Definitions

  • the bleaching compositions are formulated as solids, for example as granules, tablets or powders, they are preferably applied on the fabrics to be bleached according to the present invention in a liquid form, i.e., solid compositions are used in combination with an appropriate solvent, typically water.
  • hypohalite bleaches among those described above are the alkali metal or alkaline earth metal hypochlorites selected from the group consisting of sodium, potassium, magnesium, lithium and calcium hypochlorites, and mixtures thereof.
  • Sodium hypochlorite is the most preferred hypohalite bleach.
  • Exemplary surfactants are C 12 -C 18 alkyl polyethoxylate (1.0) sulphonate, C 12 -C 18 E(1.0)M), C 12 -C 18 alkyl polyethoxylate (2.25) sulphonate, C 12 -C 18 E(2.25)M), C 12 -C 18 alkyl polyethoxylate (3.0) sulphonate C 12 -C 18 E(3.0), and C 12 -C 18 alkyl polyethoxylate (4.0) sulphonate C 12 -C 18 E(4.0)M), wherein M is conveniently selected from sodium and potassium.
  • betaine/sulphobetaine Some common examples of betaine/sulphobetaine are described in U.S. Pat. Nos. 2,082,275, 2,702,279 and 2,255,082, incorporated herein by reference.
  • alkalinity sources include ammonia, ammonium carbonate and hydrogen carbonate.
  • the bleaching compositions of the present invention may further comprise another surfactant in addition to the surfactants which are part of the fabric protective system.
  • Said surfactant may be present in the bleaching compositions according to the present invention in amounts up to 30%, preferably of from 0.1 % to 20% and more preferably of from 0.1 % to 10% by weight of the total composition.
  • optical brighteners which are useful in the present bleaching compositions are those identified in U.S. Patent 4,790,856. These brighteners include the PHORWHITE® series of brighteners from Verona. Other brighteners disclosed in this reference include: Tinopal-UNPA®, Tinopal CBS® and Tinopal 5BM® available from Ciba-Geigy; Artic White CC® and Artic White CWD®; the 2-(4-styryl-phenyl)-2H-naptho[1,2-d]triazoles; 4,4'-bis(1,2,3-triazol-2-yl)-stilbenes; 4,4'-bis(styryl)bisphenyls; and the aminocoumarins.
  • the bleaching compositions according to the present invention may comprise up to 1.0% by weight of the total composition of a brightener or a mixture thereof, preferably from 0.005% to 0.5%, more preferably from 0.005% to 0.3% and most preferably from 0.008% to 0.1%.
  • the process of bleaching fabrics comprises the step of contacting fabrics with a liquid bleaching composition according to the present invention, in its neat form, of allowing said fabrics to remain in contact with said bleaching composition for a period of time sufficient to bleach said fabrics, typically 5 seconds to 30 minutes, preferably 1 minute to 10 minutes and then rinsing said fabrics with water. If said fabrics are to be washed, i.e., with a conventional composition comprising at least one surface active agent, said washing may be conducted before or after that said fabrics have been bleached.
