicotinamide, and p-hydroxyacetophenone into the purified water, heat and stir to obtain the water phase; add xanthan gum and disodium EDTA into the purified water, Stir to obtain a water-soluble polymer solution; the above three phases are mixed together and emulsified at a certain homogeneous speed. After the emulsification is completed, stir to degas and cool. During the cooling process, add chamomile extract and stir to obtain a uniform and stable lotion. The emulsion obtained by the invention has good stability, uniform particle size, and contains a large amount of lamellar liquid crystal phase. The existence of the lamellar liquid crystal phase improves product stability and moisturizing effect, and the product has the functions of moisturizing, whitening and anti-oxidation.

Description

technical field [0001] The invention relates to a whitening and moisturizing emulsion containing lamellar liquid crystal and a preparation method thereof, belonging to the technical field of skin care products. Background technique [0002] With the improvement of people's living standards, people's demand and requirements for cosmetics are getting higher and higher, especially with the change of living environment, higher requirements are put forward for whitening and moisturizing products. Melanin is a protein present in the basal layer of everyone's skin, and it is the culprit that affects skin whitening. The irradiation of ultraviolet rays will change the melanin to form a substance that protects the skin, and then the melanin moves through the layers of cell metabolism to the epidermis of the skin, forming skin problems such as spots and uneven skin tone. [0003] Skin cells and tissues are prone to water loss. Once the water content of the skin is insufficient, it may...
