Stearamido-Propyl Dimethylamine ●
TL;DR. This ingredient is a cationic conditioning agent and emulsifying aid used mainly in hair conditioners and masks. After acid neutralization, it improves wet combing, softness, and static control while helping fatty alcohol systems form a stable cream structure.
What does Stearamido-Propyl Dimethylamine do in a cosmetic formula?
This ingredient is a cationic conditioning agent and emulsifying aid used mainly in hair conditioners and masks. After acid neutralization, it improves wet combing, softness, and static control while helping fatty alcohol systems form a stable cream structure.
Is Stearamido-Propyl Dimethylamine clean?
Clean frameworks often view it as a milder alternative to permanent quaternary conditioners, but it still needs pH control and low residual amine impurities for good tolerance. It is not a common fragrance allergen or formaldehyde donor, and irritation risk is mainly tied to concentration, incomplete neutralization, or impurity quality.
Is Stearamido-Propyl Dimethylamine sustainable?
This material is usually built from long-chain fatty acids from vegetable oils, often palm or rapeseed, plus synthetic amine chemistry. It is generally biodegradable and less persistent than many silicone or permanent quat conditioners, but responsible fatty-acid sourcing matters.
Is Stearamido-Propyl Dimethylamine COSMOS-approved?
It is generally accepted for COSMOS-natural and COSMOS-organic products when the grade meets the standard’s feedstock and impurity documentation, and suppliers commonly offer certified-approved grades. Its Green Chemistry fit is moderate to good: renewable fatty feedstocks and biodegradability are positives, while amine synthesis and possible palm dependence keep it from being a more straightforward natural material.
How does Stearamido-Propyl Dimethylamine work chemically?
The molecule is a fatty amidoamine, with a C18 hydrophobe linked through an amide to a tertiary amine that becomes cationic when protonated. Typical use is about 0.5–2% active in rinse-off conditioners, neutralized with lactic or citric acid to roughly pH 4–5.5 and paired with fatty alcohols for deposition and viscosity.
