Disclosed are personal care formulations, personal care methods and personal care devices that comprise or use a gel, lotion, cream or the like comprising (a) one or more active ingredients for providing a beneficial effect to the skin and/or hair and/or mucous membranes of a human and (b) from about 1 percent by weight to about 50 percent by weight of foam forming component(s) comprising trans-1-chloro-3,3,3-trifluoropropene (1233zd(E).
Claims17
A method of treating human skin, hair and/or mucous membranes comprising:
- (a) providing a personal care composition in the form of a gel, lotion or cream comprising:
- (i) one or more active ingredients;
- (ii) optionally one or more auxiliary gel, lotion or cream forming components;
- and (iii) foam forming component(s) present in an amount of from about 30 percent by weight to about 50 percent by weight based on the total weight of the components (i), (ii) and (iii), said foam forming component(s) comprising:
- (1) at least about 90 percent by weight, based on the total of components (1) and (2), of trans-1-chloro-3,3,3-trifluoropropene (1233zd(E));
- (b) spreading said gel, lotion or cream on and/or into the skin, hair and/or mucous membrane of the human being treated;
- and
- (c) foaming said gel, lotion or cream during delivery and/or while in contact with the skin, hair and/or mucous membrane by evaporating said trans-1-chloro-3,3,3-trifluoropropene (1233zd(E)) from said gel, lotion or cream.
A personal care formulation for treating human skin, hair and/or mucous membranes comprising a gel, lotion or cream comprising:
- (a) one or more active ingredients for providing a beneficial effect to the skin and/or hair and/or mucous membranes of a human,
- (b) optionally one or more auxiliary gel, lotion or cream forming components, and
- (c) from about 1 percent by weight to about 50 percent by weight based on the total of components (a), (b) and (c) of foam forming component(s), wherein said foam forming component comprises at least about 90% by weight of trans-1-chloro-3,3,3-trifluoropropene (1233zd(E).
A method of treating human skin, hair and/or mucous membranes with a personal care gel, lotion, cream or foam, said method comprising:
- (a) providing a closed container openable to dispensing the contents thereof and including therein a personal care formulation in the form of an emulsion and/or dispersion comprising:
- (i) one or more active ingredients for providing a beneficial effect to the skin and/or hair of a human,
- (ii) optionally one or more auxiliary gel, lotion, or cream forming components,
- (iii) foam forming component(s) present in an amount of from about 30 percent by weight to about 50 percent by weight based on the total weight of the components (1), (ii) and (iii), said foam forming component(s) comprising:
- (1) at least about 90 percent by weight, based on the total of components (1) and (2), of trans-1-chloro-3,3,3-trifluoropropene (1233zd(E);
- and optionally
- (2) a co-foaming agent different than said 1233zd(E);
- and
- (iv) an external propellant for providing a force tending to eject said personal care composition from said container,
- (b) dispensing said personal care formulation from said container by propelling said personal care formulation from said container;
- (c) applying said dispensed personal care formulation to the skin, hair and/or mucous membranes;
- and
- (d) providing a cooling sensation to the human being treated by evaporating at least a portion said trans-1-chloro-3,3,3-trifluoropropene (1233zd(E)) from said applied personal care composition after said dispensing step.
