Abstract

The invention discloses a preservative for a skin care product. The preservative comprises the following components in parts by weight: 1 to 3 parts of bronopol, 4 to 8 parts of methyl parahydroxybenzoat, 0.1 to 0.5 part of benzoisothiazolinone and 1 to 3 parts of plant preservative ingredients, wherein the plant preservative ingredients are prepared by the following method of mixing and crushing 1 to 6 parts by weight of mangnolia officinalis, 3 to 5 parts by weight of clove, 1 to 3 parts by weight of tea leaves, 3 to 6 parts by weight of orange peel, 3 to 6 parts by weight of witch hazel and 1 to 6 parts by weight of rose, and adding ethanol for reflux extraction; performing vacuum concentration on extraction liquid to obtain extract with the relative density of 1.1 to 1.3; performing spray drying to obtain the plant preservative ingredients. The preservative disclosed by the invention can be better matched with raw materials of most skin care products; the bacteriostatic ability of the preservative is not influenced by surfactant, protein and Chinese herbal medicinal additives in the skin care product; in addition, the preservative is high in safety and low in stimulation.

Description

technical field [0001] The invention belongs to the technical field of additives for skin care products, and in particular relates to a preservative for skin care products. Background technique [0002] Some ingredients in skin care products, such as organic components such as lipids, hydrocarbons, and water-soluble polymers, can not only provide rich nutrients such as carbon sources and nitrogen sources for microbial growth, but also provide chemical nutrients for microbial growth through oxidation. can. Once encountering the right environment, the microorganisms in skin care products will grow, multiply, and make them spoil. The deterioration of skin care products caused by microorganisms is mainly manifested by decomposing the matrix of skin care products, causing turbidity, precipitation and color changes in the products. The acidic products generated by their metabolism change the pH of the products, and the generated gas causes foaming, swelling, and affects the appea...
