 This allows the product to weakly adhere to people and windows, for instance, but easily be cleaned up without the string falling apart or staining inert surfaces.The current formulation is not published, but one of the primary recipes in the original patent calls for 12.2% of the synthetic resin poly(isobutyl methacrylate) by weight.It additionally calls for 0.5% of the selected plasticizer, dibutyl phthalate, 2.5% of sorbitan trioleate surfactant, 0.35% silicon fluid such as dimethyl siloxane or methyl phenyl siloxane, 5.6% of flame retardant hexabromobenzene, and 2–3% pigment (all percentages by weight).
