Definitions

• the present invention is in the field of fabric treatment.
• it relates to a method of treating fabrics in a dyer comprising the step of delivering a composition onto the fabrics, the composition comprising a solvent and low stickiness active ingredients.
• the present invention is directed to a method of treating fabrics in a dryer.
• the method is suitable for the treatment of wet and dry fabrics.
• the method comprises the steps of placing fabrics into the dryer, applying a liquid composition onto the load and drying the fabrics.
• the composition can be delivered onto the load before, during and/or after the drying of the fabrics.
• the composition comprises a solvent and active ingredients. The composition does not become sticky during use, this avoids lint build up and optimizes the amount of active ingredients that goes onto the fabrics.
• the stickiness of the active ingredients is measured by evaporating the solvent of the composition to leave concentrated samples.
• the concentrated samples are rehydrated and the stickiness of O.lg of the sample is measured in a texture analyser as explained in more details herein below.
• Suitable active ingredients for use in the composition of the method of the invention include any ingredient capable of conferring a benefit to fabrics, it also includes any ingredient that contribute to the stability of the composition, such as for example preservatives and ingredients that make the composition fabric substantive.
• Preferred active ingredients for use in the composition of the method of the invention include perfume, surfactant and preservative.
• composition is free of any ingredient that becomes sticky under the conditions specified herein below.
• composition is free from cyclodextrins (material widely used in fabric treatment perfume compositions).
• the compositions for use in the method of the invention are aqueous compositions.
• Water is the main liquid carrier of the active ingredients due to its low cost, availability, safety, and environmental compatibility.
• water can be distilled, deionized, or tap water.
• Water not only serves as a liquid carrier for the active ingredients, but it can also provide some odor controlling effect of its own. It has been discovered that the intensity of odor generated by some polar, low molecular weight organic amines, acids, and mercaptans is reduced when the odor-contaminated fabrics are treated with an aqueous solution. Water is also very useful for fabric wrinkle removal or reduction. Without wishing to be bound by theory, it is believed that water breaks many intra-fiber and inter-fiber hydrogen bonds that keep the fabric in a wrinkle state. It also swells, lubricates and relaxes the fibers to help the wrinkle removal process.
• the solvent in addition to water, can contain a low molecular weight organic solvent that is highly soluble in water, e.g., ethanol, propanol, isopropanol, and the like, and mixtures thereof.
• Low molecular weight alcohols can help the treated fabric articles to dry faster and also provide some antimicrobial benefit.
• the optional water soluble low molecular weight solvent can be used at a level of up to about 50%, typically from about 0.1% to about 20%, preferably from about 0.2% to about 15%, more preferably from about 0.5% to about 10%, by weight of the total solvent.
• Factors that need to be considered when a high level of solvent is used in the composition are odor, flammability, and environment impact.
• the actives ingredients of the composition have a maximum stickiness (as measured under the conditions described herein) of about 2500 Force (g), preferably about 2000, more preferably about 1600 and especially about 1400 Force (g).
• each single active ingredient has a maximum stickiness of about 2800 Force (g), more preferably about 2500, even more preferably about 2000 and especially below 1800 Force (g). Stickiness measurement of the active ingredients
• Stickiness is measured by using a texture analyser.
• a 100 ml sample of a composition is placed in an open container (circular glass beaker - radius 4cm, depth 8cm) in an oven at 90 C for 24hours. This removes most of the solvent from the composition and leaves a concentrated sample of the active ingredients. This process of evaporation of the solvent from the sample is similar to that which would occur in a tumble drier during drying. The concentrated sample is then removed from the oven and allowed to cool to room temperature. The sample remains as an oily liquid when the solvent is evaporated and after the solvent is evaporated. Samples which go through a sticky phase as they solidify are outside the scope of the invention.
• the sample is re-hydrated with 2 ml of distilled water and stirred with a small spatula until a uniform concentrated solution is formed.
• the sample is left to rest for an hour.
• a 0.1 g of this sample is weighed into a well of a polycarbonate slide.
• the well is circular and has a depth of 4mm.
• the well is 2.5mm wider than probe and in such a position that the probe is centre to the well when the plate is clamped into place allowing equal gap around all sides.
• the stickiness measurement is then conducted on the sample using a Texture Analyser.
