Protecting the potency of probiotics once the product has been opened is critical to their effectiveness. The Healthcare Packaging business unit of Clariant, a global manufacturer of specialty chemicals headquartered in Muttenz, Switzerland, recently introduced packaging technology that helps probiotics in nutraceutical products retain their potency and extends shelf life by inhibiting exposure to damaging oxygen, moisture and light.
“As probiotics are living, ‘good’ micro-organisms, it is essential to protect them from exposure to elements—oxygen, moisture and UV light—that can damage or kill the probiotics,” explained Stéphane Rault, Product Manager for Clariant Healthcare Packaging. “The optimal way to protect the most sensitive probiotics often involves a combination of ‘active’ and ‘passive’ solutions.”
Passive solutions are the first line of defense for probiotics. These can include packages with strong barrier properties, such as Clariant’s Oxy-Guard bottles. According to Rault, the unique structure of these six-layer, extrusion blowmolded containers offers several times the oxygen-barrier protection of standard, single-layer polyethylene bottles, plus enhanced protection from moisture and UV light.
Oxy-Guard bottles are compliant with US FDA and EU regulations for use in pharmaceutical and nutraceutical applications and are covered by a Drug Master File (DMF). Oxy-Guard bottles are available in a range of standard sizes, with neck finishes that accept pharmaceutical screw-cap products.
