In plain English

Polyglyceryl-20 Heptacaprylate is a gentle emulsifier made from glycerin and caprylic acid (a fatty acid from coconut or palm oil). Its job is to help water and oil mix together so your moisturizer or serum stays smooth and doesn't separate. It's considered very mild and unlikely to cause irritation or breakouts, making it a popular choice for sensitive and acne-prone skin.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic emulsifier derived from glycerin and caprylic acid, designed to stabilize oil-in-water emulsions.

How it works

It reduces the surface tension between oil and water, allowing them to blend into a stable, creamy texture. This helps skincare products feel smooth and spread easily on the skin.

Pros

Gentle on skin

Polyglyceryl-20 Heptacaprylate has a very low irritation risk, making it ideal for sensitive or reactive skin types.

Non-comedogenic
