Description

Novel cosmetic antiseptic composition

Technical Field

Background

Preservatives are a class of food additives that inhibit microbial activity and prevent spoilage of products. To preserve the product for a certain period of time, measures must be taken to prevent microbial infection and proliferation. The use of preservatives has proven to be one of the most economical, effective and straightforward ways to achieve the above objectives.

The existing preservatives are generally divided into two categories, one is a chemical preservative and the other is a natural preservative. Chemical preservatives generally suffer from varying degrees of contamination and low toxicity. The natural preservative has the defects of narrow antibacterial spectrum, high price, peculiar smell and variegated colors. Therefore, the development of a safe, mild and efficient preservative system from natural plants as a substitute for chemical preservatives is a research hotspot in the field of cosmetic preservation at present. The natural plant-derived preservative takes bacteriostatic active ingredients extracted from natural plants as main active ingredients, and at present, natural plant preservatives on the market are rare, and have the problems of large taste, reduction of product influence on stability and the like.
