The invention relates to a process for producing a substantially stable dispersion without manufacturing aids, where the dispersion consists essentially of a hydrophobic plant sterol and an aqueous material, wherein the plant sterol is selected from plant sterols and plant stanols. The process comprises mixing the plant sterol with the aqueous material to form a first dispersion The next steps involve heating the first dispersion to form a heated mixture, followed by homogenizing the heated mixt...

Absorbent articles containing an additive are disclosed. The absorbent articles include an effective amount of an inhibitory compound, such as thiolactomycin or thiomalonate, to substantially inhibit the production of TSST-1 by Gram positive bacteria.

The electrocatalyst composition is composed essentially of platinum present in an atomic percentage ranging between about 30 percent and about 85 percent, titanium present in an atomic percentage ranging between about 5 percent and about 30 percent, a third metal present in an atomic percentage ranging between about 1 percent and about 30 p...

An aqueous solution of metronidazole in which the concentration of metronidazole is higher than 0.75%. The solution contains a combination of solubility-enhancing agents, one of which is a cyclodextrin such as beta-cyclodextrin and the second is niacin or niacinamide. Methods of manufacture and therapeutic use of the solution are disclosed.

A method of controlling or containing radioactive contamination by providing a neutron absorbing material to a radioactive contamination site. Preferably the neutron absorbing material is present as a powder, granule, slurry or suspension, allowing the neutron absorbing material to blanket cover the radioactive contamination site. Suitable neutron absorbing materials include lanthanide elements having a cross section of 100 Barns or greater, as well as hafnium, zirconium, tantalum, silver, indiu...

The corrosion of aluminum-based metal films may be minimized by applying a lactate-containing solution to the aluminum-based metal films before the aluminum-based metal films are etched. The lactate-containing solution is applied to the aluminum-based metal film before the film is etched with a corrosive etchant. Minimizing the corrosion of the aluminum-based film may increase the yield and performance of the highly reflective pixel arrays that are formed from the aluminum-based metal for use in...

Silane-containing polymers are prepared by the polymerization of one or more ethylenically unsaturated monomers in the presence of a silane-containing aldehyde, hemiacetal, or acetal as a regulator, optionally with further regulators as well. The silane-containing regulators produce polymers with superior properties and with improved polymerization parameters as compared to the conventional mercaptosilane regulators.

Monomers for polymers having high oxygen permeability, high water content and a low modulus of elasticity are provided, and polymers and ophthalmic lenses comprised of said monomers are provided. They are monomers represented by formula (1) or (2) below: X--O--(CH.sub.2CH.sub.2CH.sub.2O).sub.m--(CH.sub.2).sub.n--A (1) ##STR00001## wherein, X is a polymerizable group having carbon-carbon unsaturated bonds; A is a siloxanyl group; R is H or a methyl group; m is an integer of 1 to 10; m' is an inte...
