PEG-12 Distearate

PEG-12 Distearate is a synthetic emulsifier derived from polyethylene glycol (PEG) and stearic acid. It belongs to a class of ingredients called polysorbates, which are commonly used in cosmetic and pharmaceutical formulations to stabilise mixtures of water and oil that would otherwise separate.In skincare products, its primary role is to create a stable, uniform texture by allowing water-based and oil-based components to coexist. This allows formulators to create creams, lotions, and serums with a consistent feel and appearance over time.

PEG-12 Distearate works by positioning itself at the boundary between water and oil molecules. One end of the molecule is attracted to water, while the other is attracted to oil. This dual affinity allows it to hold both phases together, preventing them from separating into layers.The ingredient itself does not have direct activity on skin; rather, it is a functional component that enables the delivery and texture of other actives within the formula.

No specific usage guidance applies to this ingredient, as it functions behind the scenes in formulations. Simply use the product as directed on the label. If you have concerns about fungal acne, consider keeping a record of products you use and any skin reactions, which may help identify patterns.

PEG-12 Distearate is generally well-tolerated and has a history of safe use in cosmetics. Those with fungal acne or sensitivity to emulsifiers may wish to patch-test products containing it first.
