Compatibility
Works well with:
Glycerin Carbomer Niacinamide Panthenol Sodium Hyaluronate Aloe Vera
Use caution with:
high electrolyte concentrations Borax
HEC is generally broadly compatible across a wide pH range and tolerates most cosmetic actives well. High concentrations of salts or electrolytes can disrupt its hydration and reduce viscosity, so electrolyte levels should be managed carefully. Borax and certain cross-linking agents can cause undesired gelation or precipitation.
Formulation notes
Hydroxyethylcellulose is a non-ionic, water-soluble cellulose ether used primarily as a thickener and rheology modifier in aqueous cosmetic formulations such as gels, lotions, shampoos, and creams. It disperses in cold water but typically requires heating or gradual addition to hydrate fully and develop viscosity. It is considered low sensitization risk and is well tolerated in rinse-off and leave-on products alike.
