Abstract

A clear, single phase, pre-spotting composition is provided in the form of a microemulsion, solution, or gel and which comprises, by weight: (a) from about 10 to 70% of an organic solvent comprising one or more alkanes having from 10 to 18 carbon atoms; (b) from about 4 to 60% of one or more nonionic surfactants comprising the condensation product of an aliphatic primary or secondary alcohol having from 9 to 16 carbon atoms with from 1 to 7 moles of ethylene oxide per mole of said alcohol; (c) from about 0 to 50% of a supplementary nonionic surfactant comprising an amine oxide or an alkyl phenol ethoxylate, the total amount of nonionic surfactants in the pre-spotting composition being no greater than about 60%; (d) from about 0 to 20%, of a co-surfactant comprising an aliphatic primary or secondary alcohol having from 10 to 18 carbon atoms; (e) from about 0 to 10% of a polar organic co-solvent; (f) from about 1 to 80% water, the respective percentages of each component of the composition being such as to form a clear, single-phase pre-spotting composition which is further characterized by being infinitely dilutable with water without concomitant phase separation such that the addition of water to said pre-spotting composition is an amount of at least one hundred parts water to one part of said composition results in a diluted composition which is entirely in a clear single phase; and (g) the balance optionally comprising a minor amount of adjuvants.
