Publication number: 20220127194Abstract: A cementitious composition including recycled superabsorbent polymer (RSAP) and a cementitious material. The RSAP has a purity level of at least 85 percent by weight of the RSAP. Also provided is a cementitious composition where the RSAP has substantially low levels of one or more residual drug entities. Also provided is a method for the construction of a self-sealing cement sheath, the method comprising: supplying a self-sealing slurry of a cementitious composition including cementitious material, an aqueous fluid, and RSAP into an underground geological formation, and allowing the self-sealing slurry of the cementitious composition to cure, thereby forming the self-sealing cement sheath.

Patent number: 5635028Abstract: Soft creped tissue paper products comprising papermaking fibers and a crepe facilitating composition are disclosed. The crepe facilitating composition comprises a bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the bonding inhibitor is a quaternary ammonium compound. The use of a bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped papermaking process comprising the addition of the crepe facilitating composition is also disclosed. The crepe facilitating composition offers the potential to improve production capacity.Type: GrantFiled: April 19, 1995Date of Patent: June 3, 1997Assignee: The Procter & Gamble CompanyInventors: Kenneth D.

Patent number: 4673402Abstract: The present invention provides absorbent articles, such as disposable diapers, which utilize substantially water-insoluble hydrogel material to enhance the absorbent capacity of such articles. In these articles, the hydrogel material, combined in particulate form with hydrophilic fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, preferably larger, fluid acquisition/distribution layer containing little or no hydrogel. This lower fluid storage layer is positioned in such a manner that at least about 75% of the hydrogel in the lower layer is found in the front two-thirds of the absorbent article and such that at least about 55% of the hydrogel in the lower layer is found in the front half of the absorbent article. Absorbent articles of this type make especially effective and efficient use of the hydrogel material and may also provide a diaper rash control benefit.Type: GrantFiled: August 11, 1986Date of Patent: June 16, 1987Assignee: The Procter & Gamble CompanyInventors: Paul T. Weisman, Dawn I. Houghton, Dale A. Gellert
