Polyglyceryl-2 Stearate

What Polyglyceryl-2 Stearate is & what it does

Polyglyceryl-2 Stearate is a non-ionic emulsifier made by combining stearic acid (a fatty acid) with polyglycerin derived from glycerin. In a skincare or sunscreen formula it helps bind oil and water phases into a stable cream or lotion and contributes to a smooth, conditioned skin feel. It is a popular choice in "PEG-free" and naturally derived formulas because it is mild and produces a soft, non-greasy texture.

Is Polyglyceryl-2 Stearate safe?

Polyglyceryl-2 Stearate is widely used as a non-ionic emulsifier in cosmetics and is generally regarded as gentle and well tolerated on the skin. It is a common choice in mild, fragrance-free, and naturally derived formulas. As with any ingredient, people with very sensitive skin should patch test a new product first.

Is Polyglyceryl-2 Stearate comedogenic?

Polyglyceryl-2 Stearate is generally considered low on the comedogenic scale and is not typically flagged as a major pore-clogging ingredient. Because it is derived from stearic acid, individual reactions can vary, especially in very acne-prone skin. Whether a finished product clogs pores depends on the whole formula, not this single emulsifier.

Is Polyglyceryl-2 Stearate vegan?

Polyglyceryl-2 Stearate is made from glycerin and stearic acid, both of which can come from either plant or animal sources. Many suppliers today use plant-derived (often vegetable oil) raw materials, making vegan versions common. If vegan status matters, check for a brand or supplier claim, since the source is not guaranteed by the INCI name alone.
