Cold cleaning compositions of the microemulsions type

Cleaning composition which is provided in the form of a microemulsion which is stable at room temperature, the said composition comprising:

• (A) water;
• (B) at least one organic solvent which is liquid at room temperature;
• and
• (C) at least one surface-active agent, characterized in that:
• (A) represents from 30 to 70 parts by weight;
• (B) represents from 20 to 60 parts by weight;
• and
• (C) represents from 5 to 30 parts by weight,
• (A)+(B)+(C) representing 100 parts by weight;
• and
• the organic solvent or solvents (B) being chosen from:
• (1) aliphatic alcohols;
• (2) aliphatic esters;
• (3) aliphatic diesters;
• (4) aliphatic hydrocarbons;
• (5) halogenated aliphatic hydrocarbons;
• (6) aromatic hydrocarbons;
• (7) aliphatic ketones;
• (8) aliphatic ethers;
• (9) alkylene glycol, dialkylene glycol and trialkylene glycol monoethers;
• (10) (di)alkylene glycol diethers;
• and
• (11) (di)alkylene glycol ether acetates;
• and
• the surface-active agent or agents (C) being chosen from those of the formula (I):
• 4
• in which:
• R1 and R2 each independently represent a linear or branched C5-C20 alkyl radical;
• M is a cation chosen from Na+, K+ and NR4+, the R groups each independently representing hydrogen or a C1-C4 alkyl radical.
