Indian StandardSPECIFICATION FOR KUSUM OIL

o. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Insti­tution on 24 November 1966, after the draft finalized by the Oilsand Oilseeds Sectional Committee had been approved by the ChemicalDivision Council and the Agricultural and Food Products Division Council.

0.2 KUSUM oil is obtained from the seeds of the tree, Schleichera oleosa(Lour.) Merr. syn. S. trijuga Willd., Fam. Sapindacese which is largelycultivated in the eastern parts. of India to serve as the host tree for lacinsects. .KUSUM tree is also known in Indian languages as KUSUMB,KOSAM PAKRA, POOMARAM, POOVAM and POSUKlJ.

0.3 KU.SUM oil is reputed to he the original macassar oil known for pro­motingthegrowthof hair. The oil has also medicinal properties. KUSUMoil can be used for soap making. The oil contains certain cyanogeneticglucosides and arnides, which cause evolution of hydrogen cyanide andammonia during soap making. Further, it gives a low yield of only about4 percent of glycerine.

0.4 KUSUM oil, so far has limited availability for industrial purposes.Its use may provide a cheap source for soap making and thus relieve pres­sure on some of the other vegetable oils. It will also provide extraincome to lac growers.

0.5 In the preparation of this standard assistance has been derived fromthe following publications:

DATTA (R L) and GHOSE (P K). Investigation of the oilof Kusum(Schleiche,a t,ijuga) and its application in soap making. Depart­ment of Indust,ies BtIU. so. Calcutta. 1931.

Kusum tree, seed and oil. 1959. Shellac Export PromotionCouncil, Calcutta.

0.6 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, express­ing the result of a test or analysis, shall be rounded off in accordance with15:,2-1960·. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

APPENDIX A

(Clause 3.3)

DETERMINATION OF COLOUR OF SOAP

A-O. GENERAL

A-O.I Principle of the Method - The oil is saponified with alcoholicsodium hydroxide, the alcohol is removed, and the colour of the residualsoap is assessed by visual examination.

A-I. APPARATUS

A-I.I Enamelled Beaker - one, lOO-ml capacity.

A-I.2 Water-Bath

A-2. REAGENT

A-2.t Alcoholic Sodium Hydroxide Solution - 25 percent solution(wlv). This solution shall be completely colourless.

A-3. PROCEDURE

A-3.t Take 20 ml of alcoholic sodium hydroxide solution in an enamelbeaker and immerse the beaker in the water-bath. When the alcoholbegins to boil, add 15 mlof the hot oil in thin stream, constantly stirringthe mixture with ~ glass rod. Take care to ensure that saponificationis complete. Evaporate off the alcohol as quickly as possible while stillstirring, and assess the colour of the residual soap by visual examination.

NOTE - A gentle stream of clean dry air facilitates the quick evaporation ofalcohol. The dry soap shall not be overheated or else the colour wiU deterio-n~ .
