Spak AY-50 is specially recommended in formulations containing Sodium Sulfate. The commonly used surfactant of the same family e.g. Sodium Dioctyl Sulphosuccinate exhibits poor performance in presence of sodium sulfate. For example, 0.02% Spak AY-50 will reduce surface tension of 15% sodium sulfate solution to 26 dyne/cm where as sodium dioctyl sulphosuccinate will be salted out under these conditions. Similarly Spak AY-50 shows better tolerance to Ca ions than Sodium Dioctyl Sulphosuccinate.

Spak 61 is blend of an antifoamer and a defoamer. By antifoam we mean a product that prevents foam forming/stabilizing tendency and by defoamer we mean a product that kills the foam already formed. Spak 61 is a specially formulated product for Hemi-Dihydrate process operating at higher temperatures. It is better suited for higher temperature at 95-100°C. Spak 61 is equally useful in Dihydrate process.

SPAK HCO 40 is a vegetable-derived, ethoxylated (40) nonionic surfactant. It is suitable for a wide variety of applications providing emulsifying and solubilizing functionality. Hydrogenation of the castor oil results in greater oxidative stability with superior color and reduced odor.

SPAK DD-40 (AL) (EM) is a Polyol fatty acid ester. SPAK DD-40 (AL) (EM) acts as a defoamer & antifoamer i.e. it kills the foam formed and also reduces foam formation tendency in the system. SPAK DD-40 (AL) (EM) very well suits the fermentation system and has no adverse effect on yeast vitality and cell count (even at 1000 ppm in the fermentation system). This plays an important role in Alfa Laval process since the yeast is re-cycled in the process. The Polyol fatty acid ester has a high molecular weight and will not distill off and contaminate the end product. Foam can be a disaster in fermenters because it frequently results in loss of production. In a biotechnology system the conditions for foam production are always potentially present. Many organisms generate proteins, which are released into the surrounding medium. The proteins and the CO2 liberated generate foam in the fermentation system. SPAK offers a specially developed product SPAK DD-40 (AL) (EM) has a performance of antifoam and defoamer to suppress this foam.

IZA-90 is based on 1:1 molar reaction of selected coco chain fatty acid/ester with dietanolamine. It contains low concentration of unreacted diethanolamine and practically no fatty acid soap. It has a high percentage of amide and is predominantly nonionic in character. Thus due to its high amide content and purity it is classified as a “Superamide” as distinguished from the “Kritchevsky” type amine condensate.

SPAK DD-40 (Conc) is a blend of an anionic surfactant and a fatty acid ester. The former acts as a defoamer i.e. kills the foam formed and the latter acts as an antifoam i.e. reduces foam formation tendency. SPAK DD-40 (Conc) very well suits the fermentation system and has no adverse effect on yeast vitality and cell count. It is fully biodegradable and will not pose any problem in the effluent treatment plant. The fatty acid ester has a high molecular weight and will not distill off and contaminate the end product. Foam can be a disaster in fermentors because it frequently results in loss of production. In a biotechnology system the conditions for foam production are always potentially present. Many organisms generate proteins, which are released into the surrounding medium. The proteins and the CO2 liberated generate foam in the fermentation system.
