Repelling and complexing: Bayer reveals new ingredients

Germany-based Bayer Chemicals, a division of Bayer AG, is to present new formulations for the detergents and cosmetics industry at the 50th SEPAWA (the Association of Soap, Fragrance and Detergent Specialists) conference taking place from the 8 to 10 October in Bad Dürkheim, Germany.

Bayer revealed in a statement last week that the presentation will focus on products from the company's Baypure range - complexing agents and dispersants that are environmentally friendly and readily tolerated by organisms - as well as its Bayrepel insect repellent ingredient.

For cosmetic applications Bayer will be demonstrating its Baypure CX 100 which is designed for use in soaps to prevent them from becoming rancid. The company's Baypure DS 100 product's ability to disperse sunscreen pigments will also be demonstrated at the show using a sample formulation.

According to Bayer, other suitable applications for the Baypure range include liquid detergent additives and the stabilisation of hydrogen peroxide in liquid detergents for special hygiene-related requirements, enabling the substitution of phosphonates.

The company's active ingredient Bayrepel (1-(1-methyl-propoxycarbonyl)-2-(2-hydroxyethyl)piperidine) will also be introduced for use in 'cosmetically attractive' formulations for insect repellents.

Bayer said the product was now available to all interested companies, for the first time, on a non-exclusive basis. Following the sale of the Bayer domestic insecticide business, the world-wide production and marketing rights for the insect repellant Bayrepel now belong to Bayer Chemicals.

The company claims that the Bayer active substance has several advantages over standard mosquito and midge repellents as it has virtually no smell, has no effect on materials and is well tolerated.

Bayer Chemicals is a division of Bayer AG, whose chemical operations have been managed by the former since July 2002. In 2002, Bayer Chemicals, which also encompasses the companies Wolff Walsrode and H.C. Starck, posted sales of €3.3 billion and an operating result of €160 million. Investments in 2002 totalled €285 million, with some €100 million being devoted to research and development.

Bayer Chemicals will be at stand 12/13 in the Salierhalle.
