Stabilizing agents gelatine

Olsen patented simplified process for stabilizing and gelatinizing nitrocellulose powder and for producing it in spherical form, with or without deterrents, coatings, and other modifying agents. 

Carbodiimides have also been proposed as stabilizing agents for cinnamate ester based photo-polymers. " Also, adhesion of the gelatinous photographic materials to a poly(ethylene terephthalate) support is improved through the addition of carbodiimides. ... 

Each vial contains imiglucerase (212 units), mannitol (170 mg), sodium citrates (70 mg), trisodium citrate (52 mg), disodium hydrogen citrate (18 mg), polysorbate 80 (0.53 mg). Citric acid and/or sodium hydroxide may have been added at the time of manufacture to adjust pH. Haemaccel (cross-linked gelatin polypeptides) is used as a stabilizing agent. 

Protective colloids (gum arabic or gelatine) can be added as stabilizing agents. Au, Pt, Pd, and Hg react similarly to silver in an acid medium, but copper does not interfere. Anions that form sparingly soluble silver salts do interfere. 

Both the purity of the enzyme and the hydrophobicity or polarity of the solvent are important parameters for the stability of enzymes. Wehtje et al. [108] found an interesting process for stabilization of immobilized enzymes. They added stabilizing agents (polyethylene glycol, gelatin, casein, tryptone, peptone, or albumin) when immobilizing the enzyme on the support. 

A typical recipe for batch emulsion polymerization is shown in Table 13. A reaction time of 7—8 h at 30°C is requited for 95—98% conversion. A latex is produced with an average particle diameter of 100—150 nm. Other modifying ingredients may be present, eg, other colloidal protective agents such as gelatin or carboxymethylcellulose, initiator activators such as redox types, chelates, plasticizers, stabilizers, and chain-transfer agents. 

Thickeners and binders such as acacia, agar, starch, sodium alig-nate, gelatin, methyl cellulose, bentonite, and silica are used to improve product stability and enhance the convenience of the administration of a liquid formulation. Surface-active agents, colors, flavors and preservatives may also be used in the final formulation (Garcia et ah. Bioseparation Process Science, Blackwell Science, Malden, Mass., 1999, p. 374). 

It was known that some stabilizers act also as gelatinizers or colloiding agents...
