COMPOSITION BASED ON POLYMER NANOLATEX FOR
LAUNDRY CARE
The present invention relates to a composition for the care of laundry ("textile care") including cotton, comprising a polymer nanolatex not soluble in the conditions of direct and / or indirect use in an aqueous or wet medium of said composition.

 By care of the laundry is meant the protection of the latter with respect to phenomena of physical or chemical degradation and / or the provision thereof of benefits such as softening and / or anti-creasing properties.

 Cleaning the machine laundry leads to physical and chemical degradation of the fibers and especially cotton fibers. The alkalinity delivered by the detergents as well as certain specific compounds such as the oxidizing substances (perborate, percarbonate) or certain enzymes can be at the origin of the chemical degradation of the cotton fibers. But it is usually the conjunction of chemical and mechanical actions that leads to fiber degradation. The mechanical action is produced during washing, rinsing, spinning or drying, when the latter takes place in a dryer. This degradation of the fibers leads to the formation of fibrils on the surface of the textile which finally gives a loss of brightness of the colored textiles. This degradation also induces a decrease in the resistance of the textile which has the extreme can lead to tearing of the tissues. This degradation of textiles can be evaluated quantitatively either by a loss of colors of colored textiles or by a decrease in the breaking energy of the textile. It is generally necessary to carry out 10 to 20 cumulative machine washes to perceive this type of degradation.

Cleaning the washing machine which systematically involves a wringing operation also leads to a crumpled cloth which is accentuated during drying, in particular by the formation of inter-fiber hydrogen bonds. An ironing operation is therefore necessary to obtain a presentable appearance of the laundry.

In order to reduce fiber degradation during washing or rinsing, suppliers of chemicals or detergents have made changes to detergent formulas or the use of certain specific additives.

In particular, detergents which do not comprise an oxidizing system, but which have diminished cleaning capacities, may be mentioned in particular.

A washing operation is carried out in a laboratory apparatus Tergotometer well known in the art of detergent composition formulators. The device simulates the mechanical and thermal effects of American pulsator-type washing machines, but thanks to the presence of 6 washing pots, it allows simultaneous series of tests with a considerable saving of time.

<Desc / Clms Page number 21>

Cut pieces of unpainted cotton of dimensions 25x25 cm are cut.

The cotton test pieces are first ironed in order to have all the same level of creasing before washing.

They are then washed with the aid of the above detergent formulation containing the latex (I) and rinsed once, under the following conditions: - number of test pieces per pot of the Tergotometer: 2 - volume of water: 1 liter - 30 TH French hardness water obtained by appropriate dilution of Contrexéville brand mineral water - laundry concentration: 5 g / l - washing temperature: 40 C - washing time: 20 min - shaking speed of the Tergotomètre: RPM - rinsing with cold water (about 30 TH) - rinsing time: 5 minutes The test specimens are then crumpled under a 3kg press for 20 seconds, then left to dry vertically overnight.

 The same operation is carried out using the same detergent formulation but free of latex (1).

 A color digital photograph of the dry specimens is then made, which is then transformed into 256 gray levels (gray scale from 0 to 255).

We count the number of pixels corresponding to each level of gray.

For each histogram obtained, the standard deviation # of the distribution of the gray level is measured.

 # 1 corresponds to the standard deviation obtained with the detergent formulation containing no latex. a2 corresponds to the standard deviation obtained with the detergent formulation containing the latex (1).

The performance value is given by the equation - ## = a2-al The performance values obtained are as follows:
