Science
Mechanism of Action
This ingredient functions as an emollient by creating a protective, non-occlusive film on the skin's surface, which helps to reduce transepidermal water loss and impart a soft, smooth feel. Concurrently, it aids in emulsification, ensuring the homogeneous dispersion of immiscible liquids within a formulation and preventing their separation over time.

Safety Profile
The CIR Expert Panel concluded that Dimethyl Lauramine Isostearate is safe for use under specific conditions, particularly in non-coloring hair care products. In the European Union, its concentration is limited to a maximum of 2.5% in non-rinse-off products; no limit is set for rinse-off formulations. Crucially, products containing this ingredient must not be exposed to nitrosating systems and require stringent purity standards: a minimum of 99% purity, a maximum secondary amine content of 0.5%, and a maximum nitrosamine content of 50 microg/kg. All packaging must be nitrite-free.
