Description

DETERGENT COMPOSITIONS CONTAINING AN AMINE SILICONE AND A GLUCAMIDE

The present invention relates to the use, in detergent compositions for laundry, as a color protection agent for white or colored laundry, of an amino silicone in combination with a glucamide surfactant; it also relates to detergent compositions for the laundry comprising said amino silicone associated with a glucamide surfactant, as well as a process for protecting the colors of textile fiber articles by washing said articles using an aqueous medium containing the said detergent compositions.

The use of glucamide surfactants in the deriving formulas is known and described in US-A- 2,965,576 and GB-A- 809,060. These surfactants are known for their effectiveness on oily stains and for their foaming character. The use of amino silicones in detergent formulas is also known because these polymers are capable of being adsorbed on fabrics and give the linen greater softness, a reduction in their crumplability, better retention of perfumes.

The degradation of fabrics, in particular in cotton and in particular colored cottons, is linked to the conjunction of several phenomena, of chemical and physical origins.

Among the chemical phenomena, the desorption of dyes and more particularly of direct dyes is a predominant factor in staining colors. This phenomenon is generally predominant during the first ten washing cycles. Among the physical phenomena, mention may be made in particular of the stirring of the laundry during the washing operation, stirring which leads to deterioration of the cotton fibers by abrasion due to the fiber / fiber or fiber / insoluble compound contacts present in the washing medium. This degradation of the cotton leads to a bleaching of the colored linen, or even pilling, after a greater number of washing cycles.

It has been found that the combination of an amino silicone and a glucamide surfactant in a detergent composition for the laundry, provides better protection of colored cotton articles in the short and long term by acting on both physical and chemical phenomena.

Indeed, it has been found that the amino silicone limits the desorption of the dye in the short term and that the glucamide surfactant limits, by its foaming character, the physical degradations in the long term.
