During a wash cycle, the compositions deliver softening to the fabrics. The disclosure further provides a method of making a solid particulate composition for fabric treatment including: mixing a water-soluble solid carrier and a buffer system to form a mixture; wherein the solid carrier is an aqueous salt having a water vapor partial pressure at a temperature from about 30° C. to about 100° C. that corresponds to the water vapor partial pressure of a saturated solution of the salt at the same temperature; adding a cationic polymer and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling and shaping the melt into individual particles including melt bodies.

The invention relates to solidification of liquid amine oxide, betaine, and/or sultaine surfactants with a carrier to form a solidified surfactant composition. In particular, the invention relates to solidification of liquid surfactants utilizing drying device(s), wherein the feed composition contains at least one liquid surfactant and a carrier to form a solidified surfactant composition. The solidified surfactant compositions can be useful in various cleaning compositions.

The present disclosure provides compositions for fabric treatment having at least one dye transfer inhibitor (DTI), at least one water-soluble carrier, at least one fragrance, and at least one buffer system, and other optional ingredients. During a wash cycle, the compositions disclosed herein significantly boost color fading protection of fabrics. The present disclosure further provides a method of making a composition for fabric treatment, including mixing a water-soluble carrier and a buffer system to form a mixture; adding a dye transfer inhibitor (DTI) and a fragrance into the mixture; mixing the mixture; heating the mixture and obtaining a melt thereby; and cooling the mixture. The method can further include shaping the melt into individual particles having melt bodies, which can optionally be in the form of a pastille.

The present disclosure provides a method for preparing a microcapsule and a microcapsule prepared thereby capable of selective release of oils and preventing volatilization of oils while maintaining long-term performance by improving storage stability of the oil contained in the capsule.

The present application discloses an environmental friendly detergent tablet, and a preparation method and an tableting equipment thereof, belonging to the field of washing products. An environmental friendly detergent tablet is made of the following raw materials by weight percentage: polyvinyl alcohol, film-forming agent, surfactant, plant starch, co-solvent, bio-enzyme formulation, water softener, and other additives; the preparation method includes the following steps: mixing water, polyvinyl alcohol and film-forming agent under stirring, heating to 80° C-90° C., and continuing stirring to obtain an initial mixed slurry; adding a co-solvent into the initial mixed slurry, then adding a surfactant, then adding a plant starch, under stirring, to obtain a mixed materials; drying the mixed materials, coating with the bio-enzyme formulation, molding, and slicing to obtain the environmental friendly detergent tablet.
