Description
Technical field
The present invention relates to a kind of lysotropic liquid crystal, be specifically related to a kind of lysotropic liquid crystal and its production and use.
Background technology
Liquid crystal has anisotropy and the mobility of liquid, the seriality of crystal, between solid and liquid in
Jie's phase.In certain temperature range, the physical property such as the heat of the existing crystal of liquid crystal, optical, electrical, magnetic, have again liquid mobility,
The engineering properties such as viscosity, deformation.According to the condition formed and composition, liquid crystal can be divided into two big class, i.e. thermotropic liquid crystal and molten causes
Liquid crystal.Thermotropic liquid crystal is caused by temperature, can only exist, usually one-component in certain temperature range.Lysotropic liquid crystal
The system being made up of with solvent the compound meeting certain structural requirement, containing two or more component.
Thermotropic liquid crystal application in cosmetics, replaces the dyestuff in cosmetics to reduce dye mainly by thermotropic liquid crystal
The stimulation that skin is caused by material, gives the color that cosmetics are gorgeous simultaneously, and relevant report starts from the day at the end of the eighties in last century
This patent (JP K01/246209, JP K01/242690).Lysotropic liquid crystal applied research in cosmetics is more, but relevant
Report the most little.Lysotropic liquid crystal is added, owing to the rheological property of lysotropic liquid crystal is main in the preparation process of cosmetic emulsion
Showing as the behavior of non-Newtonian fluid, have yield stress and the highest viscoelasticity, the liquid crystal structure around oil droplet is in rheological characteristic
On serve the effect hindering cohesion, and the Van der Waals force between oil droplet becomes the least, therefore has increase emulsion stability
