Stress cracking in poly(alkylene terephthalate) articles of manufacture is inhibited by applying to the article a stress crack inhibitor which contains an amine having at least 6 carbon atoms. In a preferred embodiment, the stress crack inhibitor is applied to the article in the form of an aqueous fatty acid-based lubricant.

Composition for inhibiting stress cracks in plastic articles and methods

Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a hardness sequestering agent, such as an alkali metal complex phosphate sequestrant. The resulting mixture is, then, pelletized on a chill belt. A source of solid active chlorine pellets is combined with the pelletized mixture. Chlorine degradation is essentially eliminated by combining the alkaline material pellets with the pelletized chlorine source.

Detergent pellet composition and process therefor

Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a heat-alkaline sensitive material, such as, an alkali metal complex phosphate sequestrant and/or an active-chlorine source. The resulting mixture is, then, pelletized on a chill belt. Because of the short contact time between the molten alkaline material and the sequestrant and the rapid solidification, reversion of the sequestrant, particularly, a phosphate sequestrant, is substantially reduced.
