Stearamidopropyl ●
TL;DR. This ingredient is primarily a hair-conditioning and antistatic agent. It adsorbs to the hair fiber, improving slip, wet combing, softness, and frizz control, especially in conditioners and conditioning cleansers.
What does Stearamidopropyl do in a cosmetic formula?
This ingredient is primarily a hair-conditioning and antistatic agent. It adsorbs to the hair fiber, improving slip, wet combing, softness, and frizz control, especially in conditioners and conditioning cleansers.
Is Stearamidopropyl clean?
From a clean-beauty perspective, this ingredient is usually acceptable when well purified and used at low levels, but it carries some friction because free amine residues can increase eye or skin irritation potential. It is most common in rinse-off hair care, where exposure is limited and formulation pH helps control mildness.
Is Stearamidopropyl sustainable?
This material is commonly made from a long-chain fatty acid source, often palm, other vegetable oils, or tallow, combined with an amine-based building block. The fatty portion is generally biodegradable, but sourcing traceability and palm certification are the main sustainability questions.
Is Stearamidopropyl COSMOS-approved?
COSMOS alignment depends on the exact commercial grade and feedstock. Plant-derived grades made through permitted fatty-acid amidation chemistry can fit COSMOS-natural logic, while grades using non-compliant sourcing or processing may not qualify.
How does Stearamidopropyl work chemically?
The molecule is a C18 fatty amide with a propyl amine group, giving it both oil-compatible and water-interactive character. It is commonly used around 0.1% to 2% in hair conditioners, performs best below neutral pH when the amine is protonated, and is often paired with organic acids and fatty alcohols for deposition and viscosity.
