Laurdimonium Hydroxypropyl Hydrolyzed Keratin ●
TL;DR. This ingredient is a cationic hair-conditioning agent and film-former. It helps reduce static, improve wet and dry combing, and add a light protein-like feel to hair fibers.
What does Laurdimonium Hydroxypropyl Hydrolyzed Keratin do in a cosmetic formula?
This ingredient is a cationic hair-conditioning agent and film-former. It helps reduce static, improve wet and dry combing, and add a light protein-like feel to hair fibers.
Is Laurdimonium Hydroxypropyl Hydrolyzed Keratin clean?
From a clean-beauty perspective, it has friction because it is a chemically modified animal-derived protein with a permanent cationic charge. It is generally used for rinse-off and hair-care performance rather than skin-care minimalism, and brands may screen for animal sourcing and residual quaternizing reagents.
Is Laurdimonium Hydroxypropyl Hydrolyzed Keratin sustainable?
This material is typically derived from it-rich animal byproducts, often wool or feathers, then chemically modified for better hair affinity. The protein portion is biodegradable, but the cationic modification can increase binding to sludge, sediments, and negatively charged surfaces, which weakens its environmental profile.
Is Laurdimonium Hydroxypropyl Hydrolyzed Keratin COSMOS-approved?
It is not a strong fit for COSMOS-natural or COSMOS-organic formulations because the quaternized modification is outside the usual low-intervention natural-origin profile. From a Green Chemistry view, it uses a renewable byproduct feedstock, but added cationic chemistry and wastewater-binding behavior are compromises.
How does Laurdimonium Hydroxypropyl Hydrolyzed Keratin work chemically?
The molecule is a hydrolyzed protein fragment bearing hydrophobic alkyl and quaternary ammonium functionality, which gives it strong substantivity to the negatively charged surface of damaged hair. It is typically used at low conditioning-active levels in shampoos, conditioners, and treatments, and it is usually compatible with mildly acidic to neutral hair-care systems where cationic deposition is favored.
