Problems solved by technology

The deterioration of cosmetics caused by microorganisms is mainly manifested in the decomposition of the matrix of cosmetics, causing turbidity, precipitation and color changes in the product. The acidic products generated by its metabolism change the pH of the product, and the generated gas causes foaming and swelling, affecting the appearance and smell of the product. , In addition, microorganisms may also produce toxins, causing skin allergies and even skin infections

Abstract

The invention discloses a pure natural preservative for cosmetics. The pure natural preservative is prepared from the following components in parts by weight: 1-3 parts of lotus leaf, 3-5 parts of honeysuckle, 2-5 parts of folium ginkgo, 1-3 parts of dark plum and 1-5 parts of shaddock peel. A preparation method of the pure natural preservative comprises the following steps: (1) crushing the raw materials and mixing, adding water for decoction, filtering, and concentrating filtrate until the crude drug concentration is 1-1.3g / ml to obtain a concentrated solution; (2) adding ethyl alcohol into the concentrated solution until the ethyl alcohol concentration is 75-80 volume percent, standing for precipitation, and filtering out precipitate to obtain a clear solution; (3) decolorizing the clear solution with activated carbon, filtering and drying to obtain the pure natural preservative. The preservative is prepared by combining pure natural plant extracts, has a good antibacterial effect, is safe and non-toxic to human health, and has the advantages of anti-oxidation, skin whitening, anti-inflammation and the like.

Description

technical field [0001] The invention belongs to the technical field of cosmetic additives, in particular to a pure natural antiseptic used in cosmetics. Background technique [0002] Some ingredients in cosmetics, such as organic components such as lipids, hydrocarbons, and water-soluble polymers, can not only provide rich carbon sources, nitrogen sources, and other nutrients for microbial growth, but also provide chemical energy for microbial growth through oxidation. . Once it encounters the right environment, the microorganisms in the cosmetics will grow, multiply, and make it spoil. The deterioration of cosmetics caused by microorganisms is mainly manifested in the decomposition of the matrix of cosmetics, causing turbidity, precipitation and color changes in the product. The acidic products generated by its metabolism change the pH of the product, and the generated gas causes foaming and swelling, affecting the appearance and smell of the product. , In addition, micro...
