The cation exchange resin of the present disclosure may be strongly or weekly acidic and have a variety of functional groups, e.g., weakly acidic type of resin containing carboxylic acid group, or strongly acidic type of resin containing sulfonic functional groups. Generally, the carboxylic ...
you are not alone. Many people are suffering from this disorder. People who have been through a war, natural disaster, or sexual assault may be more likely to develop PTSD. But anyone can have PTSD. Luckily, there are many ways to cope with the...
(b) a reduced odor, particularly ammoniacal from urine waste products; (c) lack of toxicity; (d) low degree of dusting to avoid tracking; (e) and low cost, economically available ingredients of the composition. Natural grasses, such as alfalfa have been employed in the past with a clay...
To find a safer, more environmentally friendly alternative, Reno and her advisor, Richard Wool, Ph.D., who are at the University of Delaware, turned to lignin. They note that papermaking and otherwood-pulping processes produce 70 million tons of lignin byproduct each year, 98 percent of whi...
More particularly, the present invention relates to a new and improved method and device for assaying a liquid, such as urine, for proteins by utilizing a test device having a test pad comprising an indicator reagent composition incorporated into a new and improved carrier matrix. The test pad ...
In a more preferred embodiment, the absorbent property modification polymer is a cationic polymer which can be reactive with at least one component included in a urine. Preferably, the cationic polymer is capable of having an electrostatic interaction with an acidic group such as a carboxyl group ...
When this polymer is exposed to body fluids such as urine at 37° C., it will not degrade as this temperature is above its cloud point (34° C.). However, if the polymer is placed in water at room temperature (23° C.), the polymer will, with time, go back into solution as it...
It often contains plant material (straw or wood shavings) that has been used as bedding for animals and has absorbed the feces and urine. It is often produced by intensive livestock rearing systems. Animal manures may also include other animal products, such as feathers, hairs, bones, blood,...
In addition, dry crosslinking is usually carried out a temperature of over 160° C. Exposing pulp to such high temperature causes the fiber to suffer from more drawbacks, such as yellowing. Another major issue is that the dry cross-linking is carried at low pH using an acidic crosslinking ...
As used herein, the term “absorbent article”, refers to devices which absorb and contain bodily exudates (e.g., BM, urine, blood), and, more specifically, refers to devices which are placed against or in proximity to the body of the wearer to absorb and contain the various bodily exuda...
