 Foreword  
This Kenya Standard was prepared by the Cosmetics and related products Technical Committee (TC) under 
the guidance of the Standards Projects Committee, and it is in accordance with the procedures of the Kenya 
Bureau of Standards . 
The cosmetics industry is a very vibrant sector. New products and innovations are developed continuously, and 
there are no standards to cover such products.  One such range of products is the make -up range (foundation, 
concealers, eye shadow, glitters, etc ). The Cosmetics TC identified the need to have a general standard, against 
which all cosmetics products that do not have specific product standards can be tested.  This standard will 
enable manufacturers have a basis to gauge the quality of their products , as well as enable importers to trade. 
This standard will be very useful for purposes of trade facilitation, while ensuring the products are safe for use 
by the consumer. Cosmetic products should also function as intended. The Standard ensure s the quality , fitness 
for use and safety of the products to the consumers by having general/specific requirements addressing these 
aspects. The standard prescribe s specific crucial parameters such as raw material requirements, limits for heavy 
metal contaminants, and microbiological limits. The standard also make s reference to the labelling standard, 
thereby ensuring labelling requirements are adhered to. The standard also requires that the product shall be 
produced, prepared and handled under Good Manufacturing Practi ces (GMP) thus further assuring 
stakeholders of the quality and safety of the product.  
The standard will be used by stakeholders in the cosmetics sector, including manufacturers, importers, traders, 
testing bodies, research bodies, institutions of higher learning and regulatory bodies.  The standard will also be 
used for purposes of Quality Assurance, Product Certification, Inspection and Market Surveillance.
