Ethyl Lauroyl Arginate HCl ●
TL;DR. This ingredient is a cationic antimicrobial preservative used to help control bacteria, yeast, and mold in water-based formulas. It can also contribute mild surfactant or conditioning behavior because the molecule carries a positive charge.
What does Ethyl Lauroyl Arginate HCl do in a cosmetic formula?
This ingredient is a cationic antimicrobial preservative used to help control bacteria, yeast, and mold in water-based formulas. It can also contribute mild surfactant or conditioning behavior because the molecule carries a positive charge.
Is Ethyl Lauroyl Arginate HCl clean?
From a clean-beauty perspective, it is generally viewed as a modern, relatively low-residue preservative option, but it is still a regulated preservative with use limits and category restrictions. The main watchpoint is irritation potential at higher levels, especially around eyes, lips, or mucosal-use products.
Is Ethyl Lauroyl Arginate HCl sustainable?
This material is commonly made from a fatty-acid component that may come from coconut or palm supply chains, paired with an amino-acid-derived component. It is readily biodegradable and is not known for persistence or bioaccumulation concerns.
Is Ethyl Lauroyl Arginate HCl COSMOS-approved?
It is permitted under COSMOS when it meets the standard’s preservative and purity requirements, so it can fit natural and organic-certified formulations under conditions. Its Green Chemistry profile is fairly strong because it can use renewable feedstock elements, works at low levels, and biodegrades, although it is still a chemically synthesized specialty preservative.
How does Ethyl Lauroyl Arginate HCl work chemically?
The molecule is a fatty-acid amino-acid ester salt with cationic surface activity, which helps it interact with microbial membranes. Typical cosmetic use is about 0.05% to 0.4%, with better performance in mildly acidic to neutral systems and reduced compatibility with anionic surfactants, anionic polymers, and high-pH formulas.
