Abstract
A liquid cleansing agent or detergent compositions which separates into at least two aqueous phases contains at least one surfactant in a concentration or less than 10% and at least one electrolyte in the concentration of less than 15%. Optionally, the composition contains less than 10% of organic solvent and less than 6% of sodium hexametaphosphate.
Claims26
Liquid detergent or cleansing composition which separates into two aqueous phases when left to stand, containing at least one surfactant in a concentration of less than 10% by weight, containing at least one electrolyte in a concentration of less than 15% by weight, and containing at least one other compound which promotes phase separation and comprises at least one hydrophobic element and at least one anionic group, provided the composition contains, if any at all, less than 10% by weight of organic solvent and less than 6% by weight of sodium hexametaphosphate.
A method for cleaning a hard surface which comprises applying thereto a liquid detergent or cleansing composition which separates into two aqueous phases when left to stand, containing at least one surfactant in a concentration of less than 10% by weight, containing at least one electrolyte in a concentration of less than 15% by weight, and containing at least one other compound which promotes phase separation and comprises at least one hydrophobic element and at least one anionic group, provided the composition contains, if any at all, less than 10% by weight of organic solvent and less than 6% by weight of sodium hexametaphosphate.
A method for washing soiled fabric which comprises immersing said fabric in an aqueous washing medium which comprises a liquid detergent or cleansing composition which separates into two aqueous phases when left to stand, containing at least one surfactant in a concentration of less than 10% by weight, containing at least one electrolyte in a concentration of less than 15% by weight, and containing at least one other compound which promotes phase separation and comprises at least one hydrophobic element and at least one anionic group, provided the composition contains, if any at all, less than 10% by weight of organic solvent and less than 6% by weight of sodium hexametaphosphate.
A liquid cleansing and detergent composition containing at least one surfactant, an electrolyte which promotes the separation of said composition into at least two aqueous phases, and containing at least one other compound which promotes phase separation and comprises at least one hydrophobic element and at least one anionic group.
A liquid cleansing and detergent composition which comprises at least one surfactant, at least one limestone-removing acid and xylol and/or cumol sulphonic acid or salts thereof to promote separation of said composition into at least two aqueous phases.
