Beauty & Healthcare Biopackaging for Biocosmetics Article contributed by Alessandro Ferlito, Commercial Director, Novamont, Novara, Italy The increasing problems of environmental pollution in recent years have caused even the world‘s large chemical companies to intensify their research and development in the area of new eco-friendly plastics. The cosmetics sector is also moving in the same direction, testing and perfecting packaging made of bioplastic polymers, above all for their organic-ecological lines. With its Mater-Bi brand, Novamont is manufacturing and commercialising a number of lines of biopolymers which contain vegetable components and conserve the chemical structure generated by chlorophyll photosynthesis, using oil from specially-selected crops (such as sunflower and rape seed). Certainly the best-known fields of application for Mater-Bi are eco carrier bags used to replace traditional shopping bags as well as bags for the collection of the organic component of wet household waste. But there are many more bioplastics applications developed by Novamont. Various grades of biopolymers have been developed which allow a variety of processing techniques and conversion into different products. The cosmetics sector is promising and demand from clients for these natural lines is becoming significant, although further testing is needed to determine which grades of Mater-Bi adapt best to the different areas of this application. Certainly its resistance to fats and oils make Mater-Bi suitable for containing loose powders or creams. A few years ago Novamont launched a partnership with Montalto Natura, a world natural cosmetics leader, to develop the use of Mater-Bi in cosmetics packaging. Montalto Natura cosmetics, certified by the CCPB, do not contain synthetic colours, silicone, lacquers, petroleum derivatives, or harmful preservatives. Their raw materials are of vegetable origin and are not tested on animals, and where they come from the less developed parts of the world, the company ensures that those involved in their harvesting and processing have not been unfairly exploited. The addition of low environmental impact packaging which is healthy to process, as well as completely biodegradabale and compostable, provides an added value to the product itself. The packaging used for the RosaLuna line of make-up also has aesthetic properties as least as appealing as those of traditional plastics. 18 bioplastics MAGAZINE [02/09] Vol. 4

Beauty & Healthcare Natural Floss Picks Cereplast, Inc., from Hawthorne, California, USA, recently announced that it will supply DenTek ® , a leading oral care company from Maryville Tennessee, USA, with bioplastic resin for its new Natural Floss Picks, the first biodegradable/compostable floss pick on the market. DenTek decided to manufacture its Natural Floss Picks using Cereplast Compostables ® resin based on biodegradability/compostability and technical characteristics. The bio-based resins are formulated from ‘building block’ resins such as PLA from NatureWorks. On their website, DenTek describes the handle of the dental floss picks as being made of starches from sustainable American crops like tapioca, potatoes, and wheat. The material is just as durable as petroleum-based plastic, but decomposes in less than 180 days in commercial composting facilities. “We developed the Natural Floss Pick based on consumer, customer and employee feedback, as well as our continuing commitment to creating environmentallyfriendly oral care products,” said Lex Shankle, VP of Marketing at DenTek. “Cereplast’s bioresins provided us with a way to create this first-of-its-kind green floss pick without sacrificing quality or performance.” Natural Floss Picks deliver the same high-quality flossing experience that is expected from DenTek floss with approximately one-third less waste. The handles are certified to be 100% compostable by the Biodegradable Plastics Institute (BPI), and the packaging is made from 100% recyclable material. Since its inception in 1982, DenTek has focused on providing innovative oral care products for professionals and consumers. The company began with the Dental Pik, and now offers over 25 products designed for health care professionals and oral health zealots. DenTek’ products go beyond brushing and provide solutions for flossing, braces care, teeth grinding, jaw pain and much more. Biodegradable Tampon Wrap Biodegradable and compostable NatureFlex from Innovia Films is widely used for the wrapping of feminine hygiene products, including digital tampons. It provides exceptional wrapping machinability due to its combination of high moisture barrier sealant layer to aid product protection, natural deadfold, wide heatseal range and static-free properties. The cellulose-based film can be used together with tear-tapes (including those manufactured from NatureFlex films) or alternatively it can be ‘scored’ to provide a ‘tear-tape-free’ easy opening feature. In addition, NatureFlex film has been tested to the Miti standard (ISO14851) which confirms it will biodegrade successfully in a waste-water environment. One of the leading European producers of feminine hygiene products, TOSAMA has switched to using glossy and transparent NatureFlex NE30 film to wrap its Viriana range of tampons. Based in Slovenia, TOSAMA says its use of NatureFlex responds to consumer demand for more eco-friendly packaging from renewable resources. Virana tampons bioplastics MAGAZINE [02/09] Vol. 4 19
