Emulsifier

An emulsifier also known as a surfactant from surface active material or emulgent is a substance which stabilizes an emulsion. A wide variety of emulsifiers are used in pharmacy to prepare emulsions such as creams and lotions. Silicon Oil Emulsifier, Amino Oil Emulsifier, Paraffin Wax Emulsifier are name of some Emulsifier.

The manufacturers emulsify the lipid soluble propofol in mixture water, soy oil and egg lecithin. Whether an emulsion turns into a water-in-oil emulsion or an oil-in-water emulsion depends on the volume fraction of both phases and on the type of emulsifier. Generally, the Bancroft rule applies: emulsifiers and emulsifying particles tend to promote dispersion of the phase in which they do not dissolve very well; for example, proteins dissolve better in water than in oil and so tend to form oil-in-water emulsions.

Emulsifiers for amino silicon oil to produce water transparent micro emulsion. These water clear emulsions produce better finishing properties than milky white macro emulsions. Specially developed sequestering agent for polyester dyeing & printing. It takes care of Iron impurities under acidic condition at elevated temperature under these conditions; other conventional sequestering agents do not offer adequate protection. 

A new concentrated emulsifier recently introduced has demonstrated that just five gallons of emulsifier a day can provide equivalent or better electrical stability (ES) than conventional emulsifiers. An innovative development in surfactant technology makes this possible and changes almost everything we have come to expect from conventional oil mud emulsifiers. The new emulsifier not only gets results with lower treatment levels, but also helps provide filtration control. Fluids service representatives carefully monitor properties such as the electrical stability to gauge the health of the emulsion. As a rule, emulsifier products are added to provide stronger emulsions or accommodate influxes of water or formation solids.

Standard hydrocarbon-based usually adequate to obtain the desired stability, except in situations where there high level of silicones in the oil phase, silicone emulsifiers may be desirable.

Surfactants

A surfactant or surface active agent is a substance that, when dissolved in water, gives a product the ability to remove dirt from surfaces such as the human skin, textiles, and other solids.  Most adjuvant contains one or more chemical compounds known as surfactants. Surfactants have the physical characteristics of both oil and water. Surfactant molecules contain a water (hydrophilic) head and an oil (lipophilic) tail.
 
Surfactants, or surface-acting agents, are a broad category of adjuvant that facilitate and enhance the absorbing, emulsifying, dispersing, spreading, sticking, wetting or penetrating properties of pesticides. Surfactants are most often used with herbicides to help a pesticide spread over and penetrate the waxy cuticle of a leaf or to penetrate through the small hairs present on a leaf surface. Because of the high surface tension of water, spray mixture droplets can maintain their roundness and sit on the leaf hairs or waxy surface without much of the herbicide actually contacting the leaf.

Surfactant: Technical terms:

  • Surfactant enables the cleaning solution to fully wet the surface being cleaned so that dirt can be readily loosened and removed.
  • Surfactant cleans greasy, oily, particulate, protein, and carbohydrate-based stains.
  • Surfactant are instrumental in removing dirt and in keeping them emulsified, suspended, and dispersed so they don't settle back onto the surface being cleaned.

Each surfactant molecule has a hydrophilic (water-loving) head that is attracted to water molecules and a hydrophobic (water-hating) tail that repels water and simultaneously attaches itself to oil and grease in dirt. These opposing forces loosen the dirt and suspend it in the water. The mechanical agitation of the washing machine helps pull the dirt free.

Surfactants are one of the major components of cleaning products and can be regarded as the 'workhorses': they do the basic work of breaking up stains and keeping the dirt in the water solution to prevent re-deposition of the dirt onto the surface from which it has just been removed. Surfactants disperse dirt that normally does not dissolve in water.

Surfactants are used by a variety of industries as diverse as cosmetics and steel manufacture. They are employed as:

  • Antistatic Agents
  • Plasticisers Detergents
  • Scouring agents
  • Dispersants Solubilisers
  • Emulsifiers
  • Wetting Agents Leveling Agents

With the addition of surfactants, oil, which normally does not dissolve in water, becomes dispersible and can be removed with the wash water.

There are two types of surfactants based on their chemistry:

Non-ionic surfactants and the silicone compounds.

Non-ionic Surfactants

Non-ionic surfactants (NIS) are composed of alcohols and fatty acids, have no electrical charge and are compatible with most pesticides. Non-ionic surfactants are all-purpose and the most widely recommended.

Certain surfactants may be cationic (+ charge) or anionic (- charge) and are specialty adjuvant that are used in certain situations and with certain products. Anionic surfactants are mostly used with acids or salts. They are more specialized and used as dispersants and compatibility agents.

Silicone Compounds

Silicone-based surfactants, also known as organo silicones, are increasing in popularity due to their superior spreading ability. Some of these surfactants are a blend of Non-ionic Surfactants and silicone while others are entirely silicone.
The combination of a Non-ionic Surfactants and a silicone surfactant can increase absorption into a plant so that the time between application and rainfall can be shortened. This is known as rain fastness.

Surfactants can work in three different ways: roll-up, emulsification, and solubilization.

Roll-up mechanism

The surfactant lowers the oil/solution and fabric/solution interfacial tensions and in this way lifts the stain of the fabric.

Emulsification

The surfactant lowers the oil-solution interfacial tension and makes easy emulsification of the oily soils possible.

Solubilization

Through interaction with the micelles of a surfactant in a solvent (water), a substance spontaneously dissolves to form a stable and clear solution.
