Science
Mechanism of Action
This anionic lipo-amino acid functions by lowering the surface tension of water to lift oils and impurities without disrupting the skin's delicate acid mantle. Because its structure is highly biocompatible with skin proteins, it preserves the hydrolipidic film and provides integrated conditioning benefits during the cleansing process.

Key findings
- 01 Clinical evaluations of related acylated amino acids at concentrations of 7.38% demonstrate a total lack of dermal irritation or sensitization in human subjects.
- 02 Safety assessments for leave-on applications at 0.65% support a high tolerance profile for products requiring prolonged skin contact, such as foundations and sprays.
Transparency
Dusting Analysis
In cleansing formulations, concentrations below 1% may indicate the ingredient is being used primarily for marketing claims rather than functional surfactant performance. However, it remains safe and beneficial for conditioning at lower levels in leave-on products.
The Formula
Formulation
Stability
Maintains stability across acidic and neutral ranges; however, peak foaming aesthetics and structural integrity are best achieved between pH 5.5 and 7.0.
Synergies
- Non-ionic surfactants
- Amphoteric surfactants
- Glycerin
- Hyaluronic acid
Conflicts
- High concentrations of cationic surfactants (potential complex formation)
- Strongly alkaline environments (potential for long-term hydrolysis)
Safety
Safety Profile
Recognized as safe for rinse-off applications up to 40% and leave-on applications typically formulated under 5%.
