Complying to USP39 – Storing light sensitive liquids

Certain liquids are light sensitive, their molecules have weak bonds that can break apart when exposed to light and make them ineffective. Bleach is good example of this, as standard bleach is always sold in a white plastic bottle to prevent from light degradation and prolonging it’s effective life.


Azlon have created opaque wash bottles specifically dedicated for sodium hypochlorite, bleach. Made in LDPE these prevent light spoilage and feature the new Globally Harmonised Symbols, NFPA diamond, risk phrases and safety information printed on the bottle for easy access.

To prevent light degradation Azlon have also created these amber polypropylene bottles with black screw caps. These have been made to comply to USP39 – a standard for light penetration. The leak proof, liner-less design has smooth inner contours for efficient pouring and ease of cleaning. They are made from Polypropylene which provides a good general resistance against chemicals and can be autoclaved at 121°C.
