Polyglyceryl-3 Diisostearate, with a CAS number of 63705-03-3, is a thick, transparent liquid that imparts shine and vitality to cosmetics. It is commonly incorporated into lipophilic ointments and sticks to enhance product spreadability, absorbability, and skin softness.
Polyglyceryl-3 Diisostearate is considered a diester (a chemical formed by reacting an acid with two alcohols) of the fatty acid isostearic acid and humectant polyglycerin-3.
Application
1. Non-ionic water-in-oil emulsifier, free of PEG.
2. The emulsification process can be conducted under hot or cold conditions, making it particularly suitable for heat-sensitive or water-soluble active pharmaceutical ingredients (APIs).
3. Oil phase: 15-20%, compatible with vegetable oil, ester, or silicone oil (up to 5%).
4. Stability: Achieved by adding 1-2% NaCl + MgSO4.
Advantages
1. Functions as a lipophilic emulsifier, dispersant, stabilizer, and softener.
2. Exhibits excellent oxidation stability and self-emulsifying power.
3. Demonstrates exceptional makeup removal ability when incorporated into makeup remover oil.
