Abstract: The invention relates to a transparent microemulsion comprised of a surfactant or emulsifier based on polyethylene glycol, a first cosurfactant (or coemulsifier) based on polyglycerol, a second cosurfactant (or coemulsifier) based on monoesters, an aqueous or hydrophilic phase, and may or may not include an active for delivery that can include vitamins, sunscreens, antiaging agents, or pharmaceutical actives. The said microemulsion is useful in personal care and pharmaceutical products.

Abstract: A composition formulated from a primary anionic surfactant; optionally a secondary surfactant and/or a resin; and a nitrogen-containing compound of the structural formula: 1

Abstract: A microemulsion for use in personnel care products, home care products and fabric care products which is clear and has particle sizes that are less than the wavelength of light, said microemulsion comprising, as essential components; (a) a substantially water insoluble quaternary ammonium salt containing at least one long-chain aliphatic C8-24 hydrocarbon group; (b) an oil or hydrophobic organic compound that is not dispersible in water on its own; and (c) a dispersant capable of preventing component (b) from coalescing into particle sizes that are above the wavelength of light, wherein the weight ratio of component (a) to component (b) to component (c) is from 2:0.5:0.4 to about 0.5:2:0.8. A clear, indefinitely dilutable microemulsion is obtained by quenching the same in water.

Abstract: A composition formulated from a primary anionic surfactant; optionally a secondary surfactant and/or a resin; and a nitrogen-containing compound of the structural formula: wherein R is a saturated, linear, branched or cyclic alkyl or aryl group containing 12 to 22 carbon atoms, with the proviso that R contains at least 80% of a single chain length and R is not lanolin, wheat germ or other natural broad-based chain distribution oil, R1 is a saturated or unsaturated, linear, branched or cyclic alkyl or aryl group containing 1 to 6 carbon atoms and may contain one or more hydroxyl groups, R2 is selected from the group consisting of hydrogen, methyl, ethyl and benzyl; and A− is a monovalent anion.

Abstract: A composition comprising: (a) a compound of the following structural formula: wherein each of R* and R** is independently a linear, branched or cyclic alkylene group containing 2 to 12 carbon atoms, wherein no two nitrogen atoms are separated by fewer than 2 carbon atoms; each of A1, A2, A3, A4, and A5 is independently a straight or branched alkylene containing 2 to 4 carbon atoms; each of R1, R2, R3, R4, and R5 is independently —H or RAC(O)— wherein RA is straight or branched alkyl or alkenyl containing 7 to 21 carbon atoms and 0 to 4 carbon-carbon double bonds; provided that at least one of R1, R2, R3, R4, or R5 is RAC(O)—; each of Q1, Q2 and Q3 is independently —H, —CH3, —C2H5, —C3H7, —C4H5, benzyl, —CH2COOH, or —CH2COOA−; or, if R* is a —CH2CH2— group, Q1 and Q3 together or Q1 and Q2 together may be a —CH2CH2— group to form a six-membered piperazine ring; or, if R** is a —CH2CH2— group,
