Polygonatum odoratum extract as well as preparation method and application thereof

Abstract

The invention belongs to the field of daily chemicals. The invention discloses a polygonatum odoratum extract. The polygonatum odoratum extract is prepared from the following components in percentageby mass of 1-60% of polygonatum odoratum, 10-30% of sorbitol, 0.1-10% of a surfactant, 0.01-2% of a pH regulator and the balance of pure water. The polygonatum odoratum essence in the polygonatum odoratum extract is a compound which has a similar structure as sorbitol and contains a large number of hydroxyl groups, and a component which can be solubilized or emulsified by a surfactant, and when the polygonatum odoratum extract is applied to a washing product containing the surfactant, the polygonatum odoratum extract has good self-stability, and plant effective substances are not easy to separate out; and meanwhile, the irritation of the surfactant can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to a Polygonatum Polygonatum extract and its preparation method and application. Background technique [0002] Surfactant residue and irritation in surfactant-containing cleaning and care products are recognized as one of the important sources of damage to human skin in the field of daily chemicals. For example, the problem of shampoo-induced itching, the applicant has found through a large number of population experiments that shampoos cause itching due to the following three reasons: 1. The proliferation of harmful microorganisms on the scalp; 2. Excessive cleansing of the scalp; 3. .Surfactant irritation. Among them, the first two can be controlled by adjusting the proportion of the formula and the type of raw materials, but the problem of surfactant irritation is difficult to solve. The raw materials commonly used in this field to reduce irritation, such as ...

AI Technical Summary

Problems solved by technology

However, the plant extract prepared by the above method contains a large amount of ions, is incompatible with surfactants, and is easy to separate out, resulting in unstable products, and polysaccharide compounds are different from steroidal saponins and flavonoids, and polysaccharide compounds have better water solubility. Its structure can withstand high temperature of 100 ℃, and it does not need to avoid too high temperature

At the same time, the extraction efficiency of polysaccharides by traditional extraction methods is also very low, because polysaccharides are one of the most effective substances in Polygonatum Polygonatum. There is still a large difference in the content of
