The cosmetics sector requires the setting up of cleanrooms and associated controlled environments in which we endeavour to control the concentration of airborne particles, the temperature, humidity and pressure.


This is a very diverse sector in light of its multiple activities (research & development laboratories, analysis laboratories, manufacture of cosmetic products, etc.).

A cleanroom is surrounded by its shell, a physical barrier made up of partitions, ceilings, doors and floors separating various (classified and/or unclassified) areas which have to meet a certain number of design criteria or very specific performance requirements (mechanical performance, geometry, ergonomics, fire hazard properties, sound proofing, etc).

In the health care sector, the following contamination risks and areas may be identified:

-          Protecting staff who could be contaminated by micro-organisms and particles,

-          Protecting the environment which could be contaminated by micro-organisms,

-          Protecting manufactured products which could be contaminated by micro-organisms and particles.

Since 2006, the cosmetics industry has relied on standards related to microbiological evaluations of its products. A cleanroom's design will have a direct impact on the safety of the environment or operators.

Materials that make up the shell of a cleanroom must primarily comply with requirements for airtightness, cleaning, resistance to disinfecting agents, non-retention of particles and non-proliferation of contaminating agents.

The standard NF EN ISO 14644 defines a cleanroom as being a "room in which the concentration of airborne particles is controlled and which is built and used in such a way as to minimise the introduction, production and retention of particles inside the room and in which other pertinent parameters such as temperature, humidity and pressure are controlled as necessary."
