Abstract: An acid pH, clear shampoo formulation containing a solubilized cationic resin in a detergent system maintained within a pH range of approximately 4 to 6.7, is described. Dilution of the clear shampoo formulation during the hair washing operation causes precipitation of an anionic/cationic complex which plates out on the hair and provides more facile combing of freshly shampooed hair. Tangles, pulled-out hair and other discomforts normally encountered with hair shampooing are minimized. The acid pH, clear shampoo formulation of this invention is especially beneficial for damaged, bleached, or cold-waved hair. The deleterious effects of shampooing damaged hair with alkaline detergent systems are avoided by maintaining the clear shampoo formulation within the acid range.

Abstract: Reinforced silicone elastomers, having improved tensile strength and particularly tear strength, include at least copolymers of aryl siloxanes and alkyl siloxanes, in a particular ratio of aryl to alkyl substituents, having reflective indices matched to the index of refraction of a silicone filler, forming optically clear material, useful for soft contact lenses.FIELD OF THE INVENTIONThis invention relates to optically clear, reinforced, inter-polymers of aryl and alkyl siloxanes, forming silicone elastomeric, soft plastic contact lenses.BACKGROUND OF THE INVENTIONMany silicone elastomers, when unfilled, generally have excellent optical clarity and are usually water white in color. The tensile strength, and especially the tear strength, of such elastomers is poor, however. By filling the elastomers with fine particulate solids, the silicone gum stock will produce, when vulcanized and cured, an elastomer with much improved strength.

Abstract: An improved composition and method for detecting fibrinogen, fibrinogen split products and/or fibrin split products in blood comprises utilizing killed, dyed Staphylococcus aureus cells which can be prepared by either of two methods. In the first method, Staphylococcus aureus organisms are incubated in a nutrient medium containing a polyalkylene glycol having a molecular weight of from 1000 to 5000 to which is added triphenyltetrazolium chloride; the growing organisms reduce the triphenyltetrazolium chloride to triphenylformazan which imparts coloration to the cells; the dyed Staphylococcus aureus cells are killed and substantially all untrapped dye is removed. In an alternate method, a suspension of Fast Black Salt K is added to a suspension of killed Staphylococcus aureus cells, and the dyed cells which result are washed to remove substantially all unfixed dye. The killed, dyed Staphylococcus aureus cells prepared by either method are suspended in an imidazole buffer to maintain a pH of 7.4.
