Definitions
- the present invention concerns detergent compositions having reduced dye transfer properties
- GB1348212 to Procter and Gamble, discloses detergent composition
- a nonionic detergent and a partially or completely water-soluble polymeric ingredient which is a homo-polymer of vinyl pyrrolidone or a copolymer of vinyl pyrrolidone and a suitable comonomer and a builder salt, the weight ratio of nonionic detergent to polymeric ingredient being from 95:5 to 60:40, The weight ratio of builder salt to total surface-active agent is required to be in the range from 20:1 to 1: 5.
- US 4753750 discloses liquid heavy duty laundry detergent composition
- a suspension of builder salt in liquid nonionic surfactant contains as a viscosity and gel controlling agent an alkylene glycol monoalkyl ether, especially diethyleneglycol monobutyl ether.
- wash systems comprising non-ionic surfactants with dye transfer inhibiting polymers and very low ionic strength, effectively prevent dye transfer for a wide range of dyes.
- the present invention provides a laundry detergent composition comprising:
- the present invention provides a domestic method of washing coloured and white fabrics together comprising the following steps:
- the composition comprises from 10 to 95 wt%, preferably from 35 to 70 wt% of a non-ionic surfactant. Mixtures of non-ionic surfactant may be used.
- the non-ionic surfactant may be selected from alcohol ethoxylates, from C 6 -C 12 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), block alkylene oxide condensate of C 6 to C 12 alkyl phenols, alkylene oxide condensates of C 8 -C 22 alkanols and ethylene oxide/propylene oxide block polymers (PluronicTM-BASF Corp.).
- non-ionic surfactant may be selected.
- Ionic species include charged surfactants, charged organic species, and inorganic ions.
- the ionic strength of a solution of 10g L -1 of the composition in distilled water is less then 0.05, preferably less than 0.007, more preferably less than 0.001.
- the composition should contain less than 1 wt% of charged surfactant, for example Linear alkyl benzene sulphonates salts (LAS), Alkyl sulphate surfactants, alkyl ethoxylated sulphate surfactants, cationic surfactant, soaps and zwiterionic surfactants.
- charged surfactant for example Linear alkyl benzene sulphonates salts (LAS), Alkyl sulphate surfactants, alkyl ethoxylated sulphate surfactants, cationic surfactant, soaps and zwiterionic surfactants.
- the formulation should contain less than 0.1 wt% of charged surfactants, most preferably charged surfactants should be absent. In practice, small amount of charged components will always be present due to contaminants.
- the laundry detergent compositions according to the present invention comprising from 0.01% to 20 %, preferably from 0.5% to 5%, more preferably from 0.2% to 2 % by weight of an anti-dye transfer polymer (ADTP).
- ADTPs are normally incorporated into cleaning compositions in order to inhibit the transfer of dyes from coloured fabrics onto fabrics washed therewith.
- suitable ADTPs are polyamine N-oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinylpyrrolidone polymers, polyvinyloxazolidones and polyvinylimidazoles or mixtures thereof.
- ADTPs anti-dye transfer polymers
- Colorants may be selected from pigments, acid dyes, direct dyes, basic dyes, solvent and disperse dyes. It is preferred that the colorants pigments, solvent and disperse dyes to avoid addition of ionic strength.
- Blue and violet shading dyes that deposit onto fabric are often used at low levels in detergent formulations to enhance the whiteness of fabrics as discussed in WO2006/032327 (Unilever ).
- fluorescer do not deposit effectively so it is preferred that the formulation contains a shading dye to counteract fabric yellowing due to ageing.
- Acid, direct and basic dye shading dyes are not suitable for the current application, as they are water soluble and the formulation will prevent them from depositing.
- shading dyes selected from Blue and violet solvent and disperse dyes and pigments are used. These shading agents deposit via different mechanism to the water soluble dyes and still deposit with the current formulations.
- Preferred dyes are solvent violet 13, disperse violet 27, disperse violet 26, disperse violet 28, disperse violet 77.
- Organic pigments are described in 'Industrial Organic Pigments', Wiley VCH 2004 by W.Herbst and K.Hunger .
- Dyes are organic chemicals that are soluble in their application medium.
- Pigments are inorganic or organic particles that are insoluble in their application medium.
- pigments When pigments are present they are preferably present at levels of 0.0001 to 0.1%, preferably 0.0005 to 0.005 wt%.
- Inorganic pigments such as pigment blue 29 or pigment pigment violet 15 may be used, however organic pigments are preferred.
- Preferred pigments are pigment blue 1, 1:2, 1:3, 2, 2:1, 2:2, 3, 4, 5, 7, 9, 10, 10:1, 11, 12, 13, 14, 15, 15:1, 15:2, 15:3, 15:4, 15:6, 16, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 32, 34, 35, 36, 56, 57, 58, 59, 60, 61, 61:1, 62, 63, 64, 65, 66, 67, 69, 71, 72, 73, 74, 75, 79, 80, 83 and pigment violet 1, 1:1, 1:2, 2, 3, 3:1, 3:3, 3:4, 5, 5:1, 7:1, 8, 9, 11, 12, 13, 14, 15, 16, 18, 19, 23, 25, 27, 28, 29, 31, 32, 35, 37, 39, 41, 42, 43, 44, 45, 47, 48, 50, 54, 55 and 56
- More Preferred organic pigments are pigment violet 1, 1:1, 1:2, 2, 3, 5:1, 13, 23, 25, 27, 31, 37, 39, 42, 44, 50 and Pigment blue 1, 2, 9, 10, 14, 18, 19, 24:1, 25, 56, 60, 61, 62, 66, 75, 79 and 80.

- NI(7EO) refers to an alcohol ethoxylates, R-(OCH 2 CH 2 ) n OH where R is an alkyl chain of 12 to 15 carbon chain length with about 7 ethylene oxide groups per molecule.
- R is an alkyl chain of 12 to 15 carbon chain length with about 7 ethylene oxide groups per molecule.
- NI(30EO) a C12-13 mixture with about 30 moles of ethylene oxide
- NI(3EO) a C12-13 mixture with about 3 moles of ethylene oxide.
- LAS linear alkyl benzene sulphonate.
- SLES (3EO) is a C 12 -C 18 alkyl polyethoxylate (3.0) sulphate.
- PVP is polyvinylpyrolidone.
- the all non-ionic formulation give much lower dye transfer to the cloth, shown by the lower ⁇ E values.
- the all non-ionic formulation without ionic strength (provided by NaCl) shows the least dye transfer.
- the non-ionic surfactant with longer EO chains are more effective at reducing dye transfer.
- the 1g/L NI (7EO) + 0.1g/L PVP effectively prevents nearly all of the dyes from transferring to the white cotton, unlike the other surfactants systems.
