It forms a thick viscoelastic solution in water with physiological pH and ionic strength.It is produced by fermentation of lactic acid cocci.It is a white or off-white particles or powder with no odor.
Sodium hyaluronate powder can widely used for its unique physical properties, such as creams, lotions, gels, lotions, eye care products, anti-wrinkle products, whitening and freckle-removing products, sunscreens, after-sun repair products, scar repair products, Acne products, facial cleansers, etc., shampoo and hair care products have also been used in recent years.
