Abstract
A process for making paper substrates having a soft feel involving: (a) providing a paper substrate; (b) providing an emulsion containing: (i) a polyol poly-12-hydroxystearate; (ii) a wax ester; and (iii) a wax; and (c) impregnating the paper substrate with the emulsion.
Claims27
A process for making paper substrates having a soft feel comprising:
- (a) providing a paper substrate;
- (b) providing an emulsion consisting essentially of:
- (i) about 5 to 25% by weight of a polyol poly-12-hydroxystearate, based on the weight of the emulsion;
- (ii) about 70 to 80% by weight of a wax ester, based on the weight of the emulsion;
- and
- (iii) about 5 to 25% by weight of a wax, based on the weight of the emulsion, said emulsion being of a droplet size effective to uniformly penetrate said paper substrate;
- and
- (c) impregnating the paper substrate with the emulsion, wherein said emulsion penetrates into said paper substrate and is uniformly dispersed therein.
