Question 1

What does BisPropane/Bisaminomethylnorbornane Copolymer do in a cosmetic formula?

Accepted Answer

This ingredient is a synthetic film-forming resin used to improve adhesion, gloss, hardness, and wear in nail color and other long-wear formats. It helps create a durable, solvent-resistant coating after the formula dries.

Question 2

Is BisPropane/Bisaminomethylnorbornane Copolymer clean?

Accepted Answer

From a clean-beauty perspective, this material has friction because it is a synthetic specialty polymer with possible residual monomer or oligomer considerations. It is generally expected to have low skin penetration as a high-molecular-weight resin, but many stricter standards screen out this type of chemistry.

Question 3

Is BisPropane/Bisaminomethylnorbornane Copolymer sustainable?

Accepted Answer

This material is primarily petrochemical-derived and is not expected to be readily biodegradable. Once released as film fragments, it can contribute to persistent synthetic polymer load in the environment.

Question 4

Is BisPropane/Bisaminomethylnorbornane Copolymer COSMOS-approved?

Accepted Answer

It is not aligned with COSMOS organic or natural standards because it is a synthetic, nonbiodegradable resin outside the usual permitted natural-origin ingredient categories. Its fit with Green Chemistry is weak due to nonrenewable feedstocks, limited biodegradability, and specialty polymer processing.

Question 5

How does BisPropane/Bisaminomethylnorbornane Copolymer work chemically?

Accepted Answer

The molecule is a high-molecular-weight copolymer built from rigid cyclic amine and aromatic epoxide-derived building blocks, giving hard, adhesive films with good solvent resistance. It is usually used in low-water or anhydrous coating systems, where performance depends more on solvent compatibility, drying behavior, and residual reactive groups than on pH.
