Devices formed of or including biocompatible polyhydroxyalkanoates are provided with controlled degradation rates, preferably less than one year under physiological conditions. Preferred devices include sutures, suture fasteners, meniscus repair devices, rivets, tacks, staples, screws (including interference screws), bone plates and bone plating systems, surgical mesh, repair patches, slings, cardiovascular patches, orthopedic pins (including bone filling augmentation material), adhesion barriers, stents, guided tissue repair/regeneration devices, articular cartilage repair devices, nerve guides, tendon repair devices, atrial septal defect repair devices, pericardial patches, bulking and filling agents, vein valves, bone marrow scaffolds, meniscus regeneration devices, ligament and tendon grafts, ocular cell implants, spinal fusion cages, skin substitutes, dural substitutes, bone graft substitutes, bone dowels, wound dressings, and hemostats. The polyhydroxyalkanoates can contain additives, be formed of mixtures of monomers or include pendant groups or modifications in their backbones, or can be chemically modified, all to alter the degradation rates. The polyhydroxyalkanoate compositions also provide favorable mechanical properties, biocompatibility, and degradation times within desirable time frames under physiological conditions.

Medical devices and applications of polyhydroxyalkanoate polymers

A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM cleanup. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM cleanup. The lotion composition comprises a plastic or fluid polysiloxane emollient such as phenyl-functional polymethylsiloxanes, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the polysiloxane emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Provided herein are ether carboxylate builder compositions comprising a combination of tartrate monosuccinic acid (or salts thereof) and tartrate disuccinic acid (or salts thereof). Such mixtures can be prepared by reacting water-soluble, mixed maleic acid salts with mixed tartaric acid salts. Both components of the resulting ether carboxylate mixture act as sequestering agents and are useful as detergency builders. Detergent and laundry additive compositions incorporating these ether carboxylates can be prepared without use of detergent builder components containing phosphorus or nitrogen.

Environmentally degradable finely attenuated fibers produced by melt spinning a composition comprising destructurized starch, a biodegradable thermoplastic polymer, and a plasticizer are disclosed. The present invention is also directed to highly attenuated fibers containing thermoplastic polymer microfibrils which are formed within the starch matrix of the finely attenuated fiber. Nonwoven webs and disposable articles comprising the highly attenuated fibers are also disclosed.

Fibers comprising starch and biodegradable polymers

A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from 5 to about 15 % by weight. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an agent such as sorbitan stearates or N-cocoyl, N-methyl glucamide to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

Thermally bonded absorbent structures for catamenial products, in particular catamenial pads, that provide improved ability in acquiring, distributing and storing aqueous body fluids, especially menstrual fluids, as well as better fit and comfort for the user of the products. These structures comprise an optional thermally bonded secondary topsheet, a thermally bonded absorbent core having a relatively higher capillary suction primary fluid distribution layer, an optional but preferred relatively lower capillary suction secondary distribution layer, a storage layer having absorbent gelling material, and an optional fibrous "dusting" layer. These thermally bonded absorbent structures are particularly useful with catamenial pads having a primary fluid pervious topsheet selected from apertured formed film topsheets and high loft nonwoven topsheets.
