Osidic dispersing agent

An aqueous composition, comprising, as a dry weight based on total aqueous composition weight:

• (a) a mineral material in particle form, in a range of from 30 to 75%;
• and
• (b) an aqueous dispersing agent in a range of from 0.02 to 2%, the aqueous dispersing agent comprising:
• water;
• in the water, a polymer (P) prepared by a process comprising radically polymerizing, at a temperature greater than 50° C., a monomer comprising a first anionic monomer (M1) comprising a polymerizable olefinic unsaturation and a carboxylic acid group, optionally in salt form, in a reaction environment comprising hydrogen peroxide, benzoyl peroxide, acetyl peroxide, lauryl peroxide, tert-butyl hydroperoxide, cumene hydroperoxide, ammonium persulfate, an alkali metal persulfate, and/or an azo compound, as a radical-generating compound, optionally as an association comprising a FeII, FeIII, CuI, and/or CuII ion;
• and
• in the water, a derivative(S) comprising (S1) an ose comprising from 3 to 8 carbon atoms, (S2) an ose oligomer comprising from 1 to 10 ose units, and/or (S3) a product resulting from degradation of a saccharide,
• wherein the aqueous composition has a viscosity of no more than 1.140 mPa·s, measured using a Brookfield RVI viscometer at 100 rpm and 25° C.,
• wherein the monomer comprises the first anionic monomer (M1) in at least 50 wt. %, based on total monomer weight,
• wherein the first anionic monomer (M1) is acrylic acid, methacrylic acid, and/or itaconic acid, optionally in salt form,
• wherein the polymer (P) is at least partially neutralized, and
• wherein an S/P ratio of dry weight amounts of the derivative(S) to the polymer (P) in the water is in a range of from 0.6 to 10.
