 Foreword  
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing qual ity 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 establis hed 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 an d 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 parties. 
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 procedures f or develop ment 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 standard s 
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.
