Abstract

The invention relates to the technical field of daily chemical products, and discloses an anti-oxidation and moisturizing liquid crystal composition, a preparation method and application thereof. The liquid crystal composition of the present invention comprises 0.01-5% Ophiopogon japonicus polysaccharide, 0.5-15% milk thistle seed oil, 1-20% emulsifier, 1-20% co-emulsifier, 5-35% liquid oil, thickened 0.01-5% preservative, 0.1-10% preservative, and water as the balance. In the present invention, milk thistle seed oil and Ophiopogon japonicus polysaccharides are entrapped in the liquid crystal structure prepared by combining special materials, which has high overall stability and complete liquid crystal structure; it can form a good closed system on the skin and enhance the hydration of the skin , moisturizing performance and anti-oxidation effect are remarkable, and it has good application prospects in the field of cosmetics.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to an anti-oxidation and moisturizing liquid crystal composition and its preparation method and application. Background technique [0002] In daily skin care, moisturizing and anti-oxidation are important conditions to ensure skin health and delay aging. In recent years, out of doubts about the toxicity and irritation of chemical cosmetics, more and more scientific researchers tend to look for safe and efficient moisturizing and antioxidant active ingredients from natural plants. Ophiopogon japonicus polysaccharide is a natural plant polysaccharide extracted from Ophiopogon japonicus. It has the effects of moisturizing skin, fat and health, black hair, and anti-aging. It can absorb water from the atmosphere to keep the skin moist, and can also absorb water from the deep layer of the skin , to achieve moisturizing effect. Milk thistle seed oil is obtained from the p...
