Personal Care Products. Within the broad definition of synthetic detergents, a variety of cleansing products are made for personal care. These include such products as cleansing bars, shampoos, bubble-bath products, cosmetic cleansers, and tooth pastes. Formulations of these products vary widely, depending upon their intended use. 

The most common derivative, N-methyl cocoyl taurine has limited solubility and is commercially available as a 30% paste. Formulators should be aware that the figure is typically a solid content, with the surfactant content being 25%, the balance of solids being mainly salt. 

These blends can take a number of different forms. The added resin may be reacted with the epoxy resin, or it may be included as an unreacted modifier. The modifier may be blended into a continuous phase with the epoxy resin (epoxy alloys) or precipitated out as a discrete phase within the epoxy resin matrix (as is generally done in the case of toughening modifiers). Epoxy hybrid adhesives are often used as film (supported and unsupported) or tape because of the ease with which formulated systems can be dissolved into solvent and applied to a carrier or deposited as a freestanding film. Some systems, notably epoxyurethanes and epoxy-poly sulfides, can be employed as a liquid or paste formulation because of the low-viscosity characteristics of the components. 

The dextranomer is supplied in beads of 100-300 pm diameter containing poloxamer 187, polyethylene glycol 300, and some water. A paste formulation is also available which is the dextranomer in polyethylene glycol 600 (PEG 600). The beads are offered as a discrete particle or enclosed in a low adherence pouch for insertion into a cavity wound. One company (Pfizer) offers a polymeric net which can be placed into a cavity wound before the addition of either granules or paste and facilitates removal and also a vapor permeable film which is superimposed on the dextranomer dressing to control evaporation and retard drying in a low exudating wound. 

Dextranomer has a pore size that produces an exclusion limit of 1000-8000 Da, which precludes the sorption of viruses and bacteria. Micro-organisms are removed from the wound by the capillary action between the beads, a function that is absent from the paste formulation, which however demonstrates a marked increase in absorbing capacity for malodorous elements and pain producing compounds released during the inflammatory response. 

A paste formulation of omeprazole is approved for use in horses. The bioavailability of the omeprazole is lower from the paste formulation an from the enteric-coated granules. More omeprazole in the paste was absorbed when administered to horses that had feed withheld than when given to horses that were fed (Daurio et al 1999). In humans, approximately 80% of omeprazole and pantoprazole are excreted in urine, with the remainder excreted in feces. Lansoprazole is primarily excreted in feces (up to 70%), indicating substantial hepatic metabolism and biliary excretion. 

In another report, the paste formulation of omeprazole approved for equine use markedly and equivalently suppressed gastric acid secretion and increased gastric fluid pH at p.o. dosages of 4.0 and 5.0mg/kg once daily (Daurio et al 1999). Data were collected after the fifth, tenth and fifteenth consecutive daily dosages acid output (H" as j.mol/15min per kg) was 99% suppressed when measured 8 h after the fifth dose, 95% when measured 16 h after the tenth dose and 90% when... 

Ivermectin, an endectocide, has activity against endoparasites (gastrointestinal roundworms and lungworms) and ectoparasites (mites and bots) of horses. The oral paste formulation of ivermectin (200 pg/kg) provides clinical... 

The storage stability of the components of composite formulations is mainly limited by the poor shelf-life of the BP ingredient ( ). Paste formulations, containing BP, but free of accelerator prematurely harden when stored at 60°C. Formulations using powder-liquid constituents are more stable at these elevated temperatures. After extended storage at room temperature for two years, composite mixes showed delayed setting and decreased mechanical properties in the cured material. The purity of the BP and the amine selected greatly influences parameters such as reaction rate, color stability and biocompatibility (18).
