A method of making a nail polish comprising using a rotor-stator to prepare a suspension base by mixing dry clay and film forming material in a solvent or solvent mixture to make a clay gel, allowing the resultant clay gel to thicken, and letting the thickened clay gel down in additional solvent, film forming polymer, and plasticizer and then adding pigment paste. The rotor-stator can be used before and/or after adding the pigment paste or can be used to make the pigment paste itself. Nail polish cosmetic compositions, UV curable cosmetic nail gel compositions, and nails coated with the compositions.

Nail polish composition and method of making a nail polish

A continuous process for preparing polymers, preferably emulsion polymers, with minimal fouling of the reactor is provided. The process is effected in a reactor which does not contain a gas phase, optionally by reducing the gas content of the reaction mixture.

Continuous process for preparing polymers

A continuous process for preparing polymers in a non-cylindrical heat exchanger is disclosed. The amount of monomer fed and polymer in the reactor is controlled to minimize fouling of the reactor. The use of steam to control the temperature of the reaction mixture is also disclosed.

Reduction of polymer fouling on reactor surface in a continuous process for preparing polymers

This invention relates to a process for stripping polymer reaction compositions. The process reduces gel in the polymer reaction composition by adjusting the pH of the polymer to from 7 to 11 prior to stripping and maintaining the adjusted pH during stripping, maintaining the temperature of the polymer at from 30&deg; C. to 70&deg; C. during stripping, utilizing a continuous stripping operation, or combinations thereof.
