Degradability, enhanced

It is necessary to evaluate the injection homogeneity of a carbon source (cometabolite) for microbial degradation enhancement. It is injected electro-osmotically at 4 cm/day at 100 ppm with a homogeneous first-order rate constant for microbial degradation k = 0.1 day-1 (a 1-week half-life approx). AL = 1.00 cm, to obtain the steady-state concentration profile ofan additive to apenetration depth of 1 m. (Gale)...

In this chapter, we summarize the general approaches that have been used to successfully achieve the formulation goals for oral delivery minimize enzymatic degradation enhance intestinal absorption maximize blood level reproducibility deliver drug through the gut wall and produce a palatable and acceptable dosage form. Then insulin will be used as an example to show how oral bioavailability has been achieved through chemical modification.

The reduction of degradation enhancement due to orientation is better seen when samples are stretched and then the time to fail, under UV radiation, is recorded. The results are shown in Fig. 6 where one should notice the break in scale for the reference (non-oxldlzed) sample. There is a drastic decrease in failure time (F.T.) for low draw ratios 1 < X < 1.7. This can be attributed to stored elastic energy which makes the chemical bonds more reactive toward UV, even at low stress levels. As X increases and the polymer structure becomes more and more oriented, F.T. Increases steeply before reaching a plateau once the orientation process is more or less completed. If we consider that photooxidation is oxygen diffusion controlled (1-5), the orientation effect is to decrease such diffusion by making the structure much more compact so that the degradation will be reduced. 

To determine the effect of the particle size on the biodegradation of Dynasan 114 SLN, stabilized with sodium cholate, a degradation-enhancing surfactant and poloxamer 407 (a surfactant that hinders the enzymatic biodegradation [11]) were used to produce SLN of different sizes (Table 6.2). Sodium cholate-stabihzed SLN are in the size range of 182 to 304 run and do not show any differences in their ) 2005 by CRC Press LLC...

The incorporation of UV stabilizer is necessary for protection against UV degradation. Enhanced UV light stability can affect the color stability and the mechanical properties of plastics. UV stabilizers protect PE from damage by sunlight in outdoor environments. Similarly, carbon black in PE mulch film protects and blocks the penetration of radiation.
