DESCRIPTION:
Dehydol LT 6 is nonionic surfactants.
Dehydol LT 6 is alkyl polyethylene glycol ethers made from a C12-C18-alcohol and ethylene oxide.
Dehydol LT 6 is a cloudy liquid at room temperature and tends to form sediment.
Dehydol LT 6 becomes clear liquid at 40 °C.
A fatty alcohol that is a very good raw material for the manufacture of liquid wool and light-duty detergents.

STORAGE OF DEHYDOL LT 6:
Dehydol LT 6 should be stored indoors in a dry place.
Storage rooms must not be overheated (see flash point).
Dehydol LT 6 is hygroscopic due to its good solubility in water, with the result that Dehydol LT 6 may absorb moisture very quickly.
Drums must be resealed each time they are opened.
The storage temperature should not be allowed to fall substantially below 20 °C.
The congealing point of Dehydol LT 6 also need to be taken into account.
Dehydol LT 6 is a cloudy liquid and tends to form sediment, Dehydol LT 6 becomes a clear liquid at 40 °C.
Liquid that has solidified or that shows signs of sedimentation should be heated 50 – 70 °C and homogenized before it is processed.
Please mix sufficiently prior to use.
Drums that have solidified or that have begun to precipitate should be reconstituted by gentle heating, preferably in a heating cabinet.
The temperature must not be allowed to exceed 70 °C.
Please mix sufficiently prior to use.
This also applies if drums are heated by external electrical elements.
Internal electrical elements should not be used because of the localized anomalies in temperature that they cause.
Dehydol LT 6 must be blanketed with nitrogen if they are stored in heated tanks (at 50 – 60 °C) to prevent it from coming into contact with air.
Constant, gentle stirring helps to prevent it being discolored as a result of prolonged contact with
electrical elements or external heating coils.
SHELF LIFE OF DEHYDOL LT 6:
Provided Dehydol LT 6 is are stored properly and drums are kept tightly sealed, Dehydol LT 6 has a shelf life of at least 24 months in its original packaging.
