Introduction Light can speed up the chemical breakdown of some active ingredients. This is called photodegradation. It can reduce potency and, in some formulations, produce unwanted degradation products. Packaging is one of the simplest ways to limit light exposure. This article explains how light-protective bottles work, which materials are used and what to consider when…

Reuse at home: low-risk options If a bottle…
Bottle shape affects how well a pack fills, labels, ships and handles in daily use. The body shape is only one part of the decision. The neck finish, closure and glass colour often matter more. This article compares the four common body shapes and the practical points to check before choosing one. Common bottle shapes…
Introduction Sterilisation destroys or removes all viable micro-organisms, including bacterial spores. It is different from cleaning, which removes visible and chemical residues, and from disinfection, which reduces the number of micro-organisms but does not guarantee sterility. Which method suits a bottle depends on its materials, because glass, rubber and plastic tolerate heat, steam, chemicals and…
Introduction Pharmaceutical bottles range from a few millilitres to several litres, and the right size depends on the form of the product, the dose and how it is used. This guide gives typical size ranges, the factors that matter when choosing a size, and where dropper bottles fit in. Typical size ranges There is no…
Introduction A regular glass bottle is made to hold a product and look good on the shelf. A pharmaceutical bottle must also keep the contents stable, avoid reacting with them and, where required, show or prevent unauthorised opening. Differences in glass quality, light protection, closures and documentation follow from these requirements. Glass quality and chemical…
