GENAPOL X 158 is a nonionic surfactant for the detergent industry.
Applications of GENAPOL X 158:
Owing to their excellent surface-active properties the GENAPOL X grades have numerous uses.
Having excellent wetting action, especially in the low-temperature range, and marked degreasing and emulsifying properties, they are suitable raw materials and mixture components for the manufacture of universal cleaners in every form.
Major fields of application are:
Cleaners for the technical sector,
Uses of GENAPOL X 158:
GENAPOL X 158 is used in emulsion polymerization of vinyl acetate, acrylate and styrene / acrylate dispersions to reduce coagulation and to improve electrolyte resistance and freeze/thaw stability.
GENAPOL X 158 is used either during or after polymerization.
Stability of GENAPOL X 158:
The GENAPOL X-grades are insensitive to water hardness constituents and largely resistant to the usual chemicals in normal application concentrations.
Like all polyglycol ether derivatives, the GENAPOL X grades have limited stability to oxidizing agents which evolve chlorine so that their use is restricted to application in dilute solutions.
The preparation of highly concentrated mixtures of oxidizing or reducing agents and polyglycol ether derivatives is not possible.
Miscibility of GENAPOL X 158:
As nonionic surfactants the GENAPOL X grades can be used together with other products regardless of their ionicity.
Solubility of GENAPOL X 158:
The solubility of GENAPOL X grades in water, like that of most nonionic surfactants, depends on their degree of ethoxilation.
Cloud point of GENAPOL X 158:
The cloud point of the GENAPOL X grades, like that of all polyglycol ether derivatives, is a reliable indicator of their degree of ethoxilation.
Surface-active properties of GENAPOL X 158:
The surface-active properties of the GENAPOL X grades, like their solubility, largely depend on the degree of ethoxilation.
Wetting effect of GENAPOL X 158:
The wetting effect increases with the degree of ethoxilation to attain an optimum in readily water-soluble GENAPOL X-080.
The wetting capacity of GENAPOL X 080 is particularly marked in the low-temperature range.
Surface tension of GENAPOL X 158:
The ability to lower the surface tension of water is also related to the degree of ethoxilation.
The most effective grades are GENAPOL X-060 and GENAPOL X-080.
The effect on the surface tension of water decreases as the degree of ethoxilation increases.
Cleaning properties of GENAPOL X 158:
The GENAPOL X grades are noted for their excellent cleaning properties.
Whereas GENAPOL X-060 has a very strong degreasing action and is preferred when greasebound contamination is to be removed, GENAPOL X-080 is mainly used to remove pigmented contamination.
Foaming of GENAPOL X 158:
The foaming capacity of GENAPOL X grades varies from moderate to slight according to the degree of ethoxilation.
GENAPOL X-020 has the least tendency to foam.
The foaming capacity slightly increases with increasing ethylene glycol content but does not equal that of anionic surface-active compounds.
Handling and Storage of GENAPOL X 158:
Below 10 °C GENAPOL X 158 forms a gel.
Storage of GENAPOL X 158:
GENAPOL X 158 can be stored at least to 2 years in original sealed containers at room temperature under the recommended conditions.
Protect from exposure to cold during transport and storage.
The properties of GENAPOL X 158 are reversibly altered by exposure to cold.
If GENAPOL X 158 becomes turbid, thickens or freezes through exposure to cold, thaw slowly at room temperature and afterwards stir briefly.
