- Product Background
The BRIJ SERIES of surfactants are polyoxyethylene vegetable-based fatty ethers derived from lauryl, cetyl, stearyl and oleyl alcohols. BRIJ surfactants are stable to acids and alkalies beyond the pH range that ester type emulsifiers can withstand. Hence, the BRIJ SERIES are useful for emulsifying fats and oils in highly acidic or alkaline media. The series contains both hydrophilic and lipophilic products. Depending on the HLB, BRIJ surfactants can be used to form either oil-in-water (O/W) emulsions or water-in-oil (W/O) emulsions, solubilize oils and improve wetting. These products are widely used in personal care, fiber finish and HI&I cleaning, crop protection, paints and coatings, adhesives and other industrial applications.

- Applications
As ethoxylated alcohols, the Brijs are classified as ethers and possess certain behavioral characteristics inherent to these compounds. The presence of an ether linkage results in a greatly reduced to hydrolyse. These properties enable them to exhibit greater tolerance to more extreme levels of pH and to tolerate higher levels of electrolytes than ester-type surfactants. Brijs are therefore particularly recommended for use in extreme pH formulations.
Brijs behave synergistically and can therefore be formulated to greater effect when used in combination. This is particularly evident in the case of difficult to formulate emulsions such as clear gel microemulsions.
Detergency and cleaning
The selection of surfactants for detergent applications is usually carried out on the basis of chemical structure, e.g. relative sizes of the hydrophobic and hydrophilic groups. Optimum performance can be achieved with an alkyl chain length around C12- C15 and 4 - 10 moles of ethylene oxide. Brij L grades are particularly recommended for their rapid wetting and detergency. These properties make the Brij range highly useful in a variety of household detergent formulations.
Brijs are also effective emulsifiers and dispersing agents for many of the solvents used in liquid cleaners and degreasers. Brij 05 and Brij 010 are particularly useful for these applications.
The diverse properties of the Brij range makes these products suitable for all other types of cleaners such as liquid and solid detergent formulations, vehicle shampoo and wax cleaners, steel and glass cleaners. They can be utilized alone or in combination with anionic, cationic or other nonionic surfactants.Emulsification
When developing an emulsifying system it is often advantageous to use two or more surfactants. These will consist of one surfactant of relatively low HLB and another of relatively high HLB. A third component of intermediate HLB is sometimes incorporated. The average HLB of the mixture should approximate that required to emulsify the oily or dispersed phased.Solubility and solubilisation
The water solubility of members in each series increases with the degree of ethoxylation. Thus, the higher ethoxylates such as Brij 020, C20, CS20 and $20 are soluble in water and insoluble in mineral oil and other non-polar solvents. The lower ethoxylates such as Brij L4, O2 and S2 are soluble in mineral oil and other non-polar solvents, but are insoluble in water.
Product applications
• Hard surfaces
• Polishes
• Fabric Care
• Vehicle Cleaners
Hard surfaces
Hard surface cleaners are usually based on acidic or alkaline systems and therefore necessitate a surfactant which is chemically stable at extreme pH. Brijs are often preferred in these cases because of their stability and relatively low foaming properties. They are effective wetting agents and the performance of the cleaner can be optimized by selecting the Brij that is most suitable for the application.
Polishes
Brijs are excellent emulsifiers for wax / solvent combinations and can be used in many types of formulations ranging from aerosol fumiture polishes to car wash and wax polishes. Brij CS20, S20 and 020 are particularly effective emulsifiers for many natural and synthetic waxes.
Fabric care
Compatibility and chemical stability make the Brij range useful formulating aids in laundry liquid and powder detergents and conditioning agents. Utilized in the textile processing industry, the Brij range are effective at all temperature below cloud point and impart lubricity and antistatic properties to the finish. Textile oils and fiber finish agents can be emulsified by products in the Brij L, O and CS ranges.
Vehicle cleaning
Microemulsion degreasers and traffic film removers for automotive care benefit in performance from a combination of the Brij 0 series and Crodafos phosphate esters. As a blend, the two are able to produce superior gels with excellent clarity, doing so at a concentration that minimizes the level of surfactant required and hence, reducing irritation levels caused by excessive surfactant use. This is beneficial for harsh system
used in the consumer markets.
