PEG-4 Laurate
What is PEG-4 Laurate?
PEG-4 Laurate is a synthetic ingredient formed by esterifying lauric acid, a saturated fatty acid typically sourced from coconut or palm kernel oil, with polyethylene glycol (PEG-4). This creates a versatile nonionic surfactant commonly used in rinse-off and leave-on cosmetics like shampoos, body washes, facial cleansers, lotions, and creams. In formulations, it functions by lowering surface tension between oil and water phases, enabling effective cleansing through dirt and oil removal while stabilizing emulsions for smooth, uniform textures. Its hydrophilic-lipophilic balance supports micelle formation, which traps impurities for easy rinsing. As an emulsifying agent, it forms protective films at interfaces, preventing phase separation and enhancing product spreadability and feel on skin. Regulatory bodies like the Cosmetic Ingredient Review have assessed PEG laurates as safe in typical concentrations, with low irritation potential in cosmetic applications.

Who It's For
A quick guide for who this ingredient may suit (and who should be cautious).
| Who May Benefit | Who Should Avoid |
|---|---|
| Individuals seeking effective yet gentle cleansers for daily use. | Those preferring PEG-free formulations due to sensitivity concerns. |
| People with non-comedogenic needs, as it has low pore-clogging potential. | People with known allergies to lauric acid derivatives. |
| Users of emulsified products like moisturizers wanting smooth application. | Individuals avoiding ethoxylated ingredients on principle. |
Safety Notes
- Rated low to moderate concern by hazard assessments like EWG (2-4), indicating general safety in cosmetics.
- Potential for impurities like ethylene oxide if not purified, but regulated standards minimize risks.
