Disclosed are compositions, methods of treatment using the compositions and methods of preparing the compositions for the treatment of acne vulgaris. The compositions include succinic acid and an API selected from the group consisting of salicylic acid, azelaic acid, picolinic acid, benzoyl peroxide, antibiotic, retinoid and combinations thereof in a pharmaceutically acceptable preparation. The compositions that include the combination of succinic acid and another API produce improved efficacy in treating acne vulgaris.

The present disclosure relates to methods for treating hair, which are particularly useful for repairing, strengthening, and protecting hair from damage. The methods include applying to the hair each of the following components, together, separately, or in any combination thereof, in one or more hair-treatment compositions: (a) at least one amino acid or amino sulfonic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; (b) at least one non-polymeric mono, di, or tricarboxylic acid, and/or a salt thereof, which is present in at least one of the one or more hair-treatment compositions in an amount of at least 0.5 wt. %; and (c) at least one non-taurate surfactant, which is present in at least one of the one or more hair-treatment compositions.

Hair treated with the methods exhibit desirable cosmetic properties such as smoothness, gloss, improved combability, and improved strength and elasticity.

A method of reducing or preventing conversion of plaque to calculus in a companion animal. The method includes orally administering to the companion animal a composition comprising a zinc salt and one or more chelating agents. The zinc salt and/or the chelating agents can be present in an amount from about 0.01% to about 5.0% of the composition.

The object of the present invention is to provide a photocurable composition for a topcoat of nails or artificial nails having excellent glossiness and a colorless and transparent outer appearance.

The present invention is related to a photocurable composition for a topcoat of nails or artificial nails including the following components (A) to (C), including 40 to 70% by mass of trimethylol propane trimethacrylate relative to the total amount of the component (B), and satisfying that a cured product thereof with a thickness of 800 μm has transmittance of 10.0% or higher at a wavelength of 400 nm:

component (A); a (meth)acrylic oligomer;

component (B): a trifunctional (meth)acrylic monomer contained at 50 to 100 parts by mass relative to 100 parts by mass of the component (A); and

component (C): a photopolymerization initiator contained at 1 to 20 parts by mass relative to 100 parts by mass of the component (A).

A chewable composition for teeth-whitening comprising a first region and a second region separated by a barrier layer; the first region comprising carbamide peroxide having water content of about 2% or less, a wetting agent (e.g., glycerin), an anhydrous chewing gum base having water content of about 1% or less, an anhydrous fruit acid, and one or more gum additives; and the second region comprising a chewable composition comprising a gum base, a source of bicarbonate ion, and one or more gum additives. A kit comprising separate chewable compositions corresponding to the first and second regions, and methods for whitening teeth using the chewable composition are also provided.

Compositions comprising one or more chelating agents and optionally zinc ion salts are used to inhibit the growth or biofilm formation in bacteria associated with personal care products such as ophthalmic, pedicure, manicure or podiatric solutions. The compositions of the present application can also comprise gelling agents, antimicrobials, antibiotic or a pH adjuster. The compositions may be in the form of a solution, a gel, a cream, a jelly, a powder, a paste, a lotion, soap and a cleaner.
