DESCRIPTION

Ingredient for use in a composition for washing clothes Field of the invention

The present invention relates to an ingredient for use in a laundry composition. More particularly, the invention relates to the use of a silicone functionalized with betama as a fabric softening material.

Background of the invention

Textile fabrics, which includes clothing, have traditionally been cleaned with laundry detergents. It is common that after cleaning the tissues acquire a rough nature to the touch. To avoid the disadvantages of this roughness in the clothes after cleaning and, especially, the one that is felt after several cycles of washing and use, technologies have been developed to increase the softness of the tissues, which includes conditioning compositions that are they add to the rinse and softener systems that are added to the detergent composition. These formulations are sometimes classified as softeners in laundry detergents.

A liquid detergent composition for washing clothes with silicone agents for tissue care is known from WO 2005/105969.

There is a need to improve softening in laundry detergents.

It has been found that it is possible to use a functionalized silicone with betama as an effective material to soften tissues.

Summary of the invention

The invention relates to the use of a silicone functionalized with betama at a level of 0.1 to 10% by weight, as a fabric softening material in a laundry detergent composition comprising:

(a) from 1 to 40% by weight of non-ionic surfactant and

(b) from 1 to 40% by weight of anionic surfactant.

When used, preferably betama functionalized silicone is present at a level of 0.25 to 10% by weight, more preferably, at a level of 0.25 to 7.5% by weight, more preferably, at a level of 0.5 to 5% by weight.

When used, preferably the non-ionic surfactant and the anionic surfactant, each of them, is present at a level of 1 to 40% by weight, more preferably 4 to 40% by weight, more preferably still 4 to 20% in weigh.

Preferably, the nonionic surfactant comprises an alcohol ethoxylate.

Preferably in the composition for washing clothes in which a silicone functionalized with betama is used, it is present or cationic polymer at a level of 0.1 to 2.5% by weight.

Preferably, the laundry composition is a liquid detergent composition for laundry.

If the composition is a liquid, then it is preferred that it has a pH of 6.2 to 9, more preferably, a pH of 6.5 to 8.5.

Detailed description of the invention

As used herein, the term "comprising" means that it includes, that it is constituted by, that it is comprised of, consisting of and / or consisting essentially of.

All the percentages mentioned are percentages by weight based on the total amount present in the composition for the laundry, unless otherwise indicated.

Form of the invention

The invention relates to the use of betama functionalized silicone to impart softness to tissues. In particular, betama functionalized silicone is supplied to the tissues at a level of 0.1 to 10% by weight as a fabric softening material in a composition for washing clothes comprising: (a) from 1 to 40% by weight of non-ionic surfactant and (b) from 1 to 40% by weight of anionic surfactant.

Smoothness was measured using a texture analyzer (TA, Texture Analyzer) Stable Micro Systems XT plus, with the optional friction module connected. The TA is a commercial instrument that incorporates an actuator mechanism and a 5 kg load cell. The treated tissue was spread on the horizontal test platform of the instrument and a cylindrical probe of neoprene rubber was placed, which was connected to the load cell on the surface of the tissue. The texture analyzer is programmed to move the probe over the tissue, forward and backward, over a distance of 40 mm, at a speed of 10 mm / s. As the probe moves, the software records the frictional force experienced by the probe. The average coefficient of friction throughout the test is used as a measure of smoothness.
