About
A large-molecule ethoxylated and propoxylated alcohol surfactant used as a solubilizer and emulsifier, with low irritation and no EU restrictions.
PPG-4 C13-15 PARETH-15 is a non-ionic surfactant resulting from the ethoxylation and propoxylation of a C13-15 synthetic alcohol blend, with an average of 15 moles EO and 4 moles PO. The relatively high EO number and substantial carbon chain produce a large molecular weight that poorly penetrates skin, making it one of the gentler solubilizers available. It is not subject to restriction under EU cosmetic Regulation 1223/2009.
Skin benefits
- Effective solubilizer for fragrances and oils
- Mild co-surfactant in cleansing products
- Stable across a wide pH range
Known concerns
- Potential for trace residual monomers
- Not suitable for eye-area formulations at high concentrations
