ABSTRACT:
Petrolatum fractions in which to a large extent no white oils are present are combined with a volatile siloxane, hexamethyldisiloxane, octamethylcyclotetrasiloxane and/or decamethylcyclopentasiloxane to provide an ointment base which enables these petrolatum fractions to be spread easily on the skin. Evaporation of the solvent leaves a vaseline film on the skin that is nonirritating and yet highly resistive to washing away. A high melting microcrystalline wax as an additive can reduce the lustre of the film. Lower alcohols can also be added to make spreading still easier.
