A new series of TPEs for cosmetic packaging from Kraiburg TPE is said to reliably meet standard requirements over the long term. The High Resistance TPO for Cosmetic series has enabled the company to expand its portfolio to include materials that withstand contact with particularly demanding ingredients, including isododecane. In the packaging sector, isododecane and similar substances are a challenge for TPEs. If a material has not been specifically developed for use in the field of cosmetics, there is a risk that modifications such as swelling or degradation of the material may occur. This particularly affects products that are based on water-resistant formulations.

For manufacturers, the requirements that cosmetic products have to meet are high, as product reliability has to be ensured at all times. But visual and haptic qualities, which have a direct influence on purchasing decisions, are also vitally important. Along with these criteria, mechanical properties also play a crucial role for processors. With its new TPE series, the company says it is now able to provide further solutions for the beauty market, including applications such as waterproof mascara, pipette lids, lip gloss applicators and cosmetics packaging.

This response for beauty applications is based on the company’s established TPE product Copec, which was developed to meet the requirements for high resistance to sebum oils. Due to its velvety surface, it also meets the demand for high-quality haptics in the field of consumer electronics. According to the company, prospective clients will also benefit from the broad range of processing options available with the materials. High Resistance TPE for Cosmetics is available with hardness grades of 65, 75 and 85 Shore A and can be customized in many ways due to its opaque color. These compounds also boast good processing properties in injection molding and allow adhesion to selected plastics. The materials also meet the standards of the cosmetics industry in accordance with US FDA CFR 21 and Regulation (EC) No. 10/2011 and comply with REACH, RoHS, California Proposition 65 as well as Mercosur No. 39/19. The TPEs are free of animal ingredients, so that they can be used throughout the cosmetics market.
