An oral care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having a front surface and an opposite rear surface. A plurality of tooth cleaning elements may extend from the front surface of the head. A soft tissue cleaner may be located on the rear surface of the head, the soft tissue cleaner including a protuberance field. A first electrode and a second electrode are each operably coupled to a power source to have opposite electrical charges. The first and second electrodes may be spaced apart from one another and substantially surround the protuberance field. In other embodiments, the first and second electrodes may be embedded within or otherwise located within the protuberance field.

A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest.

A mild personal care composition that contains an effective amount of a glycolipid biosurfactant, an amphoteric surfactant and is free of thickeners. The glycolipid biosurfactant may be a rhamnolipid or a sophorolipid surfactant that provides good cleansing properties and exhibits consumer desired foam properties. The glycolipid surfactant may be a mixture of sophorolipid surfactants having a hydrophilic/lipophilic balance (HLB) of about 2 to about 7 and an HLB of about 15 to about 20. The composition also includes a sulfate-free anionic surfactant, an amphoteric surfactant and a dermatologically acceptable carrier.

Hypotonic microbicidal compositions including an antimicrobial, such as an antiviral compound, and a pharmaceutically acceptable carrier in a solution formulation having hypotonic osmolarity have been developed for administration rectally to the gastrointestinal mucosa. In a preferred embodiment for use in preventing or decreasing HIV infection, the microbicidal is tenofovir, or a prodrug or derivative thereof. The formulations may include additional agents such as surfactants to enhance cleansing, buffers, or preservatives. Polymers may be included for osmolarity as well as comfort.

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

A composition for the treatment of grey and damaged hair that contains collagen, Hydroxyethylcellulose, Polyquaternium 7, Aloe Vera, Dextropantothenyl Alcohol, Elastin Hydrolyzate, Sodium Hyaluronate, Keratin, Citric Acid, Preservative, Fragrance and Deionized Water. The composition can be formulated in aqueous form or as a cream and allows to tint and delay grey hair, restoring the natural color of the hair, activating it and forming reflections, achieving a revitalizing effect on the hair in a very short treatment time.
