Introduction
STANDARD ANALYTICAL PROCEDURE (SAP) OF RAW MATERIAL TWEEN 80 (POLYSORBATE 80) is a not unusual place nonionic surfactant, emulsifier and solubilizer this is utilized in a huge form of industries and applications. TWEEN 80 (POLYSORBATE 80) is generally utilized in meals products, cosmetics, medications, nutrients and vaccines. There may be many motives a organization may also want to decide the precise quantity of polysorbates of their fabric. For instance, groups may also want to decide a limits of their products, validate analytical techniques for product manufacturing or require the records for opposite engineering purposes. Thus, a well-evolved analytical approach is important for correctly quantitating polysorbates.
Due to the chemical shape and chemical houses of TWEEN 80 (POLYSORBATE 80), it can’t be correctly quantitated via way of means of analytical techniques such flowline chromatography or liquid chromatography with ultraviolet absorption. Since polysorbates do now no longer comprise a UV chromophore, this doesn’t offer enough chromatography. However, Charged Aerosol Detection (CAD) can offer a standard detection this is unbiased of the chemical shape for lots chemicals, together with polysorbates. This paper discusses an analytical approach evolved via way of means of Impact Analytical to offer a unmarried height for quantitating polysorbate eighty. The analytical approach that changed into evolved is capable of quantitate the quantity of WEEN 80 (POLYSORBATE 80) in a pharmaceutical system containing TWEEN 80 (POLYSORBATE 80), lively ingredient, microcrystalline cellulose (CMC) and sodium carboxymethyl cellulose.

Analytical Method
A preceding analytical approach the usage of High Performance Liquid Chromatography (HPLC) with Charged Aerosol Detection (CAD) did now no longer offer enough chromatography to quantitate for TWEEN 80 (POLYSORBATE 80). The TWEEN 80 (POLYSORBATE 80) requirements and samples had been organized in methanol. A Cadenza-C18, three μm, 4.6 x 50 mm column changed into used for the approach with a 0.5 mL/minute flow charge for a complete run time of 23 minutes. A methanol and water gradient changed into used for the analysis. The calibration curve used for quantitation with this approach supplied a linear curve and a R2 fee of 0.9850.
A TWEEN 80 (POLYSORBATE 80) USP preferred changed into used to expand the analytical approach similarly to gain a unmarried height via way of means of the usage of HPLC/CAD. The TWEEN 80 (POLYSORBATE 80) USP preferred changed into used to put together requirements starting from 107 μg/mL to 323 μg/mL in acetonitrile. The calibration curve used to quantitate TWEEN 80 (POLYSORBATE 80) is supplied. The calibration curve suggests linearity and a R2 fee of 0.9988. The device approach used an Inertial ODS-3, 5μm, 4.6 x a 150 mm column managed at a temperature of 40 °C. The cell section changed into isocratic with 50 Acetonitrile and 50% water with 2 ml ammonium acetate. The float charge changed into 1 mL/minute and a complete run time of 6 minutes. An instance chromatogram of a polysorbate eighty USP preferred at a attention of 215 μg/mL is proven in Figure three. The Polysorbate eighty USP preferred supplied a unmarried height to quantitate the quantity of TWEEN 80 (POLYSORBATE 80). A system pattern changed into analyzed with the progressed analytical approach to expose a height.

5.3 Physical Analysis
5.3.1 Test of Physical Form:
Check the sample and confirm its physical form; it should be clear oily liquid.
5.3.2 Test of Colour:
Confirm the colour of the sample with naked eye; it should be yellowish or brownish yellow.
5.3.3 Test of solubility:
It should be miscible with water, with absolute ethanol, with ethyl acetate and with methanol.

Take 5 gm of sample and add 25 ml of a mixture of equal volume of ethanol (96%) and ether that has been neutralized with 0.1M Potassium Hydroxide VS using 0.5 ml of Phenolphthalein Solution R1 as indicator. When the substance has completely dissolved, titrate with 0.1M Potassium Hydroxide VS, shaking constantly until a pink color that persists for at least 15 seconds is produced.
Calculations:
Calculate the acid value from the expression: 5.610 x V/W
Where “V” is the volume, in ml, of Potassium Hydroxide solution required and “W” is the weight, in gm, of substance taken.

5.3.7 Hydroxyl value
Take about 2.0 g accurately weighed in a 150-ml acetylation flask fitted with an air condenser and add 5.0ml of acetic anhydride solution R1. Heat for 1 hour in a water-bath, maintaining the level of the water about 2.5 cm above the level of the liquid in the flask throughout. Remove the flask and condenser, allow to cool and add 5 ml of water through the top of the condenser; if this causes cloudiness, add sufficient pyridine to produce a clear liquid, recording the volume added. Shake the flask, replace in the water-bath for 10 minutes, remove and allow to cool. Rinse the condenser and the walls of the flask with 5 ml of ethanol (96%), previously neutralised to phenolphthalein solution R1. Titrate with 0.5M ethanolic potassium hydroxide VS using 0.2 ml of phenolphthalein solution R1 as indicator. Repeat the operation without the substance being examined.

it should be not more than 10.
5.3.9 Saponification value
Dissolve 35 to 40 g of potassium hydroxide in 20 ml of water and add sufficient ethanol (96%) to produce 1000 ml. Allow to stand overnight and pour off the clear liquid.
Weigh 2 g of the substance into a 200-ml flask, add 25 ml of the ethanolic solution of potassium hydroxide and boil under a reflux condenser for 1 hour, rotating the contents frequently. While the solution is still hot, titrate the excess of alkali with 0.5M hydrochloric acid VS using 1 ml of phenolphthalein solution R1 as indicator. Repeat the operation without the substance being examined.
Calculate the saponification value from the expression 28.05v/w
