Betaine 1% ●
TL;DR. This ingredient functions mainly as a water-binding humectant and skin-conditioning osmolyte. At 1%, it helps improve hydration feel and can soften the sensory profile of surfactant-based formulas.
What does Betaine 1% do in a cosmetic formula?
This ingredient functions mainly as a water-binding humectant and skin-conditioning osmolyte. At 1%, it helps improve hydration feel and can soften the sensory profile of surfactant-based formulas.
Is Betaine 1% clean?
It is generally well tolerated, low in irritation potential, and not a common clean-standard restricted-list concern. It is often viewed as an uncomplicated hydration-support ingredient rather than a controversial active.
Is Betaine 1% sustainable?
This material is commonly sourced from plant-derived sugar streams, especially beet processing byproducts, though synthetic routes also exist. It is water soluble and generally considered readily biodegradable, with low persistence concerns.
Is Betaine 1% COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the source and processing route meet standard requirements. From a Green Chemistry view, plant sourcing, water compatibility, and good biodegradability give it strong alignment.
How does Betaine 1% work chemically?
The molecule is a small zwitterionic amino-acid-derived osmolyte with both a positively charged ammonium center and a negatively charged carboxylate group, which supports water interaction and protein-stabilizing behavior. Typical cosmetic use is about 0.5% to 5%, and it is broadly pH compatible, water soluble, and stable in rinse-off and leave-on systems.
