Description: Biotechnologically produced from glucose, soy peptone & yeast extract. Hyaluronic acid is a natural polysaccharide (large sugar molecule) that occurs in various tissues (skin, synovial fluids of joints, connective tissues). Responsible for tissue hydration, lubrication, & tissue stability, holds 500 times its own weight of water. White powder, no odor. Soluble in water. ph 5-8.5 in 5% aqueous solution. Shelf-life up to 3 years if stored protected from humidity and microbial contamination. CAS# 9067-32-7.

INCI Name: Sodium hyaluronic acid.

Properties: Most powerful moisturizer & humectant known so far, provides smoothness & softening to the skin, excellent anti-wrinkle effects, promotes growth of new skin cells after peelings, supports wound healing.

Use: Typically used at 0.1 - 1%. Hyaluronic acid is not readily soluble in water as it binds water very quickly forming a gel. Hyaluronic acid needs to be carefully sprinkled into the water under constant high-speed stirring (preferably with a hand mixer or vortex mixer). The mixture starts then thickening quickly and becomes a gel. At the point no additional hyaluronic acid can be added as there is no water left for hyaluronic acid to be dissolved in (additional hyaluronic acid would only form lumps).

Application: Hydrating gels, moisturizing creams & lotions, anti-aging & anti-wrinkle products, pre/after sun lotions, protecting / nourishing & moisturizing skin care products, treatments for sensitive, dry skin.
