Chemical description: Fatty alcohol C12-C18 + 5 EO
CASR-NUMBER: 68213-23-0
Appearance: Clear to cloudy, colourless liquid

APPLICATIONS

DEHYDOL LT 5 shows the optimum detergency at 30 - 60 °C washing temperature.
Furthermore, DEHYDOL LT 5 is suitable for the manufacture of heavy-duty detergents for the household and institutional sector.
DEHYDOL LT 5 is suitable for the manufacture of special detergents for the household and institutional sector.

DEHYDOL LT 5 is also a very good raw material for the manufacture of liquid wool and light-duty detergents.
The balanced alkyl chain of the natural fatty used as well as the hydrophilic behaviour contribute to the fact that DEHYDOL LT 5 is a product with a broad range of application.

DEHYDOL LT 5 is a fatty alcohol that is a very good raw material for the manufacture of liquid wool and light-duty detergents.
Moreover, DEHYDOL LT 5 is nonionic surfactant.

DESCRIPTION

DEHYDOL LT 5 is clear to cloudy, colourless liquid.
Additionally, DEHYDOL LT 5 is nonionic surfactant.
DEHYDOL LT 5 is alkyl polyethylene glycol ethers made from a C12-C18-alcohol and ethylene oxide.

DEHYDOL LT 5 can be stored in sealed original containers below 40°C for at least 2 years.
The chemical formula of DEHYDOL LT 5 is RO(CH2CH2O)5H.

Dehydol LT 5 is a cloudy liquid at room temperature and tends to form sediment.
Dehydol LT 5 becomes clear liquid at 40 °C.

It is recommended the preparation of 10 – 25% stock solutions of Dehydol LT 5 if it is to be used in the form of very dilute solutions, or if it is to be added to other solutions.
This makes it very much easier to dilute Dehydol LT 5 solution later on.
Dehydol LT 5 can form fairly stiff gels at certain concentrations when water is added.

STORAGE

a) Dehydol LT 5 should be stored indoors in a dry place. Storage rooms must not be overheated (see flash point).

b) Dehydol LT 5 is hygroscopic due to its good solubility in water, with the result that it may absorb moisture very quickly.
Drums must be resealed each time they are opened.

c) The storage temperature should not be allowed to fall substantially below 20 °C.
The congealing point of Dehydol LT 5 also need to be taken into account.

d) Dehydol LT 5 is a cloudy liquid and tend to form sediment, it becomes clear liquid at 40 °C.

e) Liquid that has solidified or that shows signs of sedimentation should be heated to 50 – 70 °C and homogenized before it is processed.
Please mix sufficiently prior to use.

f) 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.

g) Dehydol LT 5 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.

The following materials can be used for tanks and drums of Dehydol LT 5:
a) AISI 321 stainless steel (X6CrNiTi1810)
b) AISI 316 Ti stainless steel (X6CrNiMoTi17122)

Dehydol LT 5 is stored properly and drums are kept tightly sealed, Dehydol LT 5 have a shelf life of at least two years in its original packaging.
