摘要:
Ionic and ionogenic comb copolymers are disclosed along with personal care products that employ them as a modifier that results in increased sensory attributes and increased effectiveness in the deposition of actives and can also act as a thickening agent. The copolymer includes one or more repeating units derived from olefinically unsaturated anionic or anionogenic or zwitterionic comonomers, and one or more repeating units having the formula in which Y is a moiety forming part of a copolymer backbone, Z is a moiety that exhibits association with other Z moieties or with other moieties within the ultimate formulation in which the copolymer will be employed, and b is a bond or moiety that links the Z moiety to the Y moiety. In certain embodiments, the copolymer also includes repeating units derived from acrylamide monomers, olefinically unsaturated hydrophilic monomers or other olefinically unsaturated monomers.

A microcapsule composition useful in delivering an active material contains an oil core and a microcapsule wall encapsulating the oil core. The microcapsule has a zeta potential of 10 mV or greater, the microcapsule wall is formed of an encapsulating polymer, and the oil core contains an active material. Also disclosed are consumer products containing such a microcapsule.
摘要:
A hair care product comprising 100% plant derived, biodegradable solid granules that sustain beneficial essential oils or herbal extracts that emulsify in water to create an emulsified therapeutic solution is disclosed. The hair care product improves over existing liquids in that its solid granule form is completely plant derived and biodegradable and can sustain essential oils and antioxidants without the requirement of chemical preservatives, and can be packaged in eco-friendly water soluble film and compostable paper. It improves over existing solid forms in that it is a 100% water soluble granule that emulsifies easily in water to form an easy to use liquid product.

摘要:
Antimicrobial cationic polymers having one or two cationic polycarbonate chains were prepared by organocatalyzed ring opening polymerization. One antimicrobial cationic polymer has a polymer chain consisting essentially of cationic carbonate repeat units linked to one or two end groups. The end groups can comprise a covalently bound form of biologically active compound such as cholesterol. Other antimicrobial cationic polymers have a random copolycarbonate chain comprising a minor mole fraction of hydrophobic repeat units bearing a covalently bound form of a vitamin E and/or vitamin D2. The cationic polymers exhibit high activity and selectivity against Gram-negative and Gram-positive microbes and fungi.

摘要:
The present invention relates to a composition for dyeing human keratin fibres, such as the hair, which is free of oxidizing agent other than atmospheric oxygen and which is in cream form, comprising: (a) at least one oxidation dye precursor; (b) at least one ionic surfactant; (c) at least one oil; (d) optionally at least one solid fatty alcohol in a content of not more than 0.5% by weight relative to the weight of the composition; (e) at least one thickening polymer. The invention also relates to a process for dyeing human keratin fibres, in which this composition is applied to the said fibres, in the presence of at least one oxidizing agent other than atmospheric oxygen, and also to a multi-compartment device that is suitable for performing this process.

摘要:
The present invention concerns compositions that comprise alcohol-free microemulsions and methods for their use that include a surfactant, a lipophilic linker, and/or a hydrophilic linker. These compositions can be used, for example, in cosmetic or hair applications. In certain aspects, compositions of the invention have the ability to microemulsify sebum while providing enhanced cleansing of cosmetic products from the skin or hair. In addition, the compositions have the ability to enhance the penetration of skin or hair active ingredients, such as emollients, humectants, anti-oxidants, lipids, vitamins, botanicals, dyes, tanning compounds, etc.
