Personal care compositions and methods comprising trans-1-chloro-3,3,3-trifluoropropene and trans-1,3,3,3-tetrafluoropropene

A methods of treating human skin, hair and/or mucous membranes comprising:

• (a) providing a personal care composition in a contamer under pressure in the form of a stable oil-m-water emulsion comprising:
• (i) a continuous aqueous phase comprising water;
• (ii) a discontinuous phase comprising foam forming component(s), trans-1-chloro-3,3,3-trifluoropropene (1233zd(E)) and trans-1-3,3,3-tetrafluoropropene (1234ze(E)), wherein said 1233zd(E) and said 1234ze(E) together comprise from about 40% to about 60% by weight of said personal care composition and are present in a trans1233zd:trans1234ze weight ratio of from about 8:1 to about 8:1;
• (iii) an emulsifier having an HLB value of from about 7 to about 18 and which may be present in the continuous and/or discontinuous phase;
• (iv) one or more active ingredients which may be present in the continuous and/or discontinuous phase;
• and
• (v) optionally one or more auxiliary gel, lotion or cream forming components which may be present in the continuous and/or discontinuous phase;
• (b) dispensing said personal care composition on and/or into the skin, hair and/or mucous membrane of the human being treated by discharging at least a portion of the personal care composition from said container into ambient pressure conditions to form a foam.
