Problems solved by technology

However, because of zein and bentonite are rough solid powders, the formed Pickering emulsion has an astringent feel when applied to the skin, and the solid powder is easy to be rubbed out, which is often called "easy to muddy" in the cosmetics industry; and The interface film of Pickering emulsion is not strong, and usually cannot pass the environmental stability requirements of -10°C to 50°C usually required by the cosmetic industry, so Pickering emulsion is not practical in the cosmetic industry and is hardly adopted

Abstract

The invention relates to a mild emulsifier with good salt tolerance. The mild emulsifier is characterized by comprising, by weight, 30-70% of diisopropyl sebacate, 25-65% of wetting agents, 1-5% of hydroxypropyl methyl cellulose stearin oxo-ether and 1-5% of rice chaff extract. The mild emulsifier has the advantages of good salt tolerance, mildness, zero skin irritation and the like.

Description

technical field [0001] The invention relates to the technical field of emulsifiers for cosmetics, in particular to a mild emulsifier with good salt tolerance. Background technique [0002] In recent years, people have higher and higher requirements for the efficacy of cosmetics, and consumers hope that cosmetics can provide real and significant effects. In order to achieve better efficacy, it is necessary to increase the amount of functional active ingredients in cosmetics. Most of the functional ingredients are highly ionic, such as vitamin C magnesium phosphate for whitening, sodium hyaluronate for moisturizing, etc., are strong Ionic ingredients. However, most emulsifiers currently have a low tolerance to salt, and a high amount of active ingredients will lead to unstable phenomena such as water-oil separation in the emulsified product. [0003] In addition, the vast majority of emulsifiers currently on the market are surfactants in terms of chemical structure. After the...
