Problems solved by technology

[0003] At present, cosmetics need to add preservatives to maintain their efficacy within the shelf life. However, some common cosmetic preservatives are represented by isothiazolinones, which are more irritating to the skin and have certain toxicity. Not broad-spectrum, small range of sterilization, poor antiseptic effect
In addition, the addition of preservatives may also affect the efficacy of cosmetics, and their existence will crowd out the proportion of active ingredients in cosmetics

Abstract

The invention discloses a high-efficiency preservative for cosmetics and a preparation method of the high-efficiency preservative. The preparation method comprises the following steps of adding 6-12 parts of fatty acid ester, 5-10 parts of paraben and 7-14 parts of allantoin to a container at the room temperature, heating the whole system to 35-40 DEG C through water bath, stirring the system evenly at 60-120 rpm, slowly, continuously and successively adding 36-68 parts of a solvent, 2-4 parts of the fatty acid ester, 3-6 parts of the allantoin, 3-6 parts of ethylhexylglycerin, and 6-12 partsof chitosan, adding materials while stirring at 90-150 rpm, completing material adding within 12-18 min, and the high-efficiency preservative for the cosmetics is prepared. According to the high-efficiency preservative for the cosmetics, environmental protection raw materials are adopted, through combination of the fatty acid ester, the paraben, and the allantoin, high-efficiency sterilization andantisepsis effects are achieved, when using, the antisepsis effect can be guaranteed with the dosage of 0.005%-0.02%, and impacts on human health does not exist.

Description

technical field [0001] The invention relates to the technical field of cosmetic additives, in particular to a high-efficiency preservative for cosmetics and a preparation method thereof. Background technique [0002] Cosmetics refer to fine chemical products that are spread on any part of the human body surface by smearing, spraying or other similar methods to achieve the purpose of cleaning, maintenance, beauty, modification, etc., so the safety of each ingredient is extremely important. [0003] At present, cosmetics need to add preservatives to maintain their efficacy within the shelf life. However, some common cosmetic preservatives are represented by isothiazolinones, which are more irritating to the skin and have certain toxicity. Not broad-spectrum, small range of sterilization, poor antiseptic effect. In addition, the addition of preservatives may also affect the efficacy of cosmetics, and their existence will crowd out the proportion of active ingredients in cosmet...
