CLEANING LIQUID
Document Type and Number:
Japanese Patent JP3486028
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a safe cleaning liquid, comprising a lactic acid ester salt of a long-chain aliphatic carboxylic acid having a specific purity and a sucrose ester of a fatty acid, hardly causing skin irritation, excellent in detergency, stability in hard water, feeling of use and appearance without any unpleasant smell and suitable for foods, skin, hair, etc.
SOLUTION: This cleaning liquid comprises (A) a lactic acid ester salt of a long-chain aliphatic carboxylic acid having ≥80mol% purity [e.g. a lactic acid ester salt, composed of a carboxylic acid having ≥8C atoms in the long chain direction, especially an 8-18C aliphatic carboxylic acid and prepared by reacting (A1) a lactic acid ester of a long-chain aliphatic carboxylic acid with (A2) a basic substance at (1/0.9) to (1/1.3) molar ratio of the components (A1)/(A2)] and (B) a sucrose ester of a fatty acid (e.g. a sucrose ester of an 8-18C aliphatic carboxylic acid) at (90/10) to (1/99) weight ratio of the components (A)/(B) and, as necessary, further (C) 0.01-50wt.% chelating agent.
