Uses

Different sources of media describe the Uses of 637-12-7 differently. You can refer to the following data:
1. Waterproofing fabrics, ropes; in paint and varnish driers; thickening lubricating oils; in cements; in light-sensitive photographic compositions.
2. aluminum stearate is a saline form of stearic acid used as a thickener and emulsifier, and to regulate the stability and suspension of a cosmetic formulation.
3. Aluminum stearate is used for waterproofing fabrics and for thickening lubricating oils. It is involved in the preparation of polyamides and thermosetting plastics. It is used as a waterproofing additive in cements and in light-sensitive photographic compositions. It acts as a gelling agent for alkyd paints, as a defoamer for oil drilling fluids and as a retarder for polysulfide dental impression materials. Further, it is used in greases, lubricants, cutting compounds, cosmetics and pharmaceuticals. It serves as a flatting agent, as a defoaming agent in beet sugar and yeast processing. In addition to this, it is used as a water-repellent soap for natural stone surfaces.

STABLE SOLUBLE SALTS OF PHENYLBENZIMIDAZOLE SULFONIC ACID AT PHS AT OR BELOW 7.0

The invention concerns preparations, particularly cosmetic or pharmaceutical/dermatological preparations, containing phenylbenzimidazole sulfonic acid (i.e. 2-phenylbenzimidazole-5-sulfonic acid) neutralised with basic amino acids such as arginine, lysine, ornithine and histidine so that the pH of the preparation can be at or below 7.0 without incurring crystallisation of the phenylbenzimidazole sulfonic acid.

Compound for the treatment of bovine mastitis

Compositions for the treatment of bovine mastitis are provided. Said compositions comprise as active compound [2-carboxy-4-/2'-(5'-nitrofuryl)]quinoline N-oxide. The method is performed in such a manner that the composition is administered to the animal, preferably by way of intramamary infusion.
