Polyglyceryl-4 caprate, also known as Polyglyceryl-4 caprate or Polyglyceryl-4 caprylate, is a synthetic ingredient that is popular in the cosmetic industry for its emulsifying and moisturizing properties. It is an ester of caprylic acid and polyglycerol. This substance is virtually colorless and odorless and is soluble in water and oil, allowing it to act as an effective intermediary between oil and water components in cosmetic products.

Polyglyceryl-4 caprate is widely used in a wide range of cosmetic and personal care products, from facial cleansers and body washes to make-up and hand creams. Its key function is to assist in forming a soft and silky consistency against the skin, while also improving skin hydration. It is also valued for its low irritation, making it a suitable ingredient for sensitive skin. This ester is also often found in hair care products, where it helps deliver moisture and softness without creating a heavy or greasy residue.
