Frequently Asked Questions
What is hyaluronic acid?
Hyaluronic acid (HA, CAS 9004-61-9) is a naturally occurring glycosaminoglycan biopolymer. In personal-care manufacturing it is used as a humectant and skin-conditioning ingredient and as a film-forming biopolymer in serums and gels. RawSource supplies it in bulk for formulators.
What does hyaluronic acid do in a formulation?
It acts as a humectant — a water-binding ingredient — in skincare emulsions, and as a film-forming biopolymer in leave-on serums and gels. Performance depends on molecular weight, which affects viscosity and film behavior.
What molecular weights of hyaluronic acid are available?
Hyaluronic acid is supplied across low-, medium-, and high-molecular-weight ranges, which differ in solution viscosity and feel. Specify your target molecular-weight range when requesting a quote; the CoA confirms the lot specification.
What is the HS code for hyaluronic acid?
It classifies under HS 3913.90 (natural polymers and modified natural polymers, n.e.s., in primary forms). Confirm destination-country tariff treatment with your customs broker; RawSource supplies documentation per shipment.
How is bulk hyaluronic acid packaged and priced?
HA is supplied as a powder in sealed containers sized for manufacturing use. Pricing is grade- and volume-dependent and quote-based — request a bulk quote with your target volume and molecular weight; a CoA and SDS accompany the order.
What is the REACH and TSCA regulatory status of Hyaluronic Acid (HA)?
Hyaluronic Acid (HA) (CAS 9004-61-9) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
