Stabilisation of emulsions: influence of hydrophilic colloids.
Synopsis The influence of the following hydrophilic polymers on the stability of emulsions has been studied: sodium carboxymethyl cellulose, hydroxyethyl cellulose, agar-agar, water dispersible clay, and a neutralized polyethylene acid. The oil phases used were paraffin oil, olive oil and a synthetic C(8)-C(12) triglyceride. The other emulsifiers were non ionic-types. After 12 months storage at room temperature, olive oil proved to be the most difficult material to emulsify. The hydrocolloids did not give uniformly better stability to the emulsions and the polyacrylic acid gave the best stability of the colloids tested.
