Formulating microemulsions (ME)

Anionic surfactants are required in an ME formulation to form a spontaneous emulsion. Due to the overall charge on an anionic emulsifier it provides additional electrostatic stabilisation.

Atlox™ 4838B

An oil-soluble anionic emulsifier for improved stability and blooming of formulations upon dilution. Commonly used as part of a triangle screen formulation approach.

Atplus 310 is a single product, emulsifier package. Its novel blend makes formulating an ME relatively easy and simple as blending ratios of the emulsifiers have already been predetermined. Microemulsions do not normally form in high electrolyte conditions. This is due to the disruption that electrolytes cause to steric stabilisation and the shielding effect to electrostatic repulsion between droplets. Atplus 310 however, is designed to overcome this problem and allows the formation of high electrolyte microemulsions.

Atplus™ 310

Highly efficient single surfactant emulsifier package for high electrolyte microemulsions. Allows the formation of a microemulsion of methylated seed oil (MSO) in ammonium sulphate (AMS), which is...

Our extensive range of phosphate esters gives the formulator a high degree of flexibility in their formulation design of microemulsions. When combined with other surfactants such as sarcosinates, they can provide stable microemulsion systems in very challenging conditions. As with the combination of non-ionic surfactants, it is important to consider pairing a phosphate ester with high solubility in your target aqueous system, along with a phosphate ester with high solubility in your target oil system.

Atlox™ AL-3382

Phosphate ester designed for improved emulsion stability in high electrolyte conditions. High cloud point of material gives strong performance as a ME stabiliser.
