摘要:
A self-reversible reverse microlatex composition comprising an oil phase, an aqueous phase, a water-in-oil surfactant(s), a oil-in-water surfactant(s) and 15% to 40% by weight by weight of a branched or crosslinked polyelectrolyte. The polyelectrolyte is based on a monomer containing a strong or weak acid function, which is partially or totally salified, a copolymer of at least one monomer containing a strong acid function and at least one monomer containing a weak acid function or at least one neutral monomer, a copolymer of at least one monomer containing a weak acid function and at least one neutral monomer, or a copolymer of at least one monomer containing a strong acid function, a monomer containing at least one weak acid function and at least one neutral monomer. The surfactants have a total HLB number of 8.5 to 11. Uses in cosmetics and as an industrial emulsifier and/or thickener.

The present invention relates to a rinse-off antimicrobial cleansing composition comprising from about 0.1% to about 5.0%, by weight of the cleansing composition, of an antimicrobial active; from about 6% to about 16%, by weight of the cleansing composition, of an anionic surfactant, wherein at least about 67% of the anionic surfactant is selected from the group consisting of Class A surfactants, Class C surfactants, and mixtures thereof, wherein the ratio of Class A surfactant to Class C is from about 100:0 to about 1.5:1; from about 2% to about 4%, by weight of the cleansing composition, of a proton donating agent having a Biological Activity Index, Z, of greater than about 0.75, wherein the proton donating agent is such that the composition is essentially free of C.sub.4 -C.sub.20 alkyl fatty acid, and wherein from about 0.15% to about 2%, by weight of the cleansing composition, of the proton donating agent is salicylic acid; a mildness enhancing agent selected from the group consisting of from about 20% to about 70%, by weight of the anionic surfactant, of a mildness enhancing cosurfactant; from about 0.1% to about 1.0%, by weight of the cleansing composition, of a mildness enhancing polymer; and mixtures thereof, and from about 35% to about 95.75%, by weight of the cleansing composition, of water; wherein the composition is adjusted to a pH of greater than about 3 and less than about 6. The invention also encompasses methods for cleansing skin and providing residual effectiveness versus Gram negative bacteria using these products.
摘要:
The present invention relates to a cosmetic or dermatological composition comprising an emulsion of oil-in-water type formed of oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase. Each oily globule containing at least one lipophilic compound which is cosmetically or dermatologically active is individually coated with a monolamellar or oligolamellar layer obtained from at least one lipophilic surface-active agent, from at least one hydrophilic surface-active agent and from at least one ionic amphiphilic lipid imparting to the emulsion a pH ranging from 5.5 to 7.5, the coated oily globules having a mean diameter of less than 500 nanometers.
摘要:
A sprayable or solid biodegradable wax carrier for insect pheromones and a method for constant release rate of the pheromone from the biodegradable wax. A composition comprising a pheromone and paraffin wax formulated as an aqueous emulsion or a solid suitable for application to a surface of a tree or crop for mating disruption of insect pests. Pheromone is released by diffusion or by partitioning from the biodegradable wax carrier or by pheromone exposure due to the biodegradable wax carrier degradation.
摘要:
Adjuvants for systemic fungicides in the form of a stable microemulsion comprise water, a mixture of methyl esters of fatty acids obtained by the transesterification of vegetable oils, an anionic surface-active agent, at least one non-ionic surface-active agent with an HLB of between 13-18 and a cloud point of >65.degree. and at least one non-ionic surface-active agent with an HLB of between 10 and 12. These adjuvants, which can additionally contain conventional components and/or formulation additives, improve the activity of systemic fungicides belonging to different chemical groups.
摘要:
Novel, stable, cold water-dispersible preparations of fat-soluble substances contain a water-soluble or water-dispersible lignin derivative as the matrix component. These preparations are manufactured by preparing an aqueous emulsion of the fat-soluble substance(s) and the water-soluble or water-dispersible lignin derivative and, if desired, converting this emulsion into a dry powder. The preparations in accordance with the invention can be used not only for animal nutrition but also for human nutrition.
