Disintegrating particles and cleanser or detergent composition

A disintegrating particle, comprising:

• i) primary particles, wherein at least a portion of the primary particles are insoluble in water, wherein said primary particles which are insoluble in water are selected from the group consisting of polyethylene, polypropylene, polyamide, polyethylene terephthalate, polystyrene, polyurethane, sodium poly(meth)acrylate, poly(meth)acrylic esters, rubbers, and cross-linked derivatives thereof or selected from the group consisting of chitosan, fruit shells, bentonite, talc, mica, kaolin, sepiolite, silica, calcium carbonate, titanium oxide, silicic acid anhydride, hydroxy calcium apatite and pearl powder;
• and
• ii) a water soluble binder, wherein
• said primary particles are agglomerated by said water soluble binder, the average particle diameter of the primary particles is at most 70 μm, the average particle size of said disintegrating particle ranges from 150 to 360 μm, the rate of disintegration of the disintegrating particle in 10% saline solution is 6.8% to 22.9%, and
• at least 60 vol. % of the particles are disintegrated in an aqueous solution containing sodium chloride at a concentration lower than 1.5% wt. %.
