Abstract
The invention discloses a preparation method of a plant surface active agent composition. The invention mainly relates to a preparation process of a compound composition of a plurality of specific plant saponins, especially a preparation process as below: combined production of high purity plant saponins through efficient low temperature extraction, ultrasonic extraction, membrane separation and concentration, column chromatography purification and crystallization refining; and compound of the saponins according to a certain proportion to obtain the plant surface active agent composition. The plant surface active agent prepared by the invention can reduce stimulation of a traditional plant surface active agent, and can increase the surface tension and foaming performance.
Description
Technical field
The present invention relates to a kind of composite plant surface surfactant composition, said composition has emulsification, disperses, and clean, anti-bacterial, anti-itching effect, can be applied to shampoo, shower cream and clean product.
Background technology
Along with the raising of people's living standard and the enhancing of environmental protection consciousness, particularly in " cosmetics, bathing lotion ", there is in recent years the Harmful Residue event of hurting sb.'s feelings, make the whole society more pay close attention to the security of product to human body and environment.Because surfactant is that the form of filling a prescription adds in product and with human body and directly or indirectly contacts, finally enter nature; So develop nontoxic as far as possible and the free of contamination surfactant of ecological environment become to the focus that industry is paid close attention to.Plant surface activating agent be take natural plants as raw material, and process is pollution-free, and final products are nontoxic to human body, excitant is little and be easy to biodegradation.Beginning is applied in increasing articles for washing.But present stage, plant surface activating agent existed frothing capacity poor, formula is difficult for stable, and color is dark, and smell is the characteristic such as heavily, seriously restricted range of application.
Summary of the invention
The object of the invention is in order to overcome the defect of traditional plant surfactant, a kind of composite plant surface surfactant composition is provided.This plant surface surfactant composition has good surface-active, soil release performance, solubilising, foaming characteristic and foam stability; Acid and alkali-resistance, anti-hard water, compatibility are good; Nontoxic, excitant is little, easily biological-degradable.
For reaching the object of the invention, adopted following technical scheme:
A surfactant composition, is characterized in that the component that comprises following percentage by weight:
Concrete extraction and purification process is as follows:
