Embodiment Construction

[0043] The composition of the present invention is typically used as part of a fabric care composition delivered to the rinse cycle of an automatic washing machine.

[0044] Nanoparticles

[0045] The composition of the present invention comprises a dispersion of nanoparticles that acts as a friction component when deposited on a fabric. The particles can be inorganic or organic nanoparticles or a mixture of one or more nanoparticles.

[0046] Suitable inorganic nanoparticles include silicon dioxide (SiO 2 ), titanium dioxide (TiO 2 ), alumina (Al 2 O 3 ), zinc oxide (ZnO) and mixed oxides such as ITO (indium tin oxide, In 2 O 3 -SnO 2 ).

[0047] The readily available and preferred inorganic nanoparticles are amorphous silica obtained in the form of sol or colloid, as defined in The Chemistry of Silica, RK Iler, Wiley-Interscience, New York, 1979, page 330.

[0048] The silica nanoparticles can also be a non-silicon core, as long as the surface of the nanoparticles is coated with...

Abstract

A fabric treatment composition for use in the rinse cycle of a washing machine for reducing in-wear wrinkle in fabrics, the composition comprising: a) a nanoparticle dispersion comprising particles having an average particle size in the range 5 to 500 nm, b) a lubricant phase selected from a cationic fabric softener, a silicone oil, sucrose polyester oil and mixtures thereof, and c) water in which the weight ratio of a) : b) is in the range 3 : 1 to 1 : 3.

Description

Invention field [0001] The present invention relates to fabric care compositions. More specifically, the present invention relates to a rinse cycle fabric care composition that reduces fabric wrinkling, especially drying or wearing wrinkles to give the fabric an ironed appearance throughout the day. Background of the invention [0002] Fabric care compositions that reduce wrinkles in worn fabrics are known. [0003] Mechanical wrinkle reduction techniques, such as heating and pressing (for example, ironing), are effective methods for smoothing clothes. However, due to a certain range of shear, torsion and compression deformation forces applied during wearing, the effect cannot be sustained, and wrinkles reappear. Body temperature and humidity have an effect on the fabric to relax it, and therefore aggravate the wrinkling of these deformation forces. [0004] The existing anti-wrinkle technology can be explained into three methods: [0005] (a) Use lubricant to improve recovery fr...
