Today, the use of antimicrobial substances in disinfection and preservation is governed by a large number of laws and regulations. Many of the available active ingredients are subject to limits on the maximum concentration in which they can be used. In addition, we must be aware of the ever-stronger influence of public discussions regarding even those preservatives deemed safe by legislation. A common problem is that no sufficient effects can be achieved with the remaining active ingredients in the allowable amounts, and thus the effectiveness of their application can be uncertain for the user. Through the concept of targeted selection of additives, schülke can increase the performance of the active ingredients in our products in order to achieve the greatest possible effects with the smallest amounts. The combinations developed in this manner allow active antimicrobial substances to be used more safely within legal limits.
Through new findings, additional restrictions on the number and quantities of substances with antimicrobial effects are constantly arising. What was considered non-hazardous yesterday could be regarded as a concern in its current application tomorrow. The continuous observation of the market, the media, and legislative activity makes it possible for schülke to respond to these challenges and provide suitable substitutes in a timely manner.
For example, traditional products for the preservation of cosmetics using a base of parahydroxybenzoic acid esters (parabens) such as euxyl® K 300, which have been under discussion and statutory reassessment since 2004, are being replaced by our product euxyl® PE 9010. Trends over the last few years show both a decrease in the use of euxyl® K 300 and an increase in the use of euxyl® PE 9010, which is due not only to the replacement of euxyl® K 300 but also to the exchange of similar products on the market.
If the total amount of euxyl® PE 9010 produced in 2013 had been used to replace products such as euxyl® K 300 at the same concentration, nearly 500 tons of parabens could have been saved.
Also, in the preservation of technical products such as emulsion paints, schülke succeeds in significantly increasing the performance of preparations through the appropriate combination of antimicrobial agents. In the case of parmetol® MBX, depending on the conditions of use and quality of resources, up to 50% of the previously used amount of the conventional substance combination can be spared through the use of a fast-acting third active ingredient without compromising the safe, long-term effect.
As long as concentrates are diluted to usable solutions by the consumer, questions of health protection, dosage accuracy, and environmental protection remain open. To solve this problem, hygiene technology developed special dosing devices that were not only made with these factors in mind, but also to last.
Variations in dosage that result from manual solution creation, often with the motto “more is better,” thus unnecessarily polluting the environment, increasing costs, and possibly influencing the effectiveness of the solution, are sustainably eliminated through dosing devices.
Dosing devices also ensure increased work safety because proper dosing with a dosing device eliminates the possibility of skin or eye contact with the concentrate, for example.
We are currently marketing the “dosit® des”. This is a microprocessor controlled measuring device that is produced according to the latest environmental protection and occupational safety requirements. It functions according to the current guidelines of the Robert Koch Institute (Robert Koch-Institut, RKI) and the recommendations of the Association for Applied Hygiene (Verbund für angewandte Hygiene, VAH). schülke had this confirmed by the accredited test institution HygCen - Center for Hygiene and Medical Product Safety Ltd. (Centrum für Hygiene und medizinische Produktsicherheit GmbH) under the leadership of Mrs. Dipl.-Ing. (FH), Margrit Werner and Dr. Heinz-Peter Werner.
Other aspects such as energy consumption, durability, stocking of spare parts, and the eventual disposal of old equipment are taken into account in the development and production of our dosing devices. The microprocessor control allows the implementation of new requirements, for example from the VAH, and the ongoing monitoring of dosing accuracy. Through the availability of different languages in the dosit® des display, we guarantee safety in the use of our equipment even for foreign language speakers.
As part of maintenance contracts, schülke does not merely provide a good customer-supplier relationship. Above all, we ensure compliance with the prescribed maintenance intervals, check dosing, and – to the greatest extent possible – keep devices technically up to date for our customers.
The customer can thus be confident that schülke is the right partner for sustainable, economical, and efficient dosing.
