Benefits of technology

[0043]Surprisingly, it has been found that certain nano-particulate friction enhancers when combined with certain lubricants at certain particle to lubricant ratios work in synergy to noticeably reduce the tendency of fabrics to wrinkle in wear. The balance of the nanoparticles and lubricant phase provides the desired properties by virtue of their physical properties. The compositions of the invention are free from catalysts and curing agents and do not react to form a film when deposited on the fabric. Preferred nanoparticle phases include colloidal silica and silicone resins, preferred lubricants are silicone oils and sucrose polyester oils. Preferred ratios of particle phase to lubricant phase range from 3:1 to 1:3 more preferably 2:1 to 1:2.
[0089]The composition can conveniently be delivered from a spray during the domestic ironing operation. Compositions other than those containing silicone resin nanoparticles may be delivered via a spray through a steam iron or steam generator iron.

Problems solved by technology

However the effect is not permanent and wrinkles reappear due to a range of shear, torsion and compressive deformation forces applied in wear.
There has been no product available on the market that meets consumers need for an effective in-wear wrinkle or all-day-ironed look benefit.

Abstract

An ironing aid fabric treatment composition comprising: a) a nanoparticle dispersion comprising particles having an average particle size in the range 5 to 500 nm, b) a lubricant phase comprising a lubricant selected from silicone oil, sucrose polyester oil and mixtures thereof, and c) water wherein the weight ratio of a):b) is in the range 4:1 to 1:4, with the proviso that when the colloidal nanoparticle dispersion comprises a silicone resin the composition is not delivered through an iron.

Description

FIELD OF THE INVENTION[0001]The present invention relates to fabric care compositions. More specifically, the invention relates to fabric care compositions for ironing which reduce the wrinkling of fabrics in particular the dry or in-wear wrinkling giving fabrics an all-day-ironed look.BACKGROUND OF THE INVENTION[0002]Fabric care compositions which reduce the wrinkling of fabrics being worn are known.[0003]Mechanical wrinkle reduction techniques, such as heat and pressure, for example in ironing, are effective ways of flattening garments. However the effect is not permanent and wrinkles reappear due to a range of shear, torsion and compressive deformation forces applied in wear. The body's heat and humidity work on the fabric to relax it and hence to enhance the wrinkling of these deformational forces.[0004]The prior art anti-wrinkle teaching can be rationalised into three approaches;[0005](a) using lubricants to improve recovery from crease,[0006](b) using cross-linkers and film fo...
