Abstract
The present invention provides an aqueous bleaching composition comprising from about 1.0% to 10.0% by weight of alkali metal hypochlorite, from about 0.05% to 5.0% by weight of alkali metal hydroxide to provide the composition with a pH in the range of from about 9 to 14; from about 0.02% to 5.0% by weight of a metal silicate or mixtures of metal silicates; from about 0.0001% to 0.2% by weight of a metal periodate; and water. The compositions reliably protect the fabric against yellowing and weakening while providing protection to stainless steel metal parts of the washing machine and metal garment decors such as buckles, buttons, etc.
Claims20
A method of reducing damage to metal parts of a washing machine during a laundry cycle using a hypochlorite-containing bleach, the method comprising the step of
- adding to said laundry cycle an aqueous liquid bleaching composition consisting essentially of:
- i. from about 1.0% to 10.0% by weight of alkali metal hypochlorite,
- ii. from about 0.05% to 5.0% by weight of alkali metal hydroxide to provide the composition with a pH in the range of from about 9 to 14;
- iii. from about 0.02% to 5.0% by weight of an alkali metal silicate or mixtures of alkali metal silicates;
- iv. from about 0.0001% to 0.1% by weight of an alkali metal periodate;
- v. water, and
- vi. optionally a fragrance wherein the fragrance either is added directly to the composition or is added as an emulsified solution wherein the emulsified solution optionally contains a surfactant that is compatible with hypochlorite,
- wherein the presence of said bleaching composition during said laundry cycle does not cause damage to metal parts of the washing machine with which it comes into contact.
A method of bleaching one or more fabrics having one or more metal accessories attached thereto while protecting said metal accessories from bleach damage, the method comprising the step of
- contacting the fabrics and the metal accessories attached thereto with an aqueous liquid bleaching composition consisting essentially of:
- i. from about 1.0% to 10.0% by weight of alkali metal hypochlorite,
- ii. from about 0.05% to 5.0% by weight of alkali metal hydroxide to provide the composition with a pH in the range of from about 9 to 14;
- iii. from about 0.02% to 5.0% by weight of an alkali a metal silicate or mixtures of alkali metal silicates;
- iv. from about 0.0001% to 0.1% by weight of an alkali a metal periodate;
- v. water, and
- vi. optionally a fragrance wherein the fragrance either is added directly to the composition or is added as an emulsified solution wherein the emulsified solution optionally contains a surfactant that is compatible with hypochlorite,
- wherein said bleaching composition does not cause damage to said metal accessories with which it comes into contact.
