TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Properties: The viscosity of the surfactant mixture before adding to SFA, is less than 9500 cps. The viscosity of the composition after adding SFA, is at least 20000 cps, preferably 20000-250000 cps. The self foaming composition has pH of 3-9, preferably 4-7.5.Preferred Composition: The composition comprises at least 10% of the surfactant mixture, 2-30%, preferably 5-20% of anionic surfactant(s), 2-20%, preferably 3-15% of amphoteric surfactant(s), 1-15% of non-ionic surfactant(s), 4-15%, preferably 6-12% of SFA, with respect to the total weight of the composition. The composition is free from ethoxylated fatty alcohols, ethoxylated fatty esters, and thickening agent or viscosity modifiers. SFA comprises 70-90%, preferably 75% of isopentane, and 10-30%, preferably 25% of isobutane, based on the total weight of the agent. The self foaming composition further comprises conditioner(s) such as skin conditioner(s).Preferred Components: The anionic surfactant is alkyl sulfates, alkyl ether sulfates, alkyl monoglyceryl ether sulfates, alkyl monoglyceride sulfates, alkyl monoglyceride sulfonates, alkyl sulfonates, alklaryl sulfonates, alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkyl sulfosuccinamates, alkyl amidosulfosuccinates, alkyl carboxylates, alkyl amidoether carboxylates, alkyl succinates, fatty acyl sarcosinates, fatty acyl amino acids, fatty acyl taurates, fatty alkyl sulfoacetates, alkyl phosphates, and alkyl ether phosphates, preferably sodium laureth sulfate. The amphoteric surfactant is amphocarboxylates, alkyl betaines, amidoalkyl betaines, amidoalkyl sultaines, amphophosphates, phosphobetaines, pyrophosphobetaines, carboxy alkyl alkyl polyamines, alkyl amino monoacetates and alkyl amino diacetates, preferably cocamidopropyl betaine. The non-ionic surfactant is polyoxyethylene derivatives of polyol esters, ethylene oxide/propylene oxide copolymers, (poly)glycerol esters, (poly)glycerol fatty acids, fatty acid alkanolamides, alkoxylated monoalkanolamides, alkoxylated dialkanolamides, amino oxides, ethoxylated fatty alcohols, ethoxylated fatty esters, ethoxylated glucoside and fatty gluconamides, or long chain alkyl glucosides or polyglucosides which are the condensation products of (a) 6-22C long chain alcohol with (b) glucose or glucose containing polymer, preferably decyl glucoside. The alkyl glucoside is octyl glucoside, decyl glucoside and lauryl glucoside. SFA is pentane, isopentane, butane and isobutane. The conditioner is cationic cellulose derivative, cationic guar derivative, or derivatives and copolymers of diallydimethylammonium chloride. The skin conditioner is caprylic capric triglycerides, 12-15C alcohol benzoates, isopropyl palmitate, or glycerine.    TECHNOLOGY FOCUS - POLYMERS - Preferred Package: The self foaming composition is packaged in a barrier system which is a bag inside a can or a piston system. The bag contains an outer polyester layer, middle foil layer and an inner polyethylene or polypropylene layer. EXAMPLE - (In weight%) Water (aqua) (52.2) was heated to 50degreesC, and mixed with ethylene diamine tetra acetic acid (0.1), sodium citrate (0.3) and sodium benzoate (0.5). Then, Texapon N70 (RTM: sodium laureth sulfate) (70%AM) (20), Glucamate DOE 120 (RTM: poly ethylene glycol (PEG-120) methyl glucose dioleate) (1.6), Tegobetaine F50 (RTM: cocamidopropyl betaine) (38%AM) (12), and Plantacare 2000 (RTM: decyl glucoside) (8), were sequentially added, and mixed. The whole mixture was cooled to 30degreesC. Further, Propal (RTM: isopropyl palmitate) (2), Cremophor HR40 (RTM: PEG-40 hydrogenated castor oil) (1), and Neutrofoam perfume givaudan (RTM: fragrance) (1), were added. The pH was adjusted to 5.5 with citric acid (0.3), and the final viscosity of the surfactant mixture was 4400 cps. The surfactant mixture and a self foaming agent (75% isopentane/25% isobutane) were fed through a Pamasol dual piston can filler at a ratio of 92 weight parts (wt.pts) of surfactant mixture to 8 wt.pts of self foaming agent. The can was pressurized with air. The obtained product was a clear, stiff gel, which dispensed from the package into the hand as a soft mound of product without flowing. The gel product, when spread on wet skin, easily sheared to be spread uniformly on the skin during which the gel was transformed to a creamy foam. When rinsing, the foam was easily rinsed from the skin, leaving a soft and moisturized skin feeling.
