| abstract |
The invention concerns amphoteric amphiphilic compounds with at least two hydrophilic groups and at least two hydrophobic groups, the molecule being made up of two complete surfactant units bound to each other. The compounds can be combined with all current anionic, non-anionic, cationic and ampholytic surface-active agents. The amphoteric amphiphilic surface-active compounds described are particularly suitable for use as emulsifiers, anti-foaming agents, detergents, dispersants and hydrotropic agents in industry and in the home, for instance in the metalworking field, in ore extraction, in the washing and cleaning of textiles, hard surfaces, the skin and the hair, and in cosmetics. |
