Polyglyceryl-2 Stearate

Polyglyceryl-2 Stearate is a non-ionic emulsifier/skin-conditioning agent typically used at low-to-moderate levels (~1–5%) to stabilize oil-water mixtures, and it is generally well tolerated in repeat-use and patch-test experience. True irritation is uncommon, but in severely compromised barriers (eczema flares, post-procedure skin) any surfactant-like emulsifier can contribute to stinging or dryness in a minority of highly reactive individuals. Given its overall low inherent irritancy yet non-zero risk in compromised skin, it fits best as very gentle rather than inert. Safety Notes: Polyglyceryl-2 Stearate is used as a nonionic emulsifier/co-emulsifier and emollient, and in many consumer leave-on lotions/creams it appears at low supportive levels around 0.1–1% (often alongside stronger primary emulsifier systems). In richer leave-on creams, cleansing creams/balms, and high-oil anhydrous-to-emulsifying systems marketed to consumers, it is commonly used at ~2–6% and can be pushed to about 10–12% in high-structure specialty formulations where it functions as a major emulsifier/texture builder; rinse-off products tend to sit in the lower-to-mid part of this range due to cost and sensory targets.
