Graffiti removal system

Abstract

A graffiti removal system and a method of removing graffiti are provided.The graffiti removal system comprises a liquid comprising 4-50 wt % glyceride wherein the glyceride is the condensation reaction product of at least 1.10 moles of a mixture of acids to no more than 2.1 moles of the mixture of acids per mole of glycerin. The mixture of acids comprises at least 0.275 to no more than 0.990 moles of a first acid comprising a branched acid with 16-20 aliphatic carbons; at least 0.250 to no more than 0.810 moles of a second acid comprising an alkyl acid with 9-11 carbons and at least 0.250 to no more than 0.810 moles of a third acid comprising an alkyl acid with 7-9 carbons. The third acid has a lower molecular weight than the second acid. The graffiti removal system also has 6-45 wt % surfactant, optionally up to 5-90 wt % graffiti removal agent and up to 90 wt % solvent. The liquid has a BYV of at least 50 dyn/cm2.
