12 Solubilizing properties AMIDET N vs commonly used non-ionic solubilizers %w/w of solubilizer required to solubilize 1% of cosmetic oils Cosmetic Oils AMIDET N Polysorbate-20 PEG-40 Hydrogenated Castor Oil Olive oil 5 >10 5 Jojoba oil 10 >10 5 Isopropyl Myristate Mineral Oil 10 >10 5 Cold-processable Hot-processable AMIDET N performs better than Polysorbate-20 and similar than PEG-40 Hydrogenated Castor Oil but with the advantage of the cold processing

13 Solubilizing properties Synergistic combination between AMIDET N and PEG-40 Hydrogenated Castor Oil 12:7:1 AMIDET N : PEG-40 Hydrogenated Castor Oil : Water Solubilizer 0.5% Jojoba Oil 2% Jojoba Oil PEG-40 H Castor Oil Turbid White AMIDET N Turbid White Blend Clear Clear These formulations have good foamability and good skin-care properties.

14 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: 3:1:1 Silicone : AMIDET N : Water This blend is a clear viscous gel, easily incorporated into formulations at room temperature.
