A method of laundering fabrics includes: a) contacting a laundry detergent to water to form a wash liquor, wherein the laundry detergent includes detersive surfactant, wherein the wash liquor includes detersive surfactant at a concentration in the range of from 100 ppm to 2500 ppm; b) contacting fabric to the wash liquor, and washing the fabric in the wash liquor; c) after a period of time of at least 6 minutes from contacting the fabric to the wash liquor, introducing calcium cations into the wash liquor to form a calcium enriched wash liquor, wherein the calcium enriched wash liquor includes calcium cations at a concentration in the range of from 20 ppm to 400 ppm; d) washing the fabric in the calcium-enriched wash liquor for a period of time of at least 2 minutes; and e) removing the excess calcium-enriched wash liquor from the fabric, and rinsing the fabric in water.

Method of laundering fabric

A process for making a particulate laundry detergent composition, the process includes the steps: (a) contacting water, starch, acid and perfume to form a concentrated aqueous acidic mixture, the concentrated acidic mixture includes: (i) from about 20 wt % to about 60 wt % starch; (ii) from about 10 wt % to about 50 wt % acid; (ii) from about 2 wt % to about 20 wt % perfume; (iv) from 10 wt % to less than about 45 wt % water; the concentrated acidic mixture has a pH of less than about 4.5; (b) subjecting the concentrated acidic mixture to a perfume emulsification step to emulsify the perfume to form an emulsified perfume mixture in fluid form; and (c) spraying the emulsified perfume mixture in fluid form onto base detergent particles so that the emulsified perfume mixture at least partially coats the base detergent particles to form the particulate laundry detergent composition, the base detergent particles include from about 4 wt % to about 60 wt % detersive surfactant.

Process for making a particulate laundry detergent composition

The present invention relates to a process for preparing a solid free-flowing particulate laundry detergent composition, wherein the process includes the steps of: (a) forming a mixture by contacting: (i) molten fatty acid; (ii) liquid alkaline ingredient, and (iii) non-ionic surfactant, to obtain a mixture, wherein the mixture includes: (i) partially neutralized fatty acid component; (ii) non-ionic surfactant; and (iii) water, wherein the molar ratio of fatty acid to liquid alkaline ingredient contacted together in step (a) is above 1:1; (b) contacting the mixture obtained in step (a) to a detergent powder to form a solid free-flowing particulate laundry detergent composition, wherein in step (b) the mixture is contacted to the detergent powder by spraying the mixture at a temperature of greater than 50° C. onto the detergent powder, wherein the detergent powder includes a detergent ingredient.

Process for making a laundry detergent composition

A solid free-flowing particulate laundry detergent composition can include a particle, wherein the particle includes a continuous phase and a discontinuous phase, wherein the continuous phase includes fatty material selected from: fatty acid and/or salts thereof; fatty alcohol; and any combination thereof, wherein the discontinuous phase includes: non-ionic and/or anionic emulsifier surfactant; hydrophobized polyethylene glycol polymer; silicone and/or petrolatum; and perfume.

Solid free-flowing particulate laundry detergent composition

The present invention relates to a process for preparing a spray-dried laundry detergent particle, wherein the process includes the step of contacting zeolite to monomeric organic carboxylic acid in an aqueous mixture, wherein the aqueous mixture has a pH of 4.2 or less, wherein the aqueous mixture includes detersive surfactant, wherein the aqueous mixture is substantially free of silicate salt, and wherein the aqueous mixture is substantially free of carbonate salt, wherein the zeolite reacts with the monomeric organic carboxylic acid to form silica, wherein the aqueous mixture is spray-dried to form a spray-dried laundry detergent particle, wherein the particle includes: detersive surfactant; monomeric organic carboxylic acid; and silica, wherein the particle is substantially free of silicate salt, and wherein the particle is substantially free of carbonate salt.

Process for preparing a spray-dried laundry detergent particle

The present invention relates to gels comprising lamellar phase compositions and water-soluble unit dose articles comprising said gels.

The present invention provides a multi-compartment laundry detergent water-soluble pouch, wherein the pouch comprises a first compartment and a second compartment, wherein the first compartment comprises a benefit delivery composition, wherein the second compartment comprises a detergent ingredient, wherein the benefit delivery composition comprises a lamellar phase composition and a viscous hydrophobic ingredient, wherein the lamellar phase composition comprises a mixture of surfactant and fatty amphiphile in lamellar phase, wherein the viscous hydrophobic ingredient comprises silicone and/or petrolatum.

Lamellar phase-containing laundry detergent in a multi-compartment water-soluble pouch

A method for quantifying the soil dispersion capacity of a cleaning product or component thereof where the method comprises the following steps:

Measurement method

The present invention relates to a colored particles and to detergent compositions containing them that can be used to impart a hueing effect to fabrics contacted with these colored particles in aqueous solution. The invention enables the effective hueing while alleviating problems of staining or spotting by combining in the color particle, hueing agent, preferably pigment, binding agent and suspending agent.

Detergent compositions comprising coloured particles

Rinse-aid composition comprising a polyalkoxylated trisiloxane surfactant and a non-ionic solubilising system having a cloud point above room temperature and an acidifying agent wherein the rinse-aid composition has a pH of from about 1 to about 4.5.

Rinse-aid composition comprising a magnesium salt and zinc salt mixture

A process for preparing detergent particles having a coating layer of water-soluble inorganic material is provided. The detergent particle comprises a particle core of a detergent active material. This particle core is then at least partially covered by a particle coating layer of a water soluble inorganic material. Particularly preferred are non-hydrate inorganic coating materials including double salt combinations of alkali metal carbonates, and sulfates. The particle coating layer may also include detergent adjunct ingredients such as brighteners, chelants, nonionic surfactants, co-builders, etc. The process includes the steps of passing the particle core through a coating mixer such as a low speed mixer of fluid bed mixer and coating the particle core with a coating solution or slurry of the water soluble inorganic material. Upon drying, the resultant detergent particles have improved appearance, flow properties, and improved solubility, and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.

Process for producing coated detergent particles

The present invention relates to a cationic particle containing an aqueous cationic surfactant solution adsorbed to a water-insoluble high absorbing material.
