Tween 80 or Polysorbate 80 under name Alkamuls PSMO, original from Solvay is a nonionic surfactant and emulsifier often used in foods and cosmetics. This synthetic compound is a viscous, water-soluble yellow liquid.

The full chemical names for polysorbate 80 are:
  • Polyoxyethylene (20) sorbitan monooleate
  • (x)-sorbitan mono-9-octadecenoate poly(oxy-1,2-ethanediyl)


Food use

Polysorbate 80 is used as an emulsifier in foods.
For example, in ice cream, polysorbate is added up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting.[4] Adding this substance prevents milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.

Health and beauty use

Polysorbate 80 is also used as a surfactant in soaps and cosmetics, or a solubilizer such as in a mouthwash. The cosmetic grade of polysorbate 80 may have more impurities than the food grade.

Medical use

Polysorbate 80 is an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the manufacture of the popular antiarrhythmic amiodarone. It is also used as an excipient in some European and Canadian influenza vaccines.[7] Influenza vaccines contain 25 ╬╝g of polysorbate 80 per dose.[7] It is also used in the culture of Mycobacterium tuberculosis in Middlebrook 7H9 broth. It is also used as an emulsifier in the estrogen-regulating drug Estrasorb.

Laboratory use

Some mycobacteria contain a type of lipase (enzyme that breaks up lipid molecules). When added to a mixture of polysorbate 80 and phenol red, they cause the solution to change colour, so this is used as a test to identify the phenotypeof a strain or isolate.

Potassium hydroxide 48 % solution, 90 % flake

Component in the production of potassium carbonate (K2CO3), rubber, soap, pharmaceuticals and food.

TRADE NAME : Caustic Potash Solution



KOH            % w/w     40-48.0 min.
K2CO3         % w/w    0.2 max.
KCI              % w/w    0.01 max.
Fe2O3          % w/w    0.001 max.


Caustic Potash solution is a raw material which is utilised in the soap manufacture, bleaching, manufacture of potassium carbonate and tetrapotassium pyrophosphate, electrolyte in alkaline storage batteries and some fuel cells, absorbent for carbon dioxide and hydrogen sulfide, dyestuffs, liquid fertilizers, food additive, herbicides, electroplating, mercerizing, paint removers.

KOH has mainly industrial uses. On a global level the main uses are (Occidental Chem. Corp., 2000):

  • Potassium carbonate: 26 % 
  • Chemical manufacturing: 16 % 
  • Potassium chemicals: 12 % 
  • Fertilizers: 11 %
  • Phosphates: 9 % 
  • Detergents: 8 % 
  • Agricultural chemicals: 7 % 
  • Alkaline batteries: 6 %
  • All other: 5 %.

More than 95% of the KOH production is for non dispersive use, and is consumed by the industry, mainly by large enterprises. KOH is used in these applications as an intermediate and do not leave the plant where it is used. In these applications, KOH is consumed in a reaction and is no more present in the product that goes to the market. KOH is still present in the alkaline batteries, but here this substance is strictly confined in the battery screening and doesn’t come in contact with the consumer.

Less than 5% of the KOH production is for wide dispersive use and enters in the composition of consumer products (eventually to be consumed in small enterprises like garages or farms): paint and varnish removers (ICCA-HPV KOH Consortium, 2001), drain cleaners (Howell, 1991; Leape et al., 1971), degreasing agents (Swanson et al., 1995) and dairy pipeline cleaners (Edmonson, 1987).

Potassium hydroxide is a food additive, listed as E525 in Annex 1 of Directive 95/2/EU. This means that KOH is a general food additive to be used following the “quantum satis” principle: as much as necessary according to GMP (European Union, 1995).


Store in a cool, dry, well ventilated area. Store away from incompatible
materials such as strong acids, mitroaromatic, nitroparaffinic
or organohalogen compounds.

Lauric acid or systematically, dodecanoic acid, is a saturated fatty acidwith a 12-carbon atom chain, thus falling into the medium chain fatty acids, is a white, powdery solid with a faint odor of bay oil or soap.

Like many other fatty acids, lauric acid is inexpensive, has a long shelf-life, and is non-toxic and safe to handle. It is mainly used for the production of soaps and cosmetics. For these purposes, lauric acid is neutralized with sodium hydroxide to give sodium laurate, which is a soap. Most commonly, sodium laurate is obtained by saponification of various oils, such as coconut oil. These precursors give mixtures of sodium laurate and other soaps.

In the laboratory, Lauric acid is often used to investigate the molar massof an unknown substance via the freezing-point depression. Lauric acid is convenient because its melting point when pure is relatively high (43.8 °C). Its cryoscopic constant is 3.9 °C·kg/mol. By melting lauric acid with the unknown substance, allowing it to cool, and recording the temperature at which the mixture freezes, the molar mass of the unknown compound may be determined

In vitro experiments have suggested that some fatty acids including lauric acid could be a useful component in a treatment for acne, but no clinical trials have yet been conducted to evaluate this potential benefit in humans.
Lauric acid increases total serum cholesterol more than many other fatty acids. But most of the increase is attributable to an increase in high-density lipoprotein (HDL) (the "good" blood cholesterol). As a result, lauric acid has been characterized as having "a more favorable effect on total HDL cholesterol than any other fatty acid [examined], either saturated or unsaturated". In general, a lower total/HDL serum cholesterol ratio correlates with a decrease in atherosclerotic risk. Nonetheless, an extensive meta-analysis on foods affecting the total/LDL serum cholesterol ratio found in 2003 that the net effects of lauric acid on coronary artery disease outcomes remained uncertain.

EDTA as Chelating Agent

Chelation is a chemical combination with a metal in complexes in which the metal is part of a ring. Organic ligand is called chelator or chelating agent, the chelate is a metal complex. The larger number of ring closures to a metal atom is the more stable the compound. 

This phenomenon is called the chelate effect; it is generally attributed to an increase in the thermodynamic quantity called entropy that accompanies chelation. The stability of a chelate is also related to the number of atoms in the chelate ring. 

Monodentate ligands which have one coordinating atom like H2O or NH3 are easily broken apart by other chemical processes, whereas polydentate chelators, donating multiple binds to metal ion, provide more stable complexes. Chlorophyll, green plant pigment, is a chelate that consists of a central magnesium atom joined with four complex chelating agent (pyrrole ring). The molecular structure of the chlorophyll is similar to that of the heme bound to proteins to form hemoglobin, except that the latter contains iron(II) ion in the center of the porphyrin. Heme is an iron chelate. 

 Chelation is applied in metal complex chemistry, organic and inorganic chemistry, biochemistry, and environment protection. It is used in chemotherapeutic treatments for metal poisoning. Chelating agents offers a wide range of sequestrants to control metal ions in aqueous systems. By forming stable water soluble complexes with multivalent metal ions, chelating agents prevent undesired interaction by blocking normal reactivity of metal ions. EDTA (ethylenediamine tetraacetate) is a good example of common chelating agent which have nitrogen atoms and short chain carboxylic groups. The sodium salt of EDTA is used as an antidote for metal poisoning, an anticoagulant, and an ingredient in a variety of detergents. 

 Chelating agents are important in the field of soap, detergents, textile dyeing, water softening, metal finishing and plating, pulp and paper, enzyme deactivation, photo chemistry, and bacteriocides.
