Question 1

What does Peg/Ppg-22/24 Dimethicone do in a cosmetic formula?

Accepted Answer

This ingredient is a nonionic emulsifier, spreading agent, and conditioning aid, often used to help oil, water, and pigment phases disperse more evenly. It can also improve slip and reduce tack in skin care, makeup, hair care, and antiperspirant formulas.

Question 2

Is Peg/Ppg-22/24 Dimethicone clean?

Accepted Answer

From a clean-beauty perspective, this material has friction because it is a synthetic polymer made with ethoxylated and propoxylated segments, where residual impurities such as 1,4-dioxane can be a concern if purification is not well controlled. It is generally low-irritation on skin, but its restricted-list status is often driven by sourcing, processing, and environmental profile rather than acute skin tolerance.

Question 3

Is Peg/Ppg-22/24 Dimethicone sustainable?

Accepted Answer

This material is typically petrochemical-derived and not readily biodegradable. Its polymeric structure raises persistence concerns in wastewater and the wider environment, even though it is used at relatively low levels in finished products.

Question 4

Is Peg/Ppg-22/24 Dimethicone COSMOS-approved?

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic standards. Its fit with Green Chemistry is weak because it relies on non-renewable feedstocks, energy-intensive synthetic modification, and limited biodegradability.

Question 5

How does Peg/Ppg-22/24 Dimethicone work chemically?

Accepted Answer

The molecule is an amphiphilic synthetic polymer with a hydrophobic flexible backbone and water-compatible ethoxylated and propoxylated side chains, which gives it interfacial activity and slip. It is commonly used at low single-digit percentages, remains broadly stable across typical cosmetic pH ranges, and is usually selected to improve emulsification, pigment wetting, or sensory feel rather than preservation or active delivery.
