PEG-12 Dilaurate

PEG-12 Dilaurate is a nonionic surfactant derived from polyethylene glycol (PEG) and lauric acid, a naturally occurring fatty acid. It functions as an emulsifier, meaning it helps stabilise mixtures of water and oil-based ingredients that would normally separate, allowing formulators to create smooth, uniform textures in creams, serums and lotions.The ingredient is widely used across the cosmetics industry because it is effective at low concentrations and generally well-tolerated by skin. Its chemical structure—a short PEG chain paired with a moderate-length fatty acid—gives it the right ba…

PEG-12 Dilaurate works at the molecular level by positioning itself at the boundary between water and oil phases in a formula. One end of the molecule is attracted to water, whilst the other is attracted to oil. This dual affinity allows it to hold these normally incompatible phases together in a stable emulsion, preventing separation and maintaining the product's integrity from manufacture to use.Because it is a mild, nonionic surfactant (meaning it carries no electrical charge), it is gentler on skin than more aggressive emulsifying agents, making it suitable for use in leave-on skincare …

PEG-12 Dilaurate is a behind-the-scenes ingredient that does not require special usage instructions from the consumer. It is present in formulations at concentrations determined by the manufacturer to achieve the desired texture and stability. You simply apply the finished product as directed.

PEG-12 Dilaurate is generally well-tolerated and is approved for use in cosmetics across major regulatory regions. It is unlikely to cause irritation in most skin types, though those with very sensitive skin or known surfactant sensitivities should patch-test products containing it.
