Ethylhexylglycerin Octoxyglycerin 3-(2-ethylhexyloxy)propane-1,2-diol 3-[(2-Ethylhexyl)oxy]-1,2-propanediol 3-((2-ethylhexyl)oxy)-1,2-propanediol RefChem:57651 Ethylhexylglycerin 0.5% 3-[2-(Ethylhexyl)oxyl]-1,2-propandiol 3-(2-ethylhexoxy)propane-1,2-diol 3-((2-Ethylhexyl)oxy)propane-1,2-diol 3-(2-ethylhexyloxy)-1,2-propanediol 3-[(2-ethylhexyl)oxy]propane-1,2-diol
Compatibility
Works well with:
Phenoxyethanol Caprylyl Glycol Benzyl Alcohol Sodium Benzoate Potassium Sorbate Glycerin Niacinamide Hyaluronic Acid Carbomer Xanthan Gum
Use caution with:
High-concentration cationic surfactants Quaternary Ammonium Compounds
Ethylhexylglycerin is most commonly used as a preservative booster in combination with Phenoxyethanol, allowing reduced concentrations of each. It can interact with high levels of cationic ingredients, potentially reducing efficacy. It is broadly compatible with most cosmetic systems across a wide pH range.
Formulation notes
Primarily used as a preservative booster rather than a standalone preservative; typical synergistic blend is 0.9% Phenoxyethanol + 0.1% Ethylhexylglycerin. Maximum use level in leave-on products is generally considered 1.0%. Well-tolerated, low sensitization potential, suitable for rinse-off and leave-on applications.
