  • Other particularly useful silicone compounds are the self-emulsifying silicone compounds, described in German Patent Application DTOS 2 646 126 published April 28, 1977.
  • An example of such a compound is DC-544®, commercially available from Dow Corning, which is a siloxane-glycol copolymer.
  • compositions can comprise a silicone/silica mixture in combination with fumed nonporous silica such as Aerosil®.
  • compositions of the present invention may comprise a radical scavenger or a mixture thereof.
  • Suitable radical scavengers for use herein include the well-known substituted mono and dihydroxy benzenes and their analogs, alkyl and aryl carboxylates and mixtures thereof.
  • radical scavengers for use herein include di-tert-butyl hydroxy toluene (BHT), hydroquinone, di-tert-butyl hydroquinone, mono-tert-butyl hydroquinone, tert-butyl-hydroxy anysole, benzoic acid, toluic acid, catechol, t-butyl catechol, benzylamine, 1,1,3-tris(2-methyl-4-hydroxy-5-t-butylphenyl) butane, n-propyl-gallate or mixtures thereof and highly preferred is di-tert-butyl hydroxy toluene.
  • Such radical scavengers like N-propyl-gallate may be commercially available from Nipa Laboratories under the trade name Nipanox S1®.
  • Radical scavengers when used are typically present herein in amounts ranging from up to 10% and preferably from 0.001% to 0.5% by weight of the total composition.
  • radical scavengers may contribute to reduce tensile strength loss of fabrics and/or color damage when the compositions of the present invention are used in laundry through the wash application.
  • compositions according to the present invention may further comprise an antioxidant or mixtures thereof.
  • compositions herein may comprise up to 10%, preferably from 0.002% to 5%, more preferably from 0.005% to 2%, and most preferably from 0.01% to 1% by weight of the total composition of an antioxidant.
  • Suitable antioxidants to be used herein include organic acids like citric acid, ascorbic acid, tartaric acid, adipic acid and sorbic acid, or amines like lecithin, or aminoacids like glutamine, methionine and cysteine, or esters like ascorbil palmitate, ascorbil stearate and triethylcitrate, or mixtures thereof.
  • Preferred antioxidants for use herein are citric acid, ascorbic acid, ascorbil palmitate, lecithin or mixtures thereof.
  • the compositions of the present invention may comprise a bleach activator or mixtures thereof.
  • bleach activator it is meant herein a compound which reacts with hydrogen peroxide to form a peracid.
  • the peracid thus formed constitutes the activated bleach.
  • Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides, or anhydrides. Examples of suitable compounds of this type are disclosed in British Patent GB 1 586 769 and GB 2 143 231 and a method for their formation into a prilled, form is described in European Published Patent Application EP-A-62 523.
  • Suitable examples of such compounds to be used herein are tetracetyl ethylene diamine (TAED), sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid as described for instance in US 4 818 425 and nonylamide of peroxyadipic acid as described for instance in US 4 259 201 and n-nonanoyloxybenzenesulphonate (NOBS).
  • TAED tetracetyl ethylene diamine
  • NOBS n-nonanoyloxybenzenesulphonate
  • N-acyl caprolactams selected from the group consisting of substituted or unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam pentanoyl caprolactam or mixtures thereof.
  • a particular family of bleach activators of interest was disclosed in EP 624 154, and particularly preferred in that family is acetyl triethyl citrate (ATC).
  • Acetyl triethyl citrate has the advantage that it is environmental-friendly as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally, it provides good building capacity to the composition.
  • compositions according to the present invention may comprise from 0.01 % to 20%, preferably from 1% to 10%, and more preferably from 3% to 7% by weight of the total composition of said bleach activator.
