Trideceth-9 PG-Amodimethicone ●
TL;DR. This ingredient is a hair-conditioning and film-forming agent that improves slip, detangling, frizz control, and shine. It is designed to deposit preferentially on damaged, negatively charged hair fibers.
What does Trideceth-9 PG-Amodimethicone do in a cosmetic formula?
This ingredient is a hair-conditioning and film-forming agent that improves slip, detangling, frizz control, and shine. It is designed to deposit preferentially on damaged, negatively charged hair fibers.
Is Trideceth-9 PG-Amodimethicone clean?
From a clean-beauty perspective, this material has friction because it is a synthetic silicone-derived polymer with ethoxylated chemistry. Well-purified grades are typically low-irritation, but residual ethoxylation byproducts are a common screening point.
Is Trideceth-9 PG-Amodimethicone sustainable?
This material is mainly synthetic, drawing on silicon-based and petrochemical feedstocks. It is not readily biodegradable, and wastewater removal is expected to rely more on adsorption to sludge than rapid breakdown.
Is Trideceth-9 PG-Amodimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because of its synthetic silicone-based structure and petrochemical ethoxylated portion. Its persistence and limited renewable content make it a weak fit with Green Chemistry priorities.
How does Trideceth-9 PG-Amodimethicone work chemically?
The molecule is an organosiloxane conditioning polymer modified with polyether and amine-functional groups, which supports water dispersibility and targeted deposition onto damaged hair. It is commonly used in rinse-off hair care at low levels within surfactant systems, where compatibility with anionic cleansers and pH control affect deposition and feel.
