Hydrolyzed Hyaluronic Acid CAS 9004-61-9
Cosmetics commonly used sodium hyaluronate, are relatively large molecular weight structure, skin external use, is not conducive to absorption basically stay on the stratum corneum. Therefore, the polymer sodium hyaluronate is degraded by biological enzymes to obtain sodium hyaluronate with a smaller molecular weight, which is called "hydrolyzed sodium hyaluronate".
Hydrolyzed hyaluronic acid and hydrolyzed sodium hyaluronate are not the same product, and the PH of hydrolyzed hyaluronic acid sold on the market is generally between 2.5 and 5.0. Some people think that the molecular weight must be below 10kDa to become hydrolyzed hyaluronic acid, but some people think that the molecular weight below 50kDa is hydrolyzed hyaluronic acid.

Hyaluronic acid can soften the stratum corneum and accelerate skin metabolism. Inhibit oil secretion and other functions. The molecular weight of hydrolyzed hyaluronic acid is relatively low, which can play the effect of transdermal absorption, deeply nourish the skin, improve skin elasticity and reduce wrinkles. Can be widely used in cosmetics and care products, such as serum, lotion, mask, eye cream, sunscreen, spray and so on.
The hydrolyzed sodium hyaluronate obtained by the enzymatic hydrolysis process has better biological activity and better permeability than the medium molecule macromolecule. It can penetrate the stratum corneum and enter below the stratum corneum, quickly supplement nutrients to the cells, rapidly absorb through the skin, repair damaged cells, improve cell activity, increase skin moisture content, fully lock in water, improve skin dryness and dehydration, and delay skin aging. It has a cosmetic effect and can also promote wound healing.
