When looking for a perfumery or beauty product, the first thing to catch the eye is its container.... and the best material for that container, is glass. In this article Mark Devonald Smith examines why the importance of glass in cosmetics and perfumery packaging can't be overestimated. From the practical viewpoint, it is inert; there's no possibility of a reaction with the contents, or leakage of fragrance or other ingredient. Whatever the product, glass provides the perfect protection. Equally important is the cachet that glass can give. Its brilliance, translucence, weight and fell all say "quality" in a way that no other packaging material can match. The fact that glass is completely recyclable in our ecological age is another advantage.
