Alcohols, Dispex Ultra FA 4430 are non-ionic surfactants derived from the ethoxylation of fatty alcohols with carbon chain lengths ranging from 12 to 14 carbon atoms.
Dispex Ultra FA 4430's typically exhibit excellent emulsifying, wetting, and dispersing properties, making them valuable in various applications, including personal care products, detergents, and industrial formulations.
They are characterized by their hydrophilic-lipophilic balance (HLB) values, which influence their solubility and effectiveness in different environments.
Ethoxylated alcohols are generally biodegradable and have low toxicity, making them environmentally friendly options.
Additionally, they can enhance the stability of emulsions and improve the performance of cleaning products by reducing surface tension.
However, the specific properties, such as viscosity and cloud point, can vary based on the degree of ethoxylation and the presence of other ingredients in formulations.
Overall, these surfactants are versatile and widely used in both consumer and industrial applications due to their functional benefits.

C12-14 ethoxylated alcohols are a category of nonionic surfactants that are manufactured through the process of adding ethylene oxide to fatty alcohols, which in turn are derived from either natural or synthetic sources.
These substances are commonly utilized in various industries due to their unique properties.
They are known for their ability to reduce surface tension in liquids, which makes them effective in applications such as detergents, emulsifiers, and wetting agents.
Typically, these compounds manifest as clear, viscous liquids or pastes, which makes them easy to handle and incorporate into formulations.
The ethoxylation process not only enhances their solubility in water but also improves their compatibility with other ingredients, thus making them versatile components in many formulations.
Their nonionic nature means they do not ionize in solution, which contributes to their stability and effectiveness in a wide pH range.
This makes them particularly useful in products where harsh chemicals or extreme pH conditions are not desirable.
Dispex Ultra FA 4430 is aliphatic polyether with acidic groups.
Acts as a dispersing agent.
Offers benefits such as reduced grinding and dispersion time, increased pigment loading in the mill-base or pigment concentrate enabling to achieve VOC level below 250 g/l in highly filled solvent-based system and improved gloss, levelling and flow.
Dispex Ultra FA 4430 is used in hot melt, solvent-based, solvent-free, reactive, water based and radiation curing adhesives and in sealants.

Synthesis
KOH（1g） and dodecanol (24.8 g ) were heated to 85° C in the reactor, then vacuumed and filled with nitrogen for 2 to 3 times.
The mixtrue was heated to 120 ℃～130℃, and added with ethylene oxide (EO), propylene oxide (PO) or their mixture.
After the reaction is completed, the solution was neutralized with H2SO4(98%) and filtered to give Laureth-4.
