preparation example Construction

[0047] The present invention also provides a preparation method of the above-mentioned antiseptic composition, comprising: mixing Burnet eucalyptus extract, Hibiscus hibiscus leaf extract and optional auxiliary materials to obtain the antiseptic composition. The method has the advantages of simple process and easy operation. The advantage of convenience. In some preferred embodiments, the Burnet eucalyptus extract and hibiscus hibiscus leaf extract are first dissolved in a mixture of deionized water and a humectant, then a solubilizer is added and mixed evenly, and the insoluble matter is separated to obtain the antiseptic composition.

[0048] In some preferred embodiments, the anti-corrosion composition is prepared with reference to the following process parameters, and the effect is better:

[0049] i) Mix deionized water and polyol, stir and heat up to 40-60°C;

[0050] ii) Add Burnet extract and hibiscus leaf extract, stir to dissolve, stirring speed 200-600r / min;

Abstract

The invention provides a preservative composition for a cosmetic, a preparation method and application of the preservative composition, and the cosmetic, and relates to the technical field of cosmetics. According to the preservative composition, a garden burnet root extract and a cottonrose hibiscus leaf extract are combined to serve as an active ingredient in the preservative composition, and theobtained composition has a good antibacterial effect, and has good bacteria inhibition effects on common microorganisms in the cosmetic, such as candida albicans, aspergillus niger, escherichia coliand saccharomycetes. The cosmetic comprising the above preservative composition has the advantages of being less susceptible to spoilage and being lower in sensitization.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a preservative composition for cosmetics, a preparation method, application and cosmetics thereof. Background technique [0002] Preservatives are a class of additives that prevent the growth of microorganisms and prevent product spoilage. In cosmetics, the addition of preservatives can avoid product deterioration, odor, and spoilage caused by microbial activities in cosmetics, prolong the shelf life of products, and prevent consumers from having adverse effects due to the use of cosmetics contaminated by microorganisms. At present, my country's "Safety and Technical Specifications for Cosmetics" (2015 Edition) stipulates 51 preservatives, among which the widely used preservatives mainly include parabens, formaldehyde releasers, benzyl alcohol and its derivatives, methyl iso Thiazolone or phenoxyethanol, etc., there are many kinds. [0003] Most cosmetic preservatives are main...
