Stabilities As it is the case for all enzyme products the effectiveness of BeizolHT -100 is impaired a lot by heavy metal iol)s and salts thereof,oxidizing agents, alkalis (> pH 9.0) and acids pH 4.0). A number oftensides, espeically the ones with an anionic reaction may impair theenzymatic starch decomposition.

The product is to a limited extent sensitive to frost; changes occurringat low temperatures are reversible on warming and after thoroughstirring.

Shelf life Under adequate storage conditions, i.e. in a cool place, the productcan be stored for about 12 months.

Properties,.--

Beisol HT -100 is an enzymatic product which decomposes starch not only at temperatures normally used fordesizing processes (65 -70C) but also at boiling temperature. Due to this heat stability the application ofBeisol HT -100 is not limited to short time processes (e.g. Pad-steam process with 1 min. steaming time,) but it isalso possible to apply it on ranges which need a longer reaction time (e.g. combi-steamer, jigger).

Heavy metal ions impair the enzymatic decomposition of the amylases very much. Therefore it is of advantageto add to the desizing liquor a sequestering agent, e.g. Heptol ESW, with a high heavy metal sequesteringcapacity. Alkaline earth ions have a stabilizing effect on the enzymes, thus we recommend to use hard water forthe desizing process.

If the decomposition of the starch size is insufficient, e.g. after a one-step pretreatment process, it can be postdesized in the washing machine with the addition of Beisol HT -100.

To assess the desizing effect, a thorough washing is necessary. A short washing in cold water is not sufficient.To obtain perfectly desized goods, a hot, possibly alkaline wash off is advisable.
