Abstract
Liquid pretreater compositions packaged in a spray-type dispenser are described, said compositions comprising a peroxygen bleach, a surfactant and a bleach activator. A process of cleaning fabrics with a liquid composition comprising a peroxygen bleach and a surfactant, said process comprising the steps of dispensing said composition from a spray-type dispenser onto a least a portion of said fabrics, allowing said composition to remain in contact with said fabrics and then washing said fabrics, is said to reduce the loss of tensile strength and/or the color damage in said fabrics.
Claims13
A process of cleaning fabrics with a liquid composition comprising a peroxygen bleach and a surfactant, said process comprising the steps of dispensing said composition from a spray-type dispenser onto at least a portion of said fabrics, allowing said composition to remain in contact with said fabrics and then washing said fabrics.
A liquid composition packaged in a spray-type dispenser for pretreating fabrics, said composition comprising a peroxygen bleach, a surfactant and a bleach activator.
A process or composition according to any of the preceding claims wherein said peroxygen bleach is hydrogen peroxide, or a water source thereof, or mixtures thereof, and is present in an amount of from 0.5% to 20% by weight of the total composition and preferably of from 2% to 15%.
A process or composition according to any of the preceding claims wherein said surfactant, or mixtures thereof, is present in an amount up to 40% by weight of the total composition, preferably of from 0.05% to 30% and more preferably of from 1% to 20%.
A process or composition according to any of the preceding claims, wherein said composition further comprises from 1% to 10% by weight of the total composition, preferably from 2% to 4% of an alcohol according to the formula HO—CR′R″—OH, wherein R′ and R″ are independently H or a C2-C10 hydrocarbon chain and/or cycle, or mixtures thereof, and/or up to 20% by weight of the total composition, preferably from 0.1% to 10%, more preferably from 0.5% to 5% of an alcohol having the following formula or mixtures thereof:
- 2
- wherein n is an integer between 0 and 10, wherein R, R′, R″, R′″ and Riv may be H or C1-C10 linear or branched alkyl chains, or C1-C10 linear or branched alkenyl or alkinyl chains.
A process or composition according to any of the preceding claims wherein said spray-type dispenser is a trigger spray.
The use of a liquid composition packaged in a spray-type dispenser, said composition comprising a peroxygen bleach and a surfactant, for pretreating a colored soiled fabric before said colored soiled fabric is washed, for reducing color damage of said fabric.
The use of a liquid composition packaged in a spray-type dispenser, said composition comprising a peroxygen bleach and a surfactant, for pretreating a soiled fabric before said soiled fabric is washed, for reducing the loss of tensile strength in said fabric.
