BIS-HEMA POLY(1,4-BUTANEDIOL)-14/IPDI COPOLYMER.

Valuable CAS 2134098-86-3 / BINDING, SKIN CONDITIONING

BIS-HEMA POLY(1,4-BUTANEDIOL)-14/IPDI COPOLYMER is a synthetic polymer that acts as a binding, film-forming, and skin conditioning agent. Its larger molecular structure makes it less reactive and generally unable to penetrate the skin.

Binding Film-forming Skin Conditioning

Science

This copolymer ensures product cohesion and forms a protective film on the skin, helping to maintain its condition. Its macromolecular size prevents skin penetration, reducing the likelihood of allergic or inflammatory reactions.

Stability

For optimal stability, formulators may seek resins with very low MEHQ content (<100 ppm). Viscosity should not exceed 15,000 cP at 60°C to avoid heating during use.


Safety

CIR Status
Safe as used
Sensitization risk Low

As a copolymer, its larger molecular size significantly reduces skin penetration and sensitization potential compared to HEMA monomers. It is not classified as a CMR, PBT, vPvB, Endocrine Perturbator, or Respiratory sensitizer.
