ALFOTERRA 123-8S 90 exhibits a unique extended surfactant structure allowing solubilization of oily materials in an aqueous medium by extending the interface. This chemical structure gives at the surfactant unique emulsification properties and ultra-low interfacial surface tensions (IFT).
ALFOTERRA 123-8S 90 improves oil recovery by cold wells (temperature lower than 60°C), improves the ability to emulsify oil/water and vice versa considering EACN range 12-16.
ALFOTERRA 123-8S 90 is supplied as emulsifier in EOR and several differentiated oil applications such as cleaning tanks, drilling cuts and borehole cleaning.
ALFOTERRA 123-8S 90 might be used alone or blended with other non-ionic surfactants as well as polymers.

Storage & Handling
- Storage and Handling
- ALFOTERRA 123-8S 90 must be preferably stored in stainless steel or fiber glass tanks. The ideal storage temperature is +10°C to +30°C. The product should be heated by glycol or hot water set to 45°C maximum temperature under gently stirring. Steam heating should be avoided as hot spots may degrade the product. For long-term storage, the material should be maintained at +20 to +30°C, possibly blanketed with nitrogen or other inert gas and gently mixed if needed.
- Vigorous mixing which causes air entrapment should be avoided.
- Contact with acids and/or treatment at temperature higher than 30°C for prolonged time could cause hydrolysis.
- ALFOTERRA 123-8S 90 is a viscous liquid at room temperature and it becomes not pourable at temperature lower than -30°C.
- Diluted water solution of ALFOTERRA 123-8S 90 can be easily prepared at room temperature by adding the product in water under stirring;
- Addition of water to ALFOTERRA 123-8S 90 has to be avoided because of the high viscosity of solutions at concentrations around 50% active.
- ALFOTERRA 123-8S 90 is not susceptible to microbial contamination. If the product is stored for several weeks it is recommended to carry out regular check of pH value.
