A laundry detergent composition comprising:
- from about 1% to about 20% by weight of alkyl ether sulfate of the formula R1—(OCH2CH2)x—O—SO3M, wherein R1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C8 to about C20, and wherein x is from about 0.5 to about 8, and where M is an alkali metal or ammonium cation;
- from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R2—(OCH2CH2)y—OH, wherein R2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C10 to about C18, and wherein y is from about 0.5 to about 15;
- from about 0.1% to about 5% by weight of amine oxide;
- from about 0.1% to about 5% of a cleaning polymer, from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol;
- and water, wherein the composition is substantially free of dye and brightener.
A transparent or translucent liquid laundry detergent composition in a transparent bottle, wherein the composition comprises from about 1% to about 20% by weight of alkyl ether sulfate of the formula R1-(OCH2CH2)x—O—SO3M, wherein R1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C8 to about C20, and wherein x is from about 0.5 to about 8, and wherein M is an alkali metal or ammonium cation;
- from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R2—(OCH2CH2)y—OH, wherein R2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C10 to about C18, and wherein y is from about 0.5 to about 15;
- from about 0.1% to about 5% by weight of amine oxide;
- from about 0.1% to about 5% of a cleaning polymer;
- from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol;
- and water;
- where the transparent or translucent composition has about 50% transmittance or greater of light using 1 cm cuvette at wavelength of 410-800 nanometers;
- and where the transparent bottle has light transmittance of greater than 25% at wavelength of about 410-800 nm.
A method of laundering colored fabric which comprises the steps of:
- providing a detergent composition where the composition comprises from about 1% to about 20% by weight of alkyl ether sulfate of the formula R1-(OCH2CH2)—O—SO3M, wherein R1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C8 to about C20, and wherein x is from about 0.5 to about 8, and wherein M is an alkali metal or ammonium cation;
- from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R2—(OCH2CH2)y—OH, wherein R2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C10 to about C18, and wherein y is from about 0.5 to about 15;
- from about 0.1% to about 5% by weight of amine oxide;
- from about 0.1% to about 5% of a cleaning polymer, from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol;
- and water, where the composition is substantially free of brightener and monoethanolamine;
- diluting a dose of the detergent composition in water by a factor of greater than 500 to obtain a wash liquor which comprises 0.8 to 0.035 g/L of surfactant;
- washing the colored fabric with the wash liquor so formed, where the chlorine scavenging efficiency is at least about 90% at an initial free chlorine concentration of 2.4 ppm.
