Hyaluronic Acid
Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad.
Carbomers
Carbomer powder is an acrylic polymer with polyalkenyl ether cross-linking. It has strong hygroscopicity and certain acidity (because it contains carboxyl groups). It can be neutralized with alkaline substances to form a highly transparent gel. Good viscosity increasing effect. Carbo resin can thicken without being affected by temperature under low dosage, and can make some insoluble additives (particles, oil droplets, etc.) achieve permanent suspension.
