Infant chapping-prevention and skin-care composition for enhancing skin barrier function and preparation method thereof

Abstract

The invention provides an infant chapping-prevention and skin-care composition. The infant chapping-prevention and skin-care composition is prepared from the following components: an anti-freezing andmoisturizing composite component, an active polysaccharide pre-mixed solution, a compound plant extract matrix solution, a ceramide nano-lipid pre-dispersant, an oil-phase base solution and a water-phase base solution. The composition has the effect of enhancing a skin barrier function and good air pollution isolation performance and can be used for assisting to repair chapped skin; the composition has mild properties and no irritation and is especially suitable for the skin of infants.

Description

technical field

[0001] The invention relates to the field of children's skin care products, in particular to an anti-crack skin care composition for infants and young children that enhances the skin barrier function and a preparation method thereof. Background technique

[0002] The skin is the first line of defense of the human body, but the skin thickness of infants and young children is far less than that of adults, the stratum corneum is immature, and the dermis and fibrous tissue are thin. Therefore, the skin sensitivity of infants is much higher than that of adults, and they are extremely vulnerable to changes in the external environment, such as cold, dry, and harsh environmental problems such as smog and sand, which will increase the discomfort of infants' skin. Especially in dry, cold and foggy environments, it is easy to cause damage to the skin of infants and young children, especially the exposed parts such as the face and hands. In mild cases, the skin may becom...
