Problems solved by technology

[0003] At present, there are more than 60 kinds of preservatives allowed to be used in the world, and more than ten kinds are commonly used. In my country, there are 51 kinds of preservatives allowed in the "Safety and Technical Specifications for Cosmetics" (2015 Edition), all of which are chemically synthesized. Most of these preservatives are irritating, sensitizing or even biologically toxic, and their safety has always been concerned. Relevant regulations and standards have strict restrictions on their usage and scope in cosmetics

Abstract

The invention discloses a cosmetic preservative based on natural plant components and its application. The preservative is compounded by the following raw materials in parts by mass: 20-30 parts of litsea cubeba essential oil, 5-15 parts of Hedyotis diffusa extract 60-70 parts of glycol mixture. The diol mixture is formed by mixing 1,2-pentanediol and 1,2-hexanediol in a mass ratio of 2-4:1. The present invention adopts the mixed diol extract of Hedyotis diffusa, and compound it with Litsea Cubeba essential oil and dibasic alcohol mixture to make a compound preservative with high safety, broad-spectrum antibacterial and excellent antiseptic effect, which replaces the traditional Chemically synthesized preservatives reduce the potential safety risks of chemically synthesized preservatives, and have great application value and market prospects.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a cosmetic preservative based on natural plant ingredients and its application. Background technique [0002] Cosmetics are rich in nutrients and sufficient in water, which are especially suitable for the growth and reproduction of microorganisms. Therefore, they are extremely susceptible to contamination by microorganisms during production, storage and use, resulting in spoilage. Products contaminated by microorganisms have potential safety hazards, which can cause skin allergies, irritation and even infection, and bring harm to the health of consumers. Therefore, anti-corrosion is a very important link in the quality control of cosmetics production. Adding preservatives is widely used and effective method. [0003] At present, there are more than 60 kinds of preservatives allowed to be used in the world, and more than ten kinds are commonly used. In my country, there are 51 ...
