Bis-Carboxydecyl Dimethicone ●
TL;DR. This ingredient is primarily a conditioning and film-forming agent, used to add slip, softness, and a smooth feel in hair and skin formulas. Its carboxyl-functional structure can also help with deposition and compatibility in emulsions.
What does Bis-Carboxydecyl Dimethicone do in a cosmetic formula?
This ingredient is primarily a conditioning and film-forming agent, used to add slip, softness, and a smooth feel in hair and skin formulas. Its carboxyl-functional structure can also help with deposition and compatibility in emulsions.
Is Bis-Carboxydecyl Dimethicone clean?
From a clean-beauty perspective, it faces friction because many standards restrict synthetic organosilicon polymers, even when irritation potential is generally low. The concern is mainly persistence and restricted-list status, not routine sensitization.
Is Bis-Carboxydecyl Dimethicone sustainable?
This material is synthetic and typically relies on mineral-derived silicon chemistry plus petrochemical inputs. It is not considered readily biodegradable and may persist in the environment compared with plant-derived emollients or conditioning agents.
Is Bis-Carboxydecyl Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic because synthetic organosilicon polymers fall outside the allowed material set. It has weak Green Chemistry alignment due to nonrenewable sourcing and limited biodegradability.
How does Bis-Carboxydecyl Dimethicone work chemically?
The molecule is an organosilicon polymer modified with long-chain carboxyl groups, giving it both hydrophobic slip and polar functionality for deposition or emulsification support. It is generally stable across typical cosmetic pH ranges, and performance depends strongly on neutralization state, surfactant system, and emulsifier compatibility.
