Proper Storage Conditions for Laundry
Detergents:
Laundry
detergents are generally manufactured in three physical states, solid, paste
and liquid. The liquid formulations are produced in different viscosity
depending on the application. Below we will discuss the proper storage
conditions of our detergents, based on their chemical composition.
Powder detergent:
Moisture:
It
must be stored in a dry environment, since moisture will make the product cake
(harden). When the product is hard, it will not dissolve as easy, it will plug
the dispensers of the laundry machines and chemical reactions will make the
product deteriorate.
Our
powder detergent contains sodium percarbonate to help the stain removal
process. This chemical is not stable when moist and will decompose overtime in
a moist environment.
Temperature:
Low
temperatures do not affect the powder detergent much, but as the product
contains a minute amount of moisture and a liquid detergent absorbed into the
other ingredient, exposure to very low temperatures for a period of time may
result in hardening of the product. This process will not affect the
functionality of the detergent.
High
temperatures may produce the product to lose oxygen, which will render it less
effective to remove stains
Recommendations: Store the product in a dry place at room temperature
(or in the range of 50F to 80F)
Liquid detergents:
Liquid
detergent formulations are very sensitive to heat. Moisture is not a concern in
this case. There are several effects that the temperature will have on the
liquid formulations. To understand these effects is necessary to know that
liquid detergents are not true solutions, the products are emulsified, in the
form of small micelles or coupled with each other by the use of hydrotropes.
In
addition to these issues in some cases it is preferred to thicken the detergent
systems for consumer appeal. Thickening is achieved by the use of salts or
carboses (or similar products).
Without
getting in-dept in the subject it is important to mention that in laundry
detergent formulations usually a mixture of anionic and non-ionic detergents
are used to achieve better cleaning. These detergents separate from the system
over or under a temperature called cloud point.
Exposure
of liquid detergents to very low
temperature produces freezing, several cycles of freezing and thawing will
destabilize the system producing separation of the components, precipitation or
loss of viscosity.
Exposure
to high temperatures will produce
similar effects, loss of viscosity and separation of the components and
possible precipitation.
Liquid
detergents are also more prone to microbial contamination of left open than
powder detergents.
Recommendations: Store the product in a dry place at room temperature
(or in the range of 50F to 80F)
