and an ammonium ion that has a polymerizable unsaturated group.
The skin cleanser of the present invention makes it possible to thoroughly wash off oily stains such as makeup articles (lipstick, eye-make, waterproof foundation, etc.) while giving a good feel in use.
A detergent composition containing the following components (A) and (B) is packed in a foamer container 10 provided with a porous membrane:
(A) at least one anionic surfactant having a branched hydrocarbon group selected from phosphate surfactants, sulfate surfactants and sulfonate surfactants; and
(B) at least one nonionic surfactant.
Film-forming compositions, as well as methods of making and using, wherein the compositions include an optional active agent, water, a surfactant, and a water-soluble or water-dispersible vinyl polymer comprising amine group-containing side-chains and a copolymerized hydrophobic monomer; wherein the amine equivalent weight of the polymer is at least about 300 grams polymer per equivalent of amine group.
The present invention relates to an antiseptic composition comprising an antimicrobial agent selected from the group consisting of I2, an iodophor, and a combination thereof, wherein the antimicrobial agent is present in an amount sufficient to provide an available iodine concentration of at least about 0.25 wt-%; a hydroxycarboxylic acid buffer in an amount in excess of 5 wt-%; and water.
Detergents useful for cold-water cleaning and mid-chain headgroup and alkylene-bridged surfactants useful therein are disclosed. The mid-chain headgroup surfactant has a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the alkyl chain. The alkylene-bridged surfactant has a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Preferred surfactants in these classes are alcohol sulfates, alcohol ethoxylates, ether sulfates, sulfonates, arylsulfonates, alcohol phosphates, amine oxides, quaterniums, betaines, and sulfobetaines. Surprisingly, detergents formulated with the surfactants provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.
