About
A shorter-chain methoxy PEG that acts as a lightweight humectant — hydrates without heaviness, making it great for lightweight serums and gels.
Methoxy PEG-10 is a methyl-capped polyethylene glycol with an average of 10 ethylene oxide units. The shorter chain makes it less viscous and more mobile than higher-molecular-weight methoxy PEGs, while still providing humectant and skin-conditioning properties. It is listed in CosIng with no restrictions. The favorable safety profile of PEG ethers of this size is well-documented in toxicological literature.
