AMIDET® N as Liquid Co-emulsifier

Due to its emulsifying properties in O/W systems, AMIDET N can

help to incorporate dimethicones efficiently into formulations.

The best combination to emulsify silicones is:

This blend is a clear viscous gel, easily

incorporated into formulations at room

temperature.
