Bis Aminopropyl Dimethicone ●
TL;DR. This ingredient is a cationic conditioning and film-forming polymer used mainly in hair care to improve slip, combability, softness, and frizz control. It deposits especially well on damaged, negatively charged hair fibers.
What does Bis Aminopropyl Dimethicone do in a cosmetic formula?
This ingredient is a cationic conditioning and film-forming polymer used mainly in hair care to improve slip, combability, softness, and frizz control. It deposits especially well on damaged, negatively charged hair fibers.
Is Bis Aminopropyl Dimethicone clean?
It has clean-standard friction because many programs limit or exclude non-biodegradable synthetic polymers, even when skin irritation is generally low. The main formulation watchpoint is buildup on hair rather than sensitization.
Is Bis Aminopropyl Dimethicone sustainable?
This material is made from mineral-derived silicon chemistry and petrochemical organic groups. It is not readily biodegradable and may persist through wastewater or sludge pathways, so its environmental profile is weaker than renewable, biodegradable conditioners.
Is Bis Aminopropyl Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic as a synthetic organosilicon polymer. It does not align strongly with Green Chemistry preferences for renewable feedstocks and ready biodegradability, although it is effective at low use levels.
How does Bis Aminopropyl Dimethicone work chemically?
The molecule has a flexible Si O backbone with it functionality, which gives it cationic character under mildly acidic conditions and strong affinity for damaged hair surfaces. It is commonly used through emulsions or pre-blends, with deposition favored around pH 4 to 6 and influenced by surfactant system, charge balance, and rinse conditions.
