Embodiment 1

[0019] A preservative for cosmetics, comprising the following raw materials in parts by weight: 10 active components, 4 synergists, and 86 solvents. Wherein, the active component is the bark extract of Magnolia officinalis; the synergist is 1 weight part of glycerin caprylate and 3 weight parts of sorbitan caprylate; and the solvent is 1,3-propylene glycol.

[0020] The preparation method of this preservative for cosmetics is:

[0021] 1. Preparation of Magnolia officinalis bark extract: Wash Magnolia officinalis bark, dry it to constant weight, and then pulverize it. The particle size is ≤ 1 mm. Add 8 times its own mass of ethanol to soak for 30 minutes, and then set it in a microwave ultrasonic integrated extractor. Set the temperature at 50°C, follow the sequence of microwave radiation for 30-60 minutes, and ultrasonic for 30 minutes, repeat 4 times. After the extract is hot, filter it with a filter cloth of 400 mesh or above. After filtering with cloth, combine the filtra...

Abstract

The invention discloses a cosmetic preservative based on plant source and preparation method thereof. The preservative is composed of active components, a synergist and a solvent, and the active components are a mangnolia officinalis bark extract and / or a circium japonicum extract and / or a pepper extract. In the preparation process, the active components extracted by the processes of microwave ultrasonic extraction and the like and the synergist are sequentially added into the solvent, uniformly stirred, mixed and filtered, and the obtained liquid is the finished cosmetic preservative. Compared with the prior art, the cosmetic preservative is mild in effect, safe and environmentally friendly, and after the preservative is added into smoothing toner and moisturizing liquid according to the adaptive mass ratio, the challenge experiment according to the American USP27 (51) microorganism preservative effect test is passed, and the preservative has the advantages of being good in stability, wide in antibacterial spectrum, high in preservative effect and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of auxiliary preparations for daily cosmetics, and in particular relates to a preservative for cosmetics based on plant sources and a preparation method thereof. Background technique [0002] According to the requirements of Chapter III of Cosmetics Safety and Technical Standards (2015 Edition), there are 51 kinds of preservatives allowed in cosmetics, including triclosan and triclocarban. Because these preservatives will cause certain negative effects on the human body during daily use, the market has limited requirements for them. With the improvement of social science and technology, people's awareness of self-protection and self-protection has been continuously strengthened, and requirements have been put forward for the chemical ingredients used in cosmetics, especially in recent years. For example, the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences reported that both t...
