Abstract
A paper towel includes: (a) a cellulosic towel web; and (b) a lotion emulsion disposed on the towel web. The lotion emulsion is substantially liquid at room temperature and includes a polar emollient and a non-polar emollient as well as a surfactant composition comprising a nonionic surfactant; wherein the emollients and surfactant composition are selected such that the lotion emulsion is immobilized on the towel web in a semi-solid or solid state and the lotion emulsion is capable of forming an aqueous gel upon contact with water. Preferably, the lotion emulsion is a waterless micro-emulsion which is also capable of forming an aqueous micro-emulsion with water.
Claims32
A lotion-treated substrate suitable for tissue or towel comprising:
- (a) a cellulosic web;
- and
- (b) a lotion emulsion disposed on the web,
- the lotion emulsion including a polar emollient and a non-polar emollient as well as a surfactant composition comprising a nonionic surfactant, the polar emollient, nonpolar emollient and surfactant composition being selected so as to be capable of forming a micro-emulsion in the absence of water;
- (c) wherein the lotion emulsion is liquid at room temperature;
- (d) the emollients and surfactant composition are selected such that the lotion emulsion is a stabilized micro-emulsion which undergoes a phase change to a semi-solid or solid upon contact with the fibers of the web and is thus immobilized on the web in a semi-solid or solid state;
- and
- (e) wherein the lotion emulsion is capable of forming an aqueous gel upon contact with water.
A lotion-treated substrate suitable for tissue or towel comprising:
- (a) a cellulosic web;
- (b) a waterless micro-emulsion which is liquid at room temperature and undergoes a phase change to a semi-solid or solid upon contact with the fibers of the web and is thus immobilized on the web in a semi-solid or solid state;
- (c) wherein the waterless micro-emulsion is a stabilized micro-emulsion which consists essentially of a polar emollient, a non-polar emollient and a surfactant composition comprising a nonionic surfactant;
- and
- (d) wherein further the waterless micro-emulsion is capable of forming an aqueous gel upon contact with water.
A lotion-treated substrate suitable for tissue or towel comprising:
- (a) a cellulosic web;
- and
- (b) a waterless micro-emulsion which is liquid at room temperature and undergoes a phase change to a semi-solid or solid upon contact with the fibers of the web and is thus immobilized on the web in a semi-solid or a solid state;
- wherein the micro-emulsion is a stabilized micro-emulsion which comprises a polar emollient, a non-polar emollient, a co-surfactant and a non-ionic surfactant.
A method of making a lotion-treated substrate suitable for tissue or towel comprising:
- (a) preparing a lotion emulsion including a polar emollient and a non-polar emollient as well as a surfactant composition comprising a nonionic surfactant, the polar emollient, nonpolar emollient and surfactant composition being selected so as to be capable of forming a micro-emulsion in the absence of water;
- (b) treating a cellulosic web with the lotion emulsion;
- wherein the emollient composition and surfactant composition are further characterized such that the lotion emulsion is a stabilized micro-emulsion which undergoes a phase change to a semi-solid or solid upon contact with the fibers of the web and is thus immobilized on the towel web in a semi-solid or solid state and wherein the lotion emulsion is capable of forming an aqueous gel upon contact with water.
A lotion-treated substrate suitable for tissue or towel comprising:

- the lotion emulsion including a polar emollient and a non-polar emollient as well as a surfactant composition comprising a nonionic surfactant, the polar emollient, nonpolar emollient and surfactant composition being selected so as to be capable of forming a micro-emulsion in the absence of water;
- (c) wherein the lotion emulsion is liquid at room temperature;
- (d) the emollients and surfactant composition are selected such that the lotion emulsion is a stabilized micro-emulsion which undergoes a phase change to a semi-solid or solid upon contact with the fibers of the web and is thus immobilized on the web in a semi-solid or solid state;
- and
- (e) wherein the lotion emulsion is capable of forming an aqueous gel upon contact with a sufficient amount of water;
- and
- (f) wherein further the lotion emulsion is also capable of forming a micro-emulsion in the presence of water in an amount less than required for gellation.
