About this ingredient
PEG-14M is a high-molecular-weight polymer used as a thickener. It raises the viscosity of the water phase, stabilises the formula and gives a smooth, pleasant texture that applies without greasiness. This is a functional texture ingredient, not a skincare active. It does not fix wrinkles or pigment; its use is to add body, suspend ingredients and improve the slip of the product. The thickening role is well established in formulation. Applied topically there is no meaningful systemic absorption, so it can be used during pregnancy and breastfeeding. Tolerance is good: low irritation and allergy potential, compatible with sensitive skin. It is an inert polymer with no fragrance or reactive groups, so skin reactions are unlikely even on reactive skin.
