- Solvent for essential oils; better humectancy than PEG
- Olive Oil Peg-7 Esters
- Olive oil PEG-7 esters, gentle emulsifier and emollient containing PEG structure; suitable for creams, monitor PEG allergens and contamination.
- Peg-60 Hydrogenated Castor Oil
- Non-ionic emulsifier and solubilizer at 1–5%; contains PEG, check acid compatibility and sensitive skin irritation
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Peg-7 Glyceryl Cocoate
- PEG-modified nonionic surfactant for emulsification and cleansing; contains PEG, monitor dioxane, low comedogenicity.
