Chemical: 3,6,9,12-Tetraoxatetradecane-1,14-diol

Chemical: Amylopectin, phosphate, 2-hydroxypropyl ether

3,6,9,12-Tetraoxatetradecane-1,14-diol is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of 3,6,9,12-Tetraoxatetradecane-1,14-diol are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

FRI - indicates a polymeric substance containing no free-radical initiator in its Inventory name but is considered to cover the designated polymer made with any free-radical initiator regardless of the amount used.

Hazards Summary · 1 件

Causes liver and male reproductive effects in 26-week intermittent oral studies of rats; [RTECS] Ethylene glycols: Category members demonstrate decreasing potential for systemic, reproductive, and developmental toxicity as the molecular weight increases; low dermal bioavailability; no evidence of skin sensitization in humans or guinea pigs; some evidence of mutagenicity; and no evidence of carcinogenicity. Pentaethylene glycol has the highest molecular weight in the category. The lowest molecular weight members produce renal toxicity by repeated oral exposure and developmental toxicity when rapidly ingested (bolus). These effects are not expected to occur with pentaethylene glycol; [OECD SIDS - Ethylene Glycols Category] A strong eye irritant; [Alfa Aesar MSDS]

毒性情報

Adverse EffectsOccupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

調製方法

Hydroxypropyl starch is produced industrially from natural starch, using propylene oxide as the modifying reagent in the presence of alkali, adding hydroxypropyl (CH(OH)CH2CH3) groups at the OH positions by an ether linkage.
