A two-phase low solvent anionic water-in-oil detergent emulsion to be applied to fabrics as laundry pre-spotting compositions. The composition is characterized by from 1% to 30% by weight of a salt; from about 1 to about 35% by weight of a mixture of about 0.1 % to 2% by weight of a sorbitan nonionic surfactant and from about 0.5% to 30% by weight of at least one other nonionic surfactant and with soluble anionic surfactants. The composition has an HLB of from about 8 to about 14 and is poised at the phase inversion point of an oil-out/water-out emulsion. The composition also includes from about 2% to 60% by weight of a solvent. The balance of the composition is comprised of preferably deionized water.
A container sealing latex composition is formed from a carboxylated styrene butadiene elastomer wherein the carboxyl groups are preferably provided by methacrylic acid, and the composition is substantially free of active cross linking agent and preferably includes latent cross linking agent and stabiliser such as casein, rosin acid, styrene maleic anhydride copolymer or fatty acid.
