The present invention relates to the provision of salt-sensitive particles capable of improving the feeling of effects at the time of use of an oil agent to be blended in a cleaner or the like and a method for producing the same, and so on.

The present invention provides the following [1] to [4].

[1] Salt-sensitive particles containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol, wherein the oil agent is dispersed in the salt-sensitive particles.
[2] A cleaner containing the salt-sensitive particles as set forth in [1].
[3] A method for cleaning a skin, a hair, or a clothing, including using the cleaner as set forth in [2].
[4] A method for producing the salt-sensitive particles as set forth in [1], including a step of preparing an emulsion composition containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol; and a step of removing the water from the emulsion composition.

An automatic dishwashing composition is provided including a builder; a phosphonate; a nonionic surfactant; and a dispersant polymer comprising: 60 to 98 wt % of structural units of formula I

##STR00001## wherein each R.sup.1 is independently selected from a hydrogen and a —CH.sub.3 group; and 2 to 40 wt % of structural units of formula II

##STR00002## wherein each R.sup.2 is independently selected from a —C.sub.1-4 alkyl group and wherein each R.sup.3 is independently selected from a hydrogen and a methyl group.

The present invention relates to a process for producing microcapsules each including a core-shell type structure having a core portion containing at least one functional compound and a shell portion, the process including: step (1): mixing at least one functional compound, a water-soluble monomer (monomer (A)), a crosslinkable monomer having two or more (meth)acryloyl groups (monomer (B)), an oil-soluble polymerization initiator, an organic chain-transfer agent, and water, to obtain a monomer emulsion; and step (2): heating the monomer emulsion obtained in the step (1) to polymerize the monomers, thereby obtaining microcapsules, the organic chain transfer agent having a ClogP value of 3 or less.

The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

Solid detergent compositions designed to maintain solid integrity throughout production of the pressed solid, during mechanical conveying and during ejection from molds, are disclosed. Solid detergent compositions having unexpected immediate block hardness without a curing step are provided by inclusion of a hardness additive composition comprising a synergistic ratio of polycarboxylic acid polymer chelants to aminocarboxylate chelants. Methods of making solid detergent compositions and solid detergent compositions having at least substantially similar cleaning performance to solid detergent compositions without the hardness additive composition are also provided.

Detergent compositions designed to prevent aluminum discoloration while providing high cleaning performance on soils and stains are disclosed. Detergent compositions substantially free of nitrilotriacetic acid (NTA) are disclosed. Methods of using the detergent compositions are also disclosed.

An automatic dishwashing composition is provided including a builder; a phosphonate; a nonionic surfactant; and a dispersant polymer, comprising: 10 to 65 wt % of structural units of formula I ##STR00001##
wherein each R.sup.1 and R.sup.2 is independently selected from a hydrogen and a C.sub.1-3 alkyl group; 10 to 80 wt % of structural units of formula II ##STR00002##
wherein each R.sup.3 is independently selected from a hydrogen and a —C(O)CH.sub.3 group; and 10 to 65 wt % of structural units of formula III ##STR00003##
wherein each R.sup.4 is independently selected from a hydrogen and a —CH.sub.3 group; and wherein at least one of R.sup.1 and R.sup.2 is a C.sub.1-3 alkyl group in at least 1 mol % of the structural units of formula I in the dispersant polymer; wherein the dispersant polymer has a lactone end group and wherein the dispersant polymer has a weight average molecular weight of 1,500 to 6,000 Daltons.

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.

An automatic dishwashing composition is provided, comprising: builder; nonionic surfactant; first dispersant polymer comprising: 60 to 98 wt % of structural units of formula I, wherein each R.sup.1 is independently selected from a hydrogen and a —CH.sub.3 group; and 2 to 40 wt % of structural units of formula II, wherein each R.sup.2 is independently selected from a —C.sub.1-4 alkyl group and wherein each R.sup.3 is independently selected from a hydrogen and a methyl group; and second dispersant polymer comprising: 60 to 98 wt % of structural units of formula I; wherein each R.sup.1 is independently selected from a hydrogen and a —CH.sub.3 group; and 2 to 40 wt % of structural units of formula II; wherein each R.sup.2 is independently selected from a —C.sub.1-4 alkyl group and wherein each R.sup.3 is independently selected from a hydrogen and a methyl group; wherein the first dispersant polymer and the second dispersant polymer are different.
