What is it?
The PEG Distearate ingredients (PEG-2 Distearate, PEG-3 Distearate, PEG-4 Distearate, PEG-6 Distearate, PEG-8 Distearate, PEG-9 Distearate, PEG-12 Distearate, PEG-20 Distearat, PEG-32 Distearate, PEG-75 Distearate, PEG-120 Distearate, PEG-150 Distearate, PEG-175 Distearate) range from liquids to solids or flakes. In cosmetics and personal care products, PEG Distearate ingredients are used in the formulation of shampoos, hair conditioners, personal cleanliness products, bath products, and skin care and skin cleansing products.
The safety of the PEG Distearate ingredients has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that PEG-2, -3, -4, -6, -8, -9, -12, -20, -32, -75, -120, -150 and -175 Distearate were safe for use in cosmetic formulations.
Why is it used in cosmetics and personal care products?
PEG Distearate ingredients clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away. They also help to form emulsions by reducing the surface tension of the substances to be emulsified and help other ingredients to dissolve in a solvent in which they would not normally dissolve.
Polyethylene Glycol (PEG) Distearates are produced from stearic acid, a naturally occurring fatty acid, which occurs in animal fats and oils. PEG Distearates are manufactured by reacting stearic acid with a specific number of units of ethylene oxide which corresponds to the average PEG chain length desired.
