Abstract: A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.

Abstract: The invention relates to a process for preparing products containing polymer chains in which a linear prepolymer or polymer contains at least one free acid group at each chain and is reacted with an alkoxide of a metal having a valence of more than 2, such as zirconium, titanium or cerium, possibly in the presence of a non polar solvent, the alkoxide of the metal having a valence of more than 2 being used in such a quantity that the alkoxide functions are in excess with respect to the stoichiometric amount of the acid functions carried by said linear prepolymer or polymer, the reaction mixture being stirred in the presence of humidity until a product is obtained wherein the hydrogen atoms of the free acid end groups of the prepolymer or polymer are substituted by an atom of the metal (M) which is itself linked to another atom of said metal by M-O-M linkages. The invention relates also to the products containing a prepolymer or polymer .alpha.,.omega.

Abstract: Viscous, homogeneous and thermoreversible gels containing polymer chains are obtained by a process in which a solution of a prepolymer or polymer which contains at least one free acid group at each chain end in a non polar solvent selected among the aliphatic, alicyclic and aromatic hydrocarbons having a dielectric constant of less than about 3 is reacted at room temperature with a stoechiometric amount, based on the acid group content of the polymer, of a metal aliphatic alkoxide so as to neutralize all the free acid groups and a sufficient amount of the non polar solvent is distilled for removing, in a substantially quantitative manner, the aliphatic alcohol formed by said reaction.
