Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to hand cream and a preparation method thereof.

Background

Water shield, also called horseshoe, lake vegetable, water sunflower or dew sunflower, grows in ponds, lakes and marshes, is a perennial fresh water aquatic herb plant of the genus Brasenia of the family Nymphaeaceae, is fresh, tender and one of precious vegetables. The water shield has higher nutritive value, the water shield contains rich acidic heteropolysaccharide which is an immunopotentiator, can enhance the body immunity effect and prevent diseases, and also has stronger inhibiting effect on a plurality of tumors; the tender buds and petioles of the water shield are wrapped with transparent colloid, the appearance is crystal clear, and the taste is smooth; the water shield is rich in L-fucose, L-rhamnose, L-arabinose, D-xylose, D-galactose, D-mannose, D-glucuronic acid, etc.; the water shield is sweet, cold and nontoxic in nature, has the effects of clearing heat, detoxifying, resisting bacteria and diminishing inflammation and the like, and has the effect of inhibiting active substances such as tyrosinase, elastase, collagenase and hyaluronidase in the water shield extract through modern clinical pharmacological tests. Theoretically, all parts of the water shield can be used, but at present, people mainly eat the tender leaf part wrapped with rich viscose, and the utilization rate of other parts of the water shield is low.

The hand cream is a skin care product which can heal and smooth skin cracks and prevent and treat hand roughness and hand chap in autumn and winter, and hand skin can be more tender and moist after frequent use. Along with the promotion of people's consciousness of protecting the skin, people prefer high security and more effective hand cream more, however most hand cream freckle removal whitening and moisturizing effect are unsatisfactory now, simultaneously, also have photocatalysis and irritability to skin, block up the pore easily, harm hand skin.
