A moisturizing composition and its preparation method and application

Abstract

The present invention discloses a moisturizing composition and its preparation method and application. In terms of weight percentage, the moisturizing composition of the present invention includes the following components: 5% to 40% other alcohol moisturizers, 0.1% to 5% panthenol, 0.1% to 8% grease, 0.01% to 2% emulsifier, 0.001% to 0.05% polyquaternium-61, 0.1% to 1% other cationic conditioning agents, and the remainder is water. The moisturizing composition of the present invention can form a kind of outer layer positively charged polymer inclusion body that wraps grease, panthenol, etc., which can be combined with the negative charge of the skin during the cleaning process, so that some water-soluble moisturizers are not easily washed away by water during the flushing process, thereby adhering to the skin surface, providing a sense of not being tight and moisturizing after cleaning. The moisturizing composition of the present invention can be widely used in cosmetics to play a role in moisturizing, and is particularly applied to wash-off cosmetics.

Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a moisturizing composition and a preparation method and application thereof. Background Art

[0002] As people's living standards improve, facial cleansing products are used more and more widely. Cleansing is the first step in skin care and the top priority of skin care. Only by thoroughly removing the dirt and excess oil attached to the skin surface can the skin care products used later be absorbed by the skin and achieve skin care effects. However, frequent facial cleansing not only removes dirt, but also washes away the moisturizer and oil on the skin surface, which causes many people to feel dry and tight after cleansing.

[0003] Therefore, researchers will add some moisturizers when developing cleansing products. Unfortunately, the moisturizers added to cleansing products are often washed away by water during the cleaning process and do not stay on the skin surface to moisturize the skin.

[0004] Therefore, it is urgently needed by consumers and has great application prospects to develop a composition that can still adhere to the skin surface to moisturize and repair the sebum film even after washing with water after cleansing, and use it in rinse-off products.
