(57) Abstract: The present invention is at least 8.0 pH is in aqueous solution concentration of 0.5% by weight of the formula R 1 R 2 R 3 R 4 N + X - (In the formula, R 1 is 6 R 2 and R 3 are each independently selected from C 1-4 alkyl or alkenyl, and R 4 is one or more of C 5-11 alkyl or alkenyl. X − is a counter ion that does not substantially exchange with hydroxide ions at 20 ° C. in a 0.5% by weight aqueous solution of the detergent composition). Or a component thereof. |
