Abstract

The invention relates to the technical field of daily chemical products, and discloses an anti-oxidative and moisturizing liquid crystal composition and a preparation method and application thereof. The anti-oxidative and moisturizing liquid crystal composition is prepared from 0.01-5% of ophiopogonpolysaccharide, 0.5-15% of silybum marianum seed oil, 1-20% of an emulgator, 1-20% of a co-emulsifier, 5-35% of liquid grease, 0.01-5% of a thickener, 0.1-10% of an antiseptic and balance water. The anti-oxidative and moisturizing liquid crystal composition and the preparation method and applicationthereof have the advantages that the silybum marianum seed oil and the ophiopogonpolysaccharide are encapsulated in the liquid crystal structure prepared by combining special materials, the overall stability is high, and the liquid crystal structure is complete, a good closed system can be formed on the skin, the hydration of the skin is enhanced, the moisturizing property and the anti-oxidativeeffect are significant, and the application prospect is wide 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 refined from the fr...
