Description
- This invention relates to a laundry composition. More particularly, the invention is directed to a softening in the wash laundry composition.
- Textile fabrics, including clothes, have traditionally been cleaned with laundry detergents. After cleaning, fabrics can often feel harsh. To prevent this, especially harshness experienced after multiple wash cycles, technologies have been developed to increase the softness of fabrics, including rinse-added conditioner compositions and softening systems added to the detergent composition.
- Fabric softening silicones have been used to provide softness to fabrics from a laundry detergent composition. However, there is a problem with formulation stability in terms of unacceptable haze.

The addition of the hydrotrope thus aids the clarity/transparency of the composition. Suitable hydrotropes include but are not limited to propylene glycol, ethanol, glycerol, urea, salts of benzene sulphonate, toluene sulphonate, xylene sulphonate or cumene sulphonate. Suitable salts include but are not limited to sodium, potassium, ammonium, monoethanolamine, triethanolamine. Salts of sulphonates can also be considered as anionic surfactants as defined herein. Preferably, the hydrotrope is selected from the group consisting of propylene glycol, xylene sulfonate, ethanol, and urea to provide optimum performance. The amount of the hydrotrope is generally in the range of from 0 to 30%, preferably from 0.5 to 30%, more preferably from 0.5 to 30%, most preferably from 1 to 15%.
- Enzymes can also be present in the formulation. Preferred enzymes include protease, lipase, pectate lyase, amylase, cutinase, cellulase, mannanase. If present the enzymes may be stabilized with a known enzyme stabilizer for example boric acid.
- Water and hydrotropes are mixed together at ambient temperature (approximately 22°C) for 2-3 minutes at a shear rate of 150 rpm using a Janke & Kunkel IKA RW20 overhead mixer. Salts and alkalis are added and mixed for 5 minutes prior to addition of surfactants and fatty acid. The mixture will exhibit a slight exotherm at this point. After allowing to cool to <30°C, the cationic polymer (LR400 added as an aqueous solution) solution, and any remaining components such as perfume, preservatives, dyes and silicones are added. The silicone was added at 1 wt.%, and was added as an emulsion. Formulations with a number are according to the invention, formulations with a letter are comparative.
