Concentrated surface active compositions

摘要

A low-viscosity concentrated liquid agent modifies the boundary layer characteristics of a liquid in contact with a solid e.g. washing-up liquid or hair shampoo. The concentrate contains esp. 25-55 % by weight amphoteric or dual ion tensides and 0.01 to 5% by weight alkaline sulfates. The concentrate is formulated to 100 per cent with additional water and further electrolyte salts. The formulation incorporate amphoteric or dual ion tensides selected from alkylbetaines, alkyl-amido-betaines, amino-propionates, amino-glycinates, imidazolinium-betaines and sulfo-betaines. The formulation incorporates alkylbetaines having formula (I). R1 = 6-22 C alkyl or alkenyl; R2 = hydrogen or 1-4 C alkyl; R3 = 1-4 C alkyl; q1 = 1-6; and Z = alkali, alkaline earth or ammonium
