Abstract
A composition for removal of adhesives comprises a polar solvent, such as benzyl alcohol, in combination with thickeners, dry lubricants, and/or gelling agents to allow for penetration of the adhesive and transformation of the treated adhesive into a solid material that can be readily removed from a surface without forming sticky residue that adheres to the solid material or tool used to remove the adhesive.
Claims20
A composition for removal of an adhesive, comprising:
- a liquid phase comprising an organic solvent;
- and
- a solid phase dispersed in the liquid phase, the solid phase comprising a thickener, a dry lubricant, and a gelling agent;
- wherein the composition optionally comprises a surface-active agent.

A method of forming a dry non-tacky material from an adhesive treated with an organic solvent composition, the method comprising:
- combining an organic solvent, a thickener, a dry lubricant, and a gelling agent to form the organic solvent composition;
- applying the organic solvent composition to the adhesive to form the dry non-tacky material;
- wherein the thickener is present in the organic solvent composition an amount of from about 40 to about 50 wt. %, wherein the dry lubricant is present in the organic solvent composition in an amount of from about 3 to about 10 wt. %, and
- wherein the gelling agent is present in the organic solvent composition in an amount of from about 1 to about 3 wt. %, each based on a total weight of the composition.
