C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate ●
TL;DR. This ingredient is primarily a cationic conditioning agent and antistatic agent, used to improve wet combing, softness, and deposition on hair fibers. It can also support emulsification in conditioner systems.
What does C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate do in a cosmetic formula?
This ingredient is primarily a cationic conditioning agent and antistatic agent, used to improve wet combing, softness, and deposition on hair fibers. It can also support emulsification in conditioner systems.
Is C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic quaternary ammonium compound, a class often flagged for aquatic concerns and skin or eye irritation at higher use levels. It may appear on restricted lists or be excluded by stricter standards, especially for products positioned as readily biodegradable or natural-origin.
Is C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate sustainable?
This material is typically made from petrochemical and fatty-derived feedstocks, with chain lengths that may come from mixed natural or synthetic sources. Quaternary ammonium conditioning agents can have slower biodegradation and higher aquatic adsorption than simpler fatty alcohols or plant oils.
Is C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate COSMOS-approved?
This ingredient is not generally aligned with COSMOS-natural or COSMOS-organic standards because of its synthetic quaternary ammonium chemistry. Its fit with Green Chemistry is limited by persistence concerns, cationic aquatic activity, and reliance on conventional quaternization chemistry.
How does C10-40 Isoalkylamidopropyl-Ethyldimonium Ethosulfate work chemically?
The molecule is a permanently charged quaternary ammonium salt with long branched alkyl groups, an amide linker, and an it counterion, which gives strong attraction to negatively charged hair surfaces. It is usually formulated at low active levels in rinse-off conditioning systems, is broadly pH-stable, and is generally incompatible with strongly anionic surfactants because ion-pairing can reduce performance or cause precipitation.
