APPLICATION

DEV INTERNATIONAL surfactants are used by a variety of industries as diverse as cosmetics and steel manufacture. They are employed as:
Antistatic Agents
Plasticizers
Detergents
Scouring agents
Dispersants
Solubilizers
Emulsifiers
Wetting Agents
Leveling Agents
     
DETERGENTS AND CLEANERS
Hard surface cleaners are usually on acidic or alkaline systems and therefore necessitate a surfactant which is chemically stable at extreme pH. DEV INTERNATIONAL are often preferred in these cases because of their stability and relatively low foaming properties. High wetting and detergency are imparted to the product. The highest solubility, wetting and detergency properties are found in the DEV INTERNATIONAL TDA range, making them suitable surfactants for detergent and cleaner formulations.

DEV INTERNATIONAL are effective emulsifiers and dispersing agents for many of the solvents used in liquid cleaners and degreasers. DEV INTERNATIONAL OCA5 is most effective.

The diverse properties of DEV INTERNATIONAL suggest their use in many other cleaners, such as liquid detergents, metal cleaners, car. Washing compounds, dairy and glass cleaners. They can be employed alone or in conjunction with anionic; cationic or other non-ionic surfactants.

Nonionic surfactants can deactivates certain bactericides and DEV INTERNATIONAL should not be employed in germicidal cleaners based on phenolics such as PCMX or DCMX.

DETERGENTS INTERMEDIATES
Polyethoxlated fatty alcohols are used as intermediates in the manufacture of other surfactants eg. alkyl ether sulphates - a group of high foaming detergents used by many industries.

They are also the precursors of alkyl ether phosphates, a versatile class of anionic detergents, wetting and emulsifying agents.

METAL WORKING COMPOUNDS
DEV INTERNATIONAL OCA3 and OCA5 are effective emulsifiers for oil based and EP additives used in rolling oils and cutting fluids.

Metal pickling baths require surfactants of high wetting ability and DEV INTERNATIONAL TDA10 or TDA15 may be employed.

The 5 molar adducts of the DEV INTERNATIONAL range are useful wetting agents for pressing lubricants.

Good surface wetting is also important in maximizing the performance of metal grinding fluids and members of the DEV INTERNATIONAL TDA range are suitable. Improved performance here can be achieved by combining DEV INTERNATIONAL TDA with the triethanolamine salt or tridecyl ester phosphates.

Combinations of DEV INTERNATIONAL and alkyl ether phosphates, produce excellent, non-corrosive emulsifiers and confer improved EP properties to metal working fluids.

TEXTILE PROCESSING AIDS
DEV INTERNATIONAL have many applications in the processing of textile; they are used as lubricants, and as emulsifying, antistatic, scouring, wetting, dye leveling agents and lime soap dispersants.

DEV INTERNATIONAL are effective at all temperatures their cloud point, through maximum wetting is observed in conditions just below this critical temperature.

The more water soluble members of the range are useful detergents, wetting agents and dye leveling agents in both acidic and alkaline solutions and in environments where ionics are unsuitable.
 
Textile oils and fiber lubricants can be emulsified by products within the DEV INTERNATIONAL LA, OCA and CS series. They may also impart lubricity and antistatic properties to the finish.

PAPER PROCESSING AIDS
Absorbency and rewetting characteristics of paper toweling can be improved by the addition of a suitable DEV INTERNATIONAL during processing.

DUST CONTROL
The higher molar adducts of the DEV INTERNATIONAL TDA range aid the wetting down of dust in mines, quarries, mills and chimneys.

ADHESIVES
Animal glues are improved by the increased wetting properties by DEV INTERNATIONAL TDA10 GUAR GUM : CS-23 IS BEST SOFTENER FOR GUAR GUM

POLYMERS AND POLYMERISATION
The 20 molar ethoxylates of cetostearyl, oleyl cetyl and tridecyl alcohol’s are suitable surfactants for the emulsion polymerisation of vinyl resins. These DEV INTERNATIONAL also wet and effectively stabilise rubber latex.

POLISHES
DEV INTERNATIONAL are excellent emulsifiers for wax/solvent combinations and can be used in many types of polish formulations, including dry brites. DEV INTERNATIONAL CSA15, CSA20, OCA15 and OCA20 are particularly effective emulsifiers for many natural and synthetic waxes.

AGRICULTURE
DEV INTERNATIONAL used alone or in conjunction with anionic, cationic or other nonionic surfactants, are suitable emulsifiers and wetting agents for herbicides and pesticides etc. The choice of surfactant depends to a large extent on the solvent carrier and the active compound to be emulsified.

COSMETICS AND PHARMACEUTICALS
The DEV INTERNATIONAL CSA and OCA and LA series are general purpose emulsifying agents and are used extensively in cosmetic and pharmaceutical emulsion systems. Self-emulsifying wax bases can be produced by combining SHREE VALLABH CSA20 or DEV INTERNATIONAL CSA15 with cetostearyl alcohol.

Note: Above DEV INTERNATIONAL Range are the running products. We can produce higher moles on customer specific demand and specifications can be altered as per customer requirement.
