Abstract
Improved color protection of detergents and cleansers used for washing or cleaning colored textile fabrics is provided with use of porous polyamide particles in the detergent or cleanser.
Claims11
Washing, laundry pre-treatment, laundry post-treatment or cleaning agent comprising a dye transfer inhibitor in the form of porous polyamide particles having
- a number-average particle diameter of 1 to 30 μm,
- a BET specific surface area (to DIN 66131) of 5 m2/g or more,
- an oil absorption capacity (boiled linseed oil) of 160 ml/100 g or more,
- a crystallinity (DSC measurement) of 40% or above, and
- a quotient of volume-average particle diameter to number-average particle diameter of 1.0 to 1.5.
Method of preventing the transfer of textile dyes from dyed textiles onto undyed or differently colored textiles when they are jointly washed comprising washing dyed textiles together with undyed and/or differently colored textiles in surfactant-containing aqueous solutions comprising porous polyamide particles having
- a number-average particle diameter of 1 to 30 μm,
- a BET specific surface area (to DIN 66131) of 5 m2/g or more,
- an oil absorption capacity (boiled linseed oil) of 160 ml/100 g or more,
- a crystallinity (DSC measurement) of 40% or above, and
- a quotient of volume-average particle diameter to number-average particle diameter of 1.0 to 1.5.
