Excellence for Experts Since 1968.

Since 1968 Koch‑Chemie stands for high-quality cleaning and care products in the fields of washing chemistry, detailing, workshop and industry. Tradition, which is characterized by constant improvements and attention to detail: Excellence for Experts. We are one of the few companies in our industry that researches, produces and sells its own products. 

Made in Germany.

At its company site in Unna, Germany, Koch‑Chemie employs about 140 people and is represented in Germany by about 30 sales representatives. From the product idea to production and sales, all processes Made in Germany are represented. Since 2020, Koch‑Chemie has also been actively bringing its quality standards to the USA with the founding of its sister company in Atlanta. 

Interna­tionally Networked.

Since 2017 Koch‑Chemie has been part of the French family business Novarc Group. The group is a global partner for customers in the automotive and electrical industries. Koch‑Chemie's own independent structure and identity continues to develop and benefits from the synergies within the group. The integration of Koch‑Chemie into a larger group of companies with a European and global orientation offers great advantages: the joint use of networks, product, purchasing and sales know-how as well as intercultural exchange.

Highest Quality and Environ­mental Protection.

As a system provider, Koch‑Chemie pursues the goal of offering its customers the highest quality, innovations and coordinated services. In doing so, the Company always ensures that it operates in harmony with regulatory, political and ecological requirements. Koch‑Chemie is also committed to these high quality, environmental and social standards through various Management Systems.

Alongside our products, we have also constantly developed our corporate culture over the past few years. Thus, six elementary KCX values have emerged from the cooperation and ideas of all Koch-Chemie employees, which significantly influence us in our daily and future-relevant decisions.
Sustainability is one of these six supporting pillars. A fundamental way of thinking that is lived by every single team member and implemented in all areas of our company.

Our sustainability strategy is divided into two main objectives. All measures pursue one of these endeavors:

  • Climate neutrality of the company
  • Environmentally friendly products

Honesty with Certificate and Label.

We have made a conscious decision to use independent, already established labels and certifications and not to develop our own test marks. Behind the external labels that distinguish our products are strict, transparent guidelines with maximum credibility and significance, as our processes and goals are regularly reviewed.

Environmental Goals with DIN EN ISO 14001.

As early as 1989, with the launch of the Star range, Koch-Chemie took a pioneering role in sustainability and launched products on the market in accordance with DIN standard 14001. Since then, environmental goals and the well-being of this very nature have been firmly rooted in our corporate philosophy and our entire environmental management system has been certified according to DIN EN ISO 14001.

Certificate DIN EN ISO 9001 & DIN EN ISO 14001:2015

We use surfactants from renewable raw materials in the production of the various washing and care products. Furthermore, all surfactants and complexing agents used are easily biodegradable – even beyond the strict legal requirements. In formulations and production, Koch-Chemie dispenses with questionable ingredients such as halogenated hydrocarbons, EDTA and APEO.

Conscious Environmental Protection.

Conscious environmental protection, strict adherence to laws and regulations and a complete quality and environmental management system ensure consistent top quality with the highest level of occupational safety. As a producer Koch‑Chemie knows 100% how the various products are composed. For the chemical manufacturer, the services also include ensuring that all customers and partners have the necessary documents for occupational safety and environmental protection. We provide meaningful and correct operating instructions, safety data sheets and accident leaflets. The consistent implementation of the Quality and Environmental Management Systems DIN EN ISO 9001 and DIN EN ISO 14001 is the prerequisite for worldwide manufacturer approvals.

In the spirit of continuous improvement, the Company is constantly developing the integrated Management System. For successful, goal-oriented work, it is essential that all employees can access this system easily and transparently at any time. This is the only way we can continuously develop our product quality and business processes with clear corporate goals and adapt to the dynamic requirements of the market and our company.

The Idea Behind the Product­ System.

10 Colors for 10 Product Groups.

Koch‑Chemie is a system provider with perfectly coordinated products. Our ProductSystem groups and sorts our portfolio of chemical products. The design of the system is based on the periodic table of the elements and thus emphasizes the core of the company: chemistry. The periodic table represents all known chemical elements, so that it serves as a comprehensive system that conveys multi-layered information. This is exactly what our ProductSystem pursues as well.

All chemical products are classified in one of the ten product groups. The product groups describe the fields of application of our chemistry. Each product group has its own color code for quick orientation and to avoid confusion. This code is also printed on the product label. Those who have been familiar with our ProductSystem for some time will be able to quickly assign or select the individual products while working.

Each product name is assigned an abbreviation, which is displayed in the ProductSystem. In combination with the color codes, it allows easy and quick orientation when working. The individual elements or abbreviations appear not only on the packaging but also in other media and are a further feature of our Koch‑Chemie language. As with the periodic table, the elements are equipped with additional information that describes further core properties of the product.

The superscript with the reference to the ph‑value is used for the quick classification of a product, especially with our cleaners. In the field of paint treatment our products are supplemented by other information. The subscripts 01, 02 etc. are the version numbers of the polishes and sealing products. They are consecutive and chronological. The superscript indicates the degree of abrasiveness of a product, the subscript indicates the degree of gloss. This information in the ProductSystem alone clarifies many product characteristics and allows products to be easily compared with each other.
