Abstract: An improved compound for use as a spray wax and drying aid in automatic vehicle-washing devices. The invention includes an olefin constituent having the general structural formula: ##STR1## wherein R.sub.1 is an alkyl group having between 4 to 28 carbon atoms and a first emulsifier having a cationic constituent. Certain preferred embodiments include a second emulsifier and a coupling agent.
Abstract: A cleaning solvent comprising(A) about 3 to about 20 wt % of a fluorinated compound selected from the group consisting of(1) fluorocarbons having the general formulaC.sub.m H.sub.n F.sub.2m+2-nwhere m is 4 to 8, and n is 0 to m/2 if m is even and 0 to (m+1)/2 if m is odd;(2) C.sub.5 F.sub.11 NO;(3) alkyl perfluoroethers having the general formulaR.sub.1 OR.sub.2where R.sub.1 is C.sub.3 F.sub.7 or C.sub.4 F.sub.9 and R.sub.2 is CH.sub.3 or C.sub.2 H.sub.5 ; and(4) fluorochlorocarbons having the general formulaC.sub.p H.sub.q Cl.sub.r F.sub.2p+2-q-rwhere p is 3, 4, or 5, q is 1 to p-1, and r is 1 to p-1;(B) up to about 15 wt % of a C.sub.1 to C.sub.4 alkanol; and(C) the remainder benzotrifluoride.
Abstract: To replace compositions based on CFC or CFHC in applications for cleaning solid surfaces (in particular defluxing), the invention proposes azeotropic or quasi-azeotropic compositions based on 1,1,1,2,2,4,4-heptafluorobutane and a C.sub.1 -C.sub.3 alcohol.
Abstract: Composition useful as 2-in-1 cleansing products are disclosed that are extremely mild to skin and hair, which use neutralized, essentially chargeless, ionic complexes of fatty amines and fatty acids to deliver various levels of conditioning; neutralized, essentially chargeless, ionic complexes of a detersive surfactant comprising a water soluble cationic surfactant and/or polymer complexed with one or more anionic surfactants; or an amphoteric surfactant complexed with one or more anionic surfactants; or a water soluble cationic surfactant and/or polymer complexed with one or more amphoteric surfactants; or a water soluble cationic surfactant and/or polymer complexed with one or more anionic surfactants and an amphoteric surfactant; detersive surfactant-soluble but water-insoluble silicones or derivatives thereof; and water. These products exhibit true 2-in- conditioning properties, and are lower in cost than current 2 in 1 products. Clear or opacified products can be formulated.
Abstract: A light duty liquid detergent with desirable cleansing properties and mildness to the human skin comprising: a beta-hydroxy paraffin sulfonate surfactant, an alkali metal or ammonium salt of a C.sub.8-18 ethoxylated alkyl ether sulfate anionic surfactant, an amine oxide, an alkyl polyglucoside surfactant, an alkyl C.sub.12 -C.sub.14 monoalkanol amide, an ethoxylated C.sub.12 -C.sub.14 monoalkanol amide and water.
Abstract: Constant boiling azeotropic or azeotrope-like compositions of ammonia and 1,1,1,2-tetrafluoroethane, 1,1,2,2-tetrafluoroethane, difluoromethane, pentafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane are disclosed that are useful as refrigerants, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, expansion agents for polyolefins and polyurethanes and as power cycle working fluids.
