Copolymer A: a copolymer obtained by copolymerization of a monomer (a) represented by formula (1) and a monomer (b) represented by formula (2), in which the copolymerization ratio of the monomer (a) to the monomer (b), a/b=7/3 to 9/1 (by mol), and having a weight-average molecular weight of 400,000 to 700,000. Copolymer B: a copolymer obtained by copolymerization of a monomer (c) represented by formula (3) and a monomer (d) represented by formula (4), in which the copolymerization ratio of the monomer (c) to the monomer (d), c/d=1/4 to 9/1 (by mol), and having a weight-average molecular weight of 20,000 to 90,000.

Surfactant systems and compositions incorporating the same are disclosed for use as cleaning compositions and rinse aid compositions. The solid surfactant systems are prilled, pastilled, flaked or granular solids and are incorporated into solid formulations at high concentrations for both improved performance and manufacturing benefits. The methods of using the solid compositions containing the surfactant systems for cleaning applications and rinse aid applications are also disclosed.

Stable solid compositions employing a water conditioning agent, including hygroscopic species or non-hygroscopic species. In particular, solid compositions combining an ionic surfactant or an amphoteric surfactant with a water conditioning agent, preferably a polyacrylate water conditioning agent, are disclosed. The ionic surfactant or amphoteric surfactant beneficially stabilize the polymer and/or chelant water conditioning agent, preferably a polyacrylate water conditioning agent, to permit formulation into a solid composition and provide stability under harsh conditions, including humid environments. Applications of using the stable solid compositions are also disclosed.

The present invention is to provide a means with which foreign matters remaining on a surface of a polished object to be polished can be sufficiently removed. The present invention relates to a composition for surface treatment for a polished object to be polished, including: a (co)polymer containing a structural unit A having a phosphonic acid group and a divalent (poly)oxyhydrocarbon group or a salt thereof; and water, wherein a content of the structural units A exceeds 50% by mole relative to the total structural units forming the (co)polymer.

Provided is a treating solution for soft contact lenses capable of imparting hydrophilicity and sustainability thereof to a soft contact lens surface. It has been found that a treating solution for soft contact lenses containing a copolymer that contains two kinds of monomers different from each other as constituent units at a specific ratio, and that has a specific weight-average molecular weight can impart excellent hydrophilicity and sustainability thereof.
