Suspension composition containing liquid crystal form

Abstract

The invention belongs to the field of chemicals for daily use, and discloses a suspension composition containing a liquid crystal form. The composition includes an anionic surfactant, glyceryl monohydroxystearate, an ampholytic surfactant, a nonionic surfactant, a crystallization promoting agent, polyol and pure water; and the anionic surfactant is an N-acyl amino acid surfactant whose stacking parameters V<h> / I<c>a<0> are less than or equal to 0.18. The composition takes the amino acid surfactant as the main surfactant, so that the composition is mild and low in irritation and suitable for sulfate-free systems; the liquid crystal form composition can make up the defects of pearlescent system, carbomer and other polymer systems, is good in compatibility and excellent in suspension performance and can be widely applied to care products, so that a novel suspension technology can be provided for the development of the care products; and the liquid crystal form of the composition can stabilized exist by adding the composition into the substrates of hair cosmetics, and massive linear structures can for spatial network structures in systems, so that good suspension capacities can be provided for particles in the systems.

Description

technical field [0001] The invention belongs to the field of daily chemicals and relates to a suspending composition containing liquid crystal form. Background technique [0002] Shampoos containing various "granule" ingredients, such as anti-dandruff agent zpt, silicone oil particles, appearance modifier flash powder, etc., due to density differences, such particles are easy to float or settle in the system, making the composition unstable. In order to improve the stability of these water-insoluble particles in the system, one or more suspension stabilizers must be added, such as pearlescent, carbo, etc., to ensure that these particles can be stably and uniformly dispersed and suspended in the entire composition system , and slow down or eliminate the movement of such particles. [0003] Carbo suspension and pearlescent suspension are two suspension systems widely used at present, but both systems have certain limitations. The carbomer system has high suspension performan...

[0006] On the other hand, the patent does not disclose that when the N-acyl amino acid surfactant is used as the main surface active agent in the liquid crystal system, which surfactant with amino acid structure can make glyceryl hydroxystearate form liquid crystal Morphology

What kind of N-acyl amino acid surfactants can interact with glyceryl hydroxystearate to form a liquid crystal morphology structure is not disclosed in the prior art, and not all N-acyl amino acid surfactants can make glycerol hydroxystearate The ester forms a liquid crystal solid state structure, and if an inappropriate V h / I c a 0 If the value of the surfactant is low, the liquid crystal structure cannot be formed. At this time, glyceryl hydroxystearate mainly exists in the form of molecular aggregates in the system. In this case, the composition does not have the suspending function, and is even unstable, resulting in demulsification
