Abstract
The invention relates to a thickened preparation comprising a polymer which can be obtained by radical emulsion polymerization of at least one acidic vinyl monomer or salt thereof, at least one non-ionic vinyl monomer, in particular preferably a hydrophobic non-ionic vinyl monomer, at least one monomer containing an unsaturated terminal group and a polyoxyalkyene portion, at least one crosslinking monomer, optionally a protective colloid, and is characterized in that the polymerization is controlled such that the gelling effect occurs at least at times, which is achieved by the monomer addition (dosing time) taking place for 40 minutes, particularly preferably for 30 minutes.
Claims20
A thickened preparation, wherein the preparation is present as one or more of a cosmetic or dermatological product, a medicinal product, a body cleansing composition, a cream, a shower gel, a household cleaning composition, a paint, an ink, an adhesive, a dispersant, an anti-settling agent, a concrete or cement additive, and a coating composition, and wherein the preparation comprises as thickener one or more polymers which are obtained by free-radical emulsion polymerization of monomers comprising
- (A) at least one acidic vinyl monomer or salt thereof,
- (B) at least one nonionic vinyl monomer,
- (C) at least one monomer comprising an unsaturated end group and a polyoxyalkylene portion,
- (D) at least one crosslinking monomer, and
- (E) optionally, a protective colloid,
- the polymerization being controlled such that at least at times a gel effect arises, achieved by monomer addition (dosing time) taking place over not more than 40 minutes.
