Description

TECHNICAL TERRITORY

The The present invention relates to bleaching compositions. The Compositions of the present invention are in particular for Bleaching laundry suitable.

BACKGROUND

compositions for bleaching laundry are already detailed in the art been described. Bleaching compositions can be used in Peroxide bleaching compositions and hypochlorite bleaching compositions be divided. Have peroxide bleach compositions across from Hypochlorite bleach compositions have the advantage that They are usually considered somewhat safer for the textiles especially for colored textiles. However, peroxide compositions have the inconvenience on that they often are chemically unstable, making it difficult to use peroxide bleach compositions to formulate that over sufficiently long enough to be marketable. A possible solution This problem exists in the formulation of compositions with a high peroxide content to extend the "effective" period of the composition there is a possible Disadvantage of this solution in that compositions that are still high in peroxide can reach the consumer, causing skin irritation (eg, itching) on contact with the peroxide composition. This irritation, especially the appearance of itching, is little pronounced and completely reversible, but represents the user a possible inconvenience represents.

Further For example, peroxide species are generally poor at low temperatures Bleaching agents such that activated peroxide bleach compositions have to be formulated when she over a larger temperature range should be used. Activated bleaching compositions include a bleach activator, typically a peracid precursor, which in an aqueous Medium reacts with hydrogen peroxide to form the corresponding peracid. This peracid is an effective bleaching agent at low temperatures.

Consequently It is an object of the present invention to provide a peroxide bleach composition formulate that is stable without resorting to higher peroxide levels to have to, and which can be activated in a stable manner.

It It is also an object of the present invention to provide bleach compositions to formulate with excellent bleaching performance.

When Result, we have now found that this goal through the formulation an aqueous Emulsion can be achieved as described herein.

Bleaching compositions formulated as emulsions have been described in U.S. Pat EP 598 170 and co-pending patent application no. EP-A-687 726. The compositions described in '170 are emulsions comprising hydrogen peroxide in one phase and a hydrophobic liquid component in the other phase. This hydrophobic liquid component may be a peracid precursor. The compositions described in '726 comprise at least two nonionic surfactants and benzoyl peroxide.

WHERE 98/11189 discloses compositions useful as microemulsions or Emulsions containing an aliphatic diacyl peroxide, at least one nonionic surfactant and at least one anionic Include surfactant.
