Abstract
A fabric softener composition comprising a stable, clear single phase solution of an anionic surfactant having an alkyl radical containing at least eight carbon atoms, a cationic surfactant, water and an effective amount of propylene glycol and an alkali metal salt of benzene, toluene or xylene sulfonate. The fabric softener may be highly concentrated and has the property that when added to a detergent solution it imparts a fabric softening effect but does not lessen the detergency of the solution.
Claims9
A fabric softener composition comprising a stable clear single phase solution of from about 10 to about 16 wt % of an anionic surfactant having an alkyl radical containing at least eight carbon atoms, from about 20 to about 35 wt. % of a cationic surfactant, from about 15 to about 25 wt. % of propylene glycol, from about 8 to about 12 wt. % of an alkali metal salt of benzene sulfonate, toluene sulfonate or xylene sulfonate and a maximum of about 30 wt. % water.
A fabric softener comprising a stable clear liquid solution containing from about 10 to about 16 weight% of an alkyl sulfonate anion having an alkyl radical containing at least eight carbon atoms, from about 20 to about 35 weight% of a quaternary ammonium salt cation having an alkyl radical containing at least eight carbon atoms, from about 15 to about 25 weight % of propylene glycol, from about 8 to about 12 weight % of sodium xylene sulfonate and about 30 weight% maximum of water.
