3. Cosmetics Introduction & Sensory Properties
Cosmetology is the study and application of beauty treatment. Cosmetics is one of the branch of cosmetology.
Cosmetics are the products used for the purposes of cleansing, beautifying, promoting attractiveness or alternating one's appearance.
Sensory Properties Of Cosmetics
The properties which are detected by the five sense organs.

*Take Suitable aliquot of sample containing mg in 100 cm3 of beaker.
*Make it slightly acidic.
*Add 1 gm ammonium tartarate + 2 cm3 of 8-hydroxyuinoline.
*Dilute to 200 cm3 & het to 60-80oc.
*Neutralize excess of cid by slow adding NaOH till ZINC complexes .
*Add 15 cm3 of ammonium acetate , let the mixture acquire room temp.
*Adjust pH Decent through weighed gouch crucible .
*Wash the ppt with hot water.
*Dry the ppt. for 2 hours at C
Weight of ZINC = Weight of ppt. x

29. ESTIMATION OF CHLORIDE
Pipette out suitable aliquot of sample containing 100 mg of chloride into 250 cm3 of beaker.
Dilute it to 150 cm3 with distilled water.
Neutralize it with 1:1 NH4OH .
Acidify with 1:1 HNO3 till clear solution is obtained .(Its is added to prevent precipitate of phosphates & carbonates)
Add 0.1 N AgNO3 solution drop wise with constant stirring till excess of AgNO3 is present. Het to C .
Let the precipitate stand in dark for 1-2 hours. Filter the ppt. through previously weighed Gooch Crucible .
Wash the ppt. with 0.1N HNO3 till the ppt. is from Ag+ ion.
Dry the ppt. in Oven, Cool & weigh.
Calculate the amount of chloride by using following formula
amount of chloride = Weight of Ppt. X
