Embodiment

[0036] 1. Composition and liquid crystal structure of liquid crystal emulsifier of the present invention

[0037] Observation and verification method of liquid crystal structure: Sampling Olympus polarizing microscope, take a very small amount of sample (50μL) and drop it on the glass slide, cover it with a cover glass, so that the sample spreads on the glass slide in a thin layer, pay attention to exclude air bubbles, Under a polarized light microscope (200x), observe the quantity, morphological structure, and completeness of the liquid crystal formed by the sample, and take pictures to record the experimental results.

Embodiment 2

[0065] The result of Example 2 group and Example 3 group shows that after the present invention compounded the emulsifier of specific type and content, the higher alcohol of specific type and content and the liquid oil of specific type and content, the liquid crystal emulsifier of the present invention It also has anti-allergic and soothing biological activity.

[0066] However, the results of Comparative Examples 1-4 show that removing some components of the liquid crystal emulsifier composition of the present invention (for example, cumin oil, sodium stearyl glutamate or behenyl alcohol), or changing the liquid crystal emulsifier composition After increasing the dosage ratio of the components in the product, the anti-allergic and soothing effect of the liquid crystal emulsifier of the present invention becomes significantly worse, and even loses the anti-allergic and soothing effect.

Abstract

The invention provides a liquid crystal emulsifier having anti-allergy and soothing effects, and a preparation method and application thereof. The liquid crystal emulsifier mainly comprises sodium stearoyl lactylate, glyceryl stearate, behenyl alcohol, sodium stearoyl glutamate, fennel oil and the like. The liquid crystal emulsifier composition with the bionic sebum film design is prepared by compounding the emulsifier of a specific type and content, the higher alcohol of a specific type and content and the liquid grease of a specific type and content, and the formed liquid crystal structure is large in number, uniform in form and particle size, high in stability in a large pH range and good in stability. In addition, the emulsifier also has anti-allergy and soothing biological activity, so that when the emulsifier is applied to cosmetics, the skin cuticle reconstruction can be promoted, the moisture retention and water resistance of the skin are improved, and the composition has excellent use feeling.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a liquid crystal emulsifier with anti-allergic and soothing effects, a preparation method and application thereof. Background technique [0002] Liquid crystal is a state of matter between liquid and crystal in structure and mechanical properties. It has both the fluidity of liquid and the regularity of solid molecular arrangement. In 1969, Friberg et al. discovered for the first time that when a surfactant was added to the oil-water system, the third phase, the liquid crystal phase, was precipitated. At this time, the stability of the emulsion suddenly increased, which was due to the adsorption of liquid crystals. On the oil-water interface, a stable protective layer is formed to hinder the coarsening of droplets due to collision. At the same time, the existence of the liquid crystal adsorption layer will greatly reduce the long-range van der Waals force between the droplet...
