 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governi ng quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
The Community has established an East African Standards Committee  (EASC)  mandated to develop and 
issue East African Standards  (EAS) . The Committee is composed of representatives of the National 
Standards Bodies in Partner States, together with the representatives from the public and private sector 
organizations  in the community .  
East African Standards are developed through  Technical Committees that are representative of key 
stakeholders including government, academia, consumer groups, private sector and other interested part ies. 
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the 
Partner States. The comments received are discussed and incorporated before finalization of standards, in 
accordance with the Principles and proce dures for development of East African Standards.  
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible for this document is Technical Committee EASC/TC 071, Cosmetics and related 
products . 
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such patent rights.  
This third edition cancels and replaces the second  edition ( EAS 335:2013 ), which has been technically 
revised.

 Annex  A 
(normative)  
 
Determination of alcohol content  
A.1 Reagents  
A.1.1  Sodium chloride  
A.1.2  Hexane  
A.1.3  Sodium hydroxide, 1 N  
A.1.4  Phenolphthalein (solid)  
A.2 Procedure  
Take 25 mL of the sample, accurately measured at 25 °C, in a separator. Add 100 mL of water and mix. 
Saturate this mixture with sodium chloride, then add 100 mL of hexane and shake the mixture vigorously for 
2min to 3 min. Allow the mixture to stand for about 15 min to 20 min. Run the lower layer into the di stillation 
flask, wash the hexane in the separator by washing vigorously with about 25 mL of sodium chloride solution, 
allow to stand and run the wash liquor into the first saline solution. Make the mixed solution just alkaline with 
sodium hydroxide with s olid phenolphthalein as indicator. Add a little pumice powder and 100 mL of water. 
Distil and collect not less than 90 mL of distillate into a 100 -mL volumetric flask. Adjust the temperature at 
25°C and dilute with water to 100 mL at the same temperature. Determine the specific gravity at 25 °C. Find 
the percentage (v/v) of ethyl alcohol corresponding to the specific gravity by reference to the ethyl alcohol 
tables*. This figure gives the alcohol content of the distillate. Multiply by 4 to get the percentag e of ethyl 
alcohol in the sample.

 Annex  B 
(normative)  
 
Determination of stability of smell  
B.1 Procedure  
Put some pieces of bleached gauze of dimensions 5 cm x 10 cm, which have been pre -washed in hot wat er 
without soap and dried, into a porcelain cup and pour 1.5 mL of cologne into this cup. After the gauze gets  
soaked, take it out with the help of pincers. Without squeezing it, dry it in a premise having temperature 37 °C 
± 2 °C, and humidity of 65 % ± 5  % for 12 h.  
B.2 Results  
The product shall be taken to have passed the test if after the 12 h, the smell of cologne can be clearly picked  
up. DEAS 335:2021

 Annex C  
(normative)  
 
Determination of cloud temperature  
C.1 Procedure  
Pour 20 mL of cologne into a wide cylinder a nd close it with a plug. Insert a thermometer having scale up to  
–20 °C. Immerse the thermometer into the liquid in such a manner that its bulb is situated at the same  
distance from the bottom and walls. Immerse the cylinder containing the liquid into a co oling mixture  
containing ice and salt. After cooling the sample to 5 °C, take out the cylinder, shake it and scan it in  
transmitted daylight, or in the light of a 40 W electric lamp.  
C.2 Results  
The product shall be taken to have passed the test if no turb idity appears at a temperature of 5 °C. The  
cologne should be transparent.                     DEAS 335:2021
