Science

Mechanism of Action

This ingredient functions by significantly lowering surface tension at the water-oil interface, which is fundamental to its surfactant properties. This action facilitates the formation of stable emulsions and promotes rich, stable foam generation for effective cleansing. It is specifically recognized for its mild interaction with the skin.

Max tested
20%
Sensitization risk Low

The CIR Expert Panel assessed the safety of 11 fatty amphocarboxylates, including Disodium Cocoamphodiacetate (a very close analogue), concluding they are safe in cosmetics when formulated to be non-sensitizing. Disodium Cocoamphodiacetate was previously reviewed in 1990 and re-affirmed as safe in 2008. The highest reported concentration for the analogue Disodium Cocoamphodiacetate is up to 20% in rinse-off cleansing products, while another analogue, Disodium Lauroamphodiacetate, is reported up to 5.4% in leave-on products. No specific SCCS opinion exists, and it is not listed as prohibited or restricted by the FDA for cosmetic use.
