Abstract
Abstract An aqueous or gel cleaning composition is provided which comprises approximately by weight (a) 0.02 to 25.0% of at least one nonionic cleaner; (b) 0.01 to 10% of a diglycol carbonate monomer; (c) 0.01-10.0% of an antifog agent; (d) up to 25% of a lower aliphatic alcohol; (e) up to 1.0% of a preservative agent; (f) the balance water and if a gel is desired 0.1 to 5.0% of a thixotropic gelling agent.
