Carboxylic acids and salts having alkyl chains longer than eight carbons exhibit unusual behavior in water due to the presence of both hydrophilic (CO2) and hydrophobic (alkyl) regions in the same molecule. Freshen Dresser Drawers, Closets, Suitcases, and Cars. To make a solid soap N a O H is used, while K O H is used for liquid soaps. Liquid Crothix can be used to thicken products like shampoos, bath gels, or liquid soaps, simply by preheating the material to a temperature above 50C and then adding it to the cold surfactant base with mixing. It readily absorbs water and forms aqueous solutions. The difference between solid and liquid . They contain natural saponins. Cationic detergents often exhibit germicidal properties, and their ability to change surface pH has made them useful as fabric softeners and hair conditioners.
