Disclosed are oral care compositions having reduced tooth staining propensity and comprising in a pharmaceutically acceptable carrier, a cationic antimicrobial agent and an anti-stain agent comprising one or more materials from each of at least two of the following chemical groups: Group 1. anionic agents, Group 2. aldehydes, ketones, and other reactive carbonyl compounds and Group 3. nonionic ethoxylated surfactants.

Examples of cationic antimicrobial agent include quaternary ammonium compounds such as cetylpyridinium chloride, cetyl pyridinium fluoride, tetradecylpyridinium chloride, N-tetradecyl-4-ethyl pyridinium chloride and domiphen bromide; chlorhexidine; and metal ion sources to supply metal ions such as stannous, zinc or copper.

Antimicrobial compositions are described comprising a least one biguanide compound and at least one hydrocarbon surfactant comprising a saturated or unsaturated C.sub.2-C.sub.4 diol moiety and optionally further comprising alkoxy groups. In some embodiments, the composition further comprises an aqueous or hydrophilic liquid carrier. In favored embodiments, the diol surfactant is present in an amount such that the antimicrobial activity of the biguanide antimicrobial compound is improved. Also described are articles comprising the described antimicrobial composition and methods of use of the antimicrobial composition.

A valve structuring designed for use in all water installations, water inlets for houses, kitchen installations and embedded shower filters as a stop valve, in the areas to perform on-off control, in faucets with the purpose of providing water savings and to use in domestic and industrial type kitchen faucets as a stop valve. The valve is designed for use as an on-off valve in air installations that operate with air.
