Disclosed is a novel compound and a process of preparing it. It has been shown to have anti-inflammatory activity and can be utilised in a wide range of cosmetic compositions. The compound is a 2(1H)-pyridinone of formula (1) in amide or enol form. It may be prepared by exposing a solution of piroctone olamine in an organic solvent or in water comprising at least one surfactant to UV radiation to degrade the piroctone olamine. The compound of formula (1) is separated from the degradation products by chromatography.

2(1H)-pyridinones and their use to treat inflammatory conditions

According to one embodiment of the present disclosure, a reclaim cylinder includes: a single housing () coupled to a fiber draw furnace system, the housing defining a reclaim chamber, a plurality of gas reclaim ports () spaced equidistant from each other and tangentially coupled to the housing, a gas sampling port () tangentially or perpendicularly coupled to the housing, and a particle sampling port () tangentially or perpendicularly coupled to the housing.

Disclosed is a hair care composition comprising a compound of the formula (1) and a photolabile antidandruff agent wherein said photolabile antidandruff agent is piroctone olamine. The compound of formula (1), which is a 2(1H)-pyridinone, may be a degradation product of piroctone olamine on exposure to UV radiation and has been shown to improve the stability of piroctone olamine.

Hair care composition comprising piroctone olamine

This invention relates to a hair care composition more particularly to a wash-off composition, especially preferred being a shampoo or a conditioner, which provides the desired anti-dandruff efficacy with enhanced stability of the active materials on hair/scalp during use. This is achieved through a judicious combination of an organic UV filter, a zinc compound and selective anti-dandruff agent. The composition comprises 0.01 to 3% by weight zinc pyrithione, an organic UV filter and 0.1 to 5% by weight additional zinc compound. The weight ratio of zinc compound to zinc pyrithione is over 3:1.
