ABSTRACT:
Natural or synthetic wax dissolved in the continuous organic phase of an water-in-oil emulsion retards evaporation of water from a dispersed aqueous phase. An in situ prepared equilibrium mixture of benzyl alcohol, formic acid and benzyl formate emulsified with oleic hydroxyethyl imidazoline or similar oil soluble emulsifying agent is thickened with hydroxypropyl cellulose or hydroxypropyl methylcellulose and contains 0.1 to 1.0% by weight paraffin wax with a melting point of 47.degree. to 65.degree. C. Wax dissolved in the organic phase retards evaporation of water, and formic acid or ammonia which are very volatile in comparison with benzyl alcohol forming the major component of the organic phase. A petroleum distillate is used to pre-wet a hydroxypropyl cellulose thickener and dissolve the wax.
