Abstract

The action of sodium chloride, barium chloride, magnesium sulphate, aluminium sulphate, sodium nitrate and sodium sulphate on emulsions containing 1% (w/v) α‐monostearin in water‐white‐ oil and 0·5% (w/v) sodium stearate in water was investigated.

The phase separation curves for the emulsions containing the univalent salts were similar. The emulsions were of the O/W type; the oil separation became very rapid when a certain concentration of salt was reached.

The bi‐ and tervalent salts caused phase inversion of the emulsions and precipitation of (some of) the emulsifying agents.

The action of p~H~ on the emulsions was also investigated. The stability of the emulsions decreased with decreasing p~H~ values and the structure of the emulsions became complex; at higher P~H~ values however, very mobile and stable O/W emulsions were obtained.
