(canceled) This patent application claims priority of a provisional application, U.S. Ser. No. 60/318,536 which was filed on Sep. 10, 2001.This invention relates to silicone hydrogels that contain internal wetting agents, as well as methods for their production and use.Contact lenses have been used commercially to improve vision since at least the 1950s. The first contact lenses were made of hard materials and as such were somewhat uncomfortable to users. Modern lenses have been developed that are made of softer materials, typically hydrogels and particularly silicone hydrogels. Silicone hydrogels are water-swollen polymer networks that have high oxygen permeability and surfaces that are more hydrophobic than hydrophilic. These lenses provide a good level of comfort to many lens wearers, but there are some users who experience discomfort and excessive ocular deposits leading to reduced visual acuity when using these lenses. This discomfort and deposits has been attributed to the hydrophobic character of the surfaces of lenses and the interaction of those surfaces with the protein, lipids and mucin and the hydrophilic surface of the eye.Others have tried to alleviate this problem by coating the surface of silicone hydrogel contact lenses with hydrophilic coatings, such as plasma coatings Uncoated lenses having low incidences of surface deposits are not disclosed.Incorporating internal hydrophilic agents (or wetting agents) into a macromer containing reaction mixture has ...

Humectant compositions that effectively increase moisture retention in soil and associated methods for identifying same

A method for increasing moisture retention in a soil includes applying an effective amount of an effective humectant composition to the soil. The effective humectant composition is identified by determining the average moisture content of the soil for the humectant compositions applied at a minimum humectant concentration level, a maximum humectant concentration level, and at a first concentration level between the minimum and the maximum humectant concentration level. An average slope curve is generated by plotting the determined average moisture content of the soil for each applied humectant concentration levels from the minimum humectant concentration level to the maximum humectant concentration level. An effective humectant composition is determined when the generated average slope curve provides an increasing average moisture content along the entirety of a length of the generated average slope curve and when the generated average slope curve has a p value of 0.05 or less.
