Abstract
Abstract This invention relates to a gel composition comprising water, mineral oil and two polyoxyethylene-polyoxybutylene block copolymers designated copolymer A and copolymer B wherein said block copolymers are cogeneric mixtures of conjugated polyoxybutylene-polyoxyethylene compounds containing in their structure oxybutylene groups, oxyethylene groups and an organic radical derived from a water-soluble organic compound containing a plurality of reactive hydrogen atoms and 2 to 12 carbon atoms wherein copolymer A has a molecular weight of the polyoxybutylene portion of at least about 1800 and the polyoxyethylene portions contribute from about 60 to 80 percent by weight of the compound and copolymer B has a polyoxybutylene portion with a molecular weight of at least about 600 and the polyoxyethylene portion contributes from about 20 to 40 percent by weight of the compound.
