Genamin MDAH is an anionic wetting and dispersing agent.

CAS Registry Number: 12645-31-7
EINECS: 235-741-0
Molecular Formula: C8H18O.x(H3PO4)

Trade name:
HOSTAPHAT MDAH 

Use of Genamin MDAH:
Industry sector : Industrial Performance Chemicals
Type of use : Special emulsifier for pastes for fountain pen inks

Chemical characterization of Genamin MDAH:
Phosphoric acid mono-bis-(2-ethylhexyl)-ester

Alcohol phosphoric acid ester. 
Ideal dosage of Genamin MDAH (on pigments) is 10-40%. 

Genamin MDAH is used as a dispersing agent for organic pigments in inks. 
Genamin MDAH is approved for ecolabels and complies with the following regulations: environmental label (blue angel), EINECS, TSCA, DSL, AICS, CN, ECL, and METI.

Genamin MDAH is an anionic wetting and dispersing agent. 
Genamin MDAH is composed of alkyl phosphoric acid mono / diester, acid form. 
Genamin MDAH is used as wetting and dispersing agent for pigment dispersions and as a stabilizer for aqueous metallic pigment pastes.

Genamin MDAH increases the colour intensity in colour bases. 
For metal pigment pastes Genamin prevents the coagulation of the metal pigments and protects the metal particles from corrosion.

Storage and handling of Genamin MDAH:
Storage stability of Genamin MDAH is practically unlimited - no special precautions are necessary. 
Being corrosive to skin on prolonged contact, goggles and gloves should be worn when handling the undiluted products. 

Splashes of Genamin MDAH should be rinsed from the skin with a plenty of water. 
If splashes come into the eye, it should be rinsed with a plenty of water and a doctor should be consulted immediately.

Applications of Genamin MDAH:
Genamin MDAH has successfully been used for the flotation of heavy minerals from glass sands and for the flotation of carbonates (i.e. calcite) from silicates.
Other possible uses are the flotation of tungsten- and titanium minerals.

Genamin MDAH is fed either undiluted into the conditioning tank (this requires a pulp density of 60-65 % solids) or as an aqueous emulsion. 
Therefore, the product should be poured into water and stirred whilst adding caustic soda (NaOH). 

For neutralizing 1 g Genamin MDAH 3.8 g caustic soda (40 %) is required. 
The concentration of the aqueious emulsion should not exceed 5 %. 
In the case of carbonate flotation it may be advisable to use it together with fatty acids in various ratios.
