Genamin S 080 is a wetting agent and can have other adjuvant functions.
Genamin S 080 is a surfactant for the chemical-technological industry.
This yellow to brown liquid is composed of stearylamine with 8 mol EO.
The "S" grade means the group is distinguished by Genamin S 080 saturated C16-C18 fatty amines.
Genamin grades can be combined with all types at nonionic and cationic surfactants.
The compatibility with anionic products must be checked for each case.
The Genamin grades are resistant to most chemicals at typical concentrations used.
They are insensitive to water hardness.
Their specific surface active properties make them valuable bases and additives for the chemical technical industry.
They can be used to manufacture textile auxiliaries (e.g. products for dyeing) mineral oil additives, crop protection products and pesticides, raw materials for cosmetics and adhesives.
Genamin S 080 is a wetting agent and can have other adjuvant functions.
Hydroxyethylated fatty amines are manufactured under the brand name Genamin.
They are a small class of surfactants made by reacting primary fatty amines with ethylene oxide.
Oil-in-water emulsifiers, detergents, foam surfactants for the following products:
Softeners for fabrics with a bactericidal effect;

The Genamin grades are resistant to most chemicals at typical concentrations used and insensitive to water hardness.
When preparing completely homogeneous aqueous solutions of ethoxylated amines "Genamin", Genamin S 080 is preferable to carry out the dissolution process at temperatures of 50-60°C.
This recommendation is due to the fact that in a certain range of surfactant concentrations (usually between 70 and 40% active substance), gel-like hydrates may appear, which dissolve slowly in cold water.
Gel formation can also be eliminated by the addition of solubilizers such as ethyl alcohol, isopropyl alcohol, ethylene glycol, propylene glycol, ethylene glycol and propylene glycol ethers, alkyl polyglycosides, sodium cumene sulfonate, etc.
These substances are also suitable when ethoxylated amines form cloudy solutions (emulsions) due to low HLB, limited solubility in concentrated solutions and in the presence of large amounts of electrolytes.
The solubility of ethoxylated amines always increases with their degree of ethoxylation.
Ethoxylated products with 2-5 moles of ethylene oxide per molecule form dispersions at room temperature.
Medium and highly ethoxylated products dissolve with the formation of transparent solutions.
Mixing low ethoxylated amines with higher ethoxylated amines always increases the solubility of the former in aqueous solutions.
With the same degree of ethoxylation, the more soluble products are amines with a shorter and less saturated hydrocarbon chain.
The solubilizing and wetting ability of ethoxylated amines increases with an increase in molecular weight or with an increase in their concentration in solution.
The maximum possible foaming ability is observed in ethoxylated cocoylamines and decreases with the growth of the hydrocarbon chain.
Depending on the HLB value, the degree of ethoxylation and the type of hydrocarbon radical, ethoxylated fatty amines "Genamin" can be grouped into the following application groups.
Crop protection
Physiochemical properties of Genamin S 080:
Ethoxylated amines "Genamin" are transparent viscous liquids.
Depending on the characteristics of the production technology and the quality of the feedstock, their color can vary from light yellow (almost colorless) to brown.
A typical amine number ranges from 44 to 216 mg KOH/g of substance.
The maximum water content is 1.0-0.5%.
The concentration of primary and secondary amines is less than 1-2%.
The solubility of ethoxylated amines in water depends on the hydrophilic-lipophilic balance (HLB) of the product.
Products with an HLB value ≥ 9 are highly soluble in water, ethylene glycol, acetone, chloroform and ethanol; at values 5 ≤ HLB ≤ 9, ethoxylated amines form dispersions with water, and transparent solutions with mineral oils.
Aqueous solutions of ethoxylates have an alkaline pH = 9-11.
Ethoxylated fatty amines, depending on the conditions, exhibit the characteristics of non-ionic or cationic surfactants.
In alkaline media, they acquire non-ionic properties similar to those of ethoxylated alcohols.
The presence of a polyester chain in the amine molecule gives them excellent emulsifying, dispersing, wetting and detergent properties.
Due to the formation of hydrogen bonds between water and etheric oxygen atoms, amines acquire the properties to dissolve in water, including those containing electrolytes.
The degree of hydration of the polyester chain decreases with increasing temperature, leading to cloudiness of the solution, indicating the loss of the hydration shell by the surfactant molecule with a corresponding decrease in solubility.
Highly ethoxylated amines may not have a cloud point.
In such cases, Genamin S 080 appearance is caused by the addition of inorganic electrolytes to the nonionic surfactant solution: sodium chloride, sodium sulfate, potassium chloride, etc., which is explained by the effect of salting out.
There is a relationship between the cloud point of an ethoxylated amine and the hydrophilic-lipophilic balance value.
In the HLB system, nonionic surfactants are classified on a scale of 0 to 20.
Ideally, an HLB surfactant is defined as the ratio of the molecular weight of the hydrophilic portion of the surfactant molecule (Mm) to the total molecular weight (M) times the number 20.
HLB = 20´Mm/M.
The presence of a nitrogen atom in the molecule of ethoxylated amines gives these compounds important advantages in properties and, therefore, in application over ethoxylated alcohols.
In acidic environments, at pH < 6.0, ethoxylated amines are protonated and acquire additional anticorrosive, antistatic, bactericidal, rheological, and other properties of cationic surfactants.
Separately, Genamin S 080 should be noted that ethoxylated amines are highly resistant to decomposition in strongly acidic, strongly alkaline, and oxidizing media.
Handling and storage of Genamin S 080:
Ethoxylated amines are transported in containers made of steel and fiberglass reinforced polyester.
To prevent decomposition and color deterioration, Genamin S 080 is recommended to store the products at a temperature not exceeding 50°C.
In the case of freezing and subsequent thawing, ethoxylated amines do not lose their consumer properties.
Safety of Genamin S 080:
Oxyethylated amines are low toxic products.
The oral lethal dose (LD50) for animals is 1.5-2.5 g/kg.
With prolonged exposure, ethoxylated amines can penetrate intact human and animal skin, causing eczema.
If Genamin S 080 gets into the eyes, Genamin S 080 irritates the mucous membrane of the eyes.
The maximum allowable concentration (MAC) in the waters of cultural and domestic and fisheries purposes is less than 5 mg/l.
