1. Cosmetic Grade Sodium Hyaluronate
Sodium hyaluronate which is also called hysluronic acid(HA) is a natural biotic component, widely existing in skin and any other tissue. It has outing moisture keeping ability, thus called Natural Moisturing Factor(NMF)in the word. It is the best component used in cosmetics for moisture keeping in the nature.
When sodium hyaluronate applied to the skin, macromolecule sodium hyaluornate can form an air permeable thin layer and keep the skin smooth and moist, and protect the skin from bacteria, dust, and ultraviolet ray. With low molecular sodium hyaluronate penetrating into corium, it will slightly enlarge blood capillaries, speed circulation of blood, improve intermediary metabolism and nourishment absorbing ability of skin, thus eliminating wrinkles, increasing skin’s elasticity and delaying its aging. Sodium hyaluronate as well can further hyperplasia of epidermis call, clean oxygen free radical, prevent and rehabilitate breach of skin. Its aqueous solution has very high viscosity which can make water become thicker. Creams made by means of emulsifying sodium hyaluronate with oil is fine and homogeneous with stable emulsification.
Sodium hyaluronate is the beat natural moisturizing component used in cosmetics. It has a good compatibility and can be added in various cosmetics such as cream, lotion, cosmetic water, essence, cleansing milk, liquid for bath, ingreeient of hair washing and protection and lip stick. The suggested volume of use is about 0/05%-0.5%.
2. Food Grade Sodium Hyaluronate
There are about 15g sodium hyaluronate in a human body. It plays an important role in human biologic activity. With the decrease of sodium hyaluronate volume in skin, the water retaining ability of the skin is weakened. The decrease of sodium hyaluronate volume in other organs will lead to arthritis, arteriosclerosis and brain atrophy. All in all, the decrease of sodium hyaluronate bolume in human body will lead to premature senility.
Food grade sodium hyaluronate can increase the bolume of sodium hyaluronate in human body. By digestubf and absorbing sodium hyaluronate, skin can be made moist, smooth, soft and slastic. Food grade sodium hyaluronate can prevent arthritis, arteriosclerosis and brain atrophy. Food grade sodium hyaluronate can make one be rich in energy.
