Avoidance of dermal exposure to preservatives by packaging

• Dermal exposure to chemicals in cosmetics and hygiene products (e.g. moisturising creams, soaps, shampoos) is increasingly recognized as an important area for risk assessment and regulation. The contents of such products is regulated by classification of exposure types (e.g. stay on/wash off) and regulatory concepts based on toxicological studies and manufacturing or market experience. Positive lists, negative lists or establishment of recommendations on concentration and exposure form a basis for consumer safety. Common problem areas are perfumes, preservatives and the formation of oxidation products after manufacture. A new patented system, suitable for packages from 100 ml to 5 l, with collapsible plastic bags and unique dosage valves prevents bacteria and air from entering the packaging. Thus the use of preservatives can be avoided. This may lead to a reduced risk of individual reactions to specific preservatives as well as cross-allergy reactions. The consumer no longer needs to hunt for strange names on small ingredient labels. Also, it could prevent the prospective development of allergy. The avoidance of oxidation products is another advantage.
