Our Homeland Bavaria 

Origin and starting point 

Geretsried, the headquarters of the RUDOLF GROUP, ca. 30 km in the south of Munich near the Lake Starnberg, lies 

inbetween the capital Munich - the centre of art, culture and innovation with its universities –

Environmental management system according to ISO 14001 

For a long time our thinking and action has been focused on 

saving resources for a better environment. In 1997, as one of 

the first companies, we introduced the environmental 

management system according to the international standard 

DIN EN ISO 14001. Together with the quality management 

system according to DIN EN ISO 9001, which was first 

certified in April 1993, it forms an important part of the futureoriented 

and international business policy of our company. 

Our environment report informs customers, neighbours and 

interested circles of our current environmental data. 

. 

RUDOLF‘s ecological aim when developing, producing and applying chemical products 

includes the economical use of resources, such as energy, water, raw materials and the 

lowest possible environmental pollution due to effluent, air emissions and waste. For 

implementing these aims, we advise our customers in detail how to use our products in an 

environmentally friendly way. 

The ISO-certified quality management system is the basis of our environmental 

management system. It shows our employees‘ standards to provide high-quality 

performance and to thus fully satisfy customers. 



Awards 

Our environment 

Think ahead for sustainability 

RUDOLF was awarded a special award for renewable raw materials 2007 by the Bayerische Staatsministerium für 

Landwirtschaft und Forsten (Bavarian state ministry for agriculture and forestry) as well as C.A.R.M.E.N. e.V. 

(Centrales Agrar-Rohstoff-Marketing- und Entwicklungs-Netzwerk e. V. = Central Agrarian Raw Material Marketing 

and Development Network, registered organisation). This honours the many years of our exemplary commitment to 

the environment.

1.) Natural based softeners 



A non-suitable „solution“ 

Aloe Vera softeners on 

textiles 

� Aloe is water-soluble, 

it is not wash-fast 

� Heat in the drying process 

destroys the aloe 

� Aloe evaporates in the dryer 

Result: 

After drying Aloe could not 

be detected on the textile. If it 

is dried under moderate 

temperatures, it is not wash-fast. 

Nice story but no effects

Hydrophilic: 

Natural healthy 

wearing comfort 

RUCOFIN LAN provides a natural 

comfortable climate when wearing 

the textile and offers comfort of 

the highest degree using the 

combination of optimised textile 

softness and hydrophilic effect.

Tested and ecologically safe 

Schadstoffgeprüftes Textil 

RUCOFIN LAN complies with the most 

stringent standards for ecological textiles. 

Hence, it conforms to the Oeko-Tex Standard 

100 and Global Organic Textile Standard 

(G.O.T.S.). RUCOFIN LAN is highly suitable for 

use in : 

• bio-cotton, linen, wool, 

• botanic fibres like lyocell, viscose, modal, 

• natural raw material based polyester fibre 

like Ingeo

„Learning from nature 

as an impulse for an 

independent technical 

design".

NMP problem in aqueous PU coating 

NMP = N-Methyl-2-pyrrolidon, 

is used in old-fashioned manufacturing of acqueous PU dispersions as a cosolvent 

May cause harm to unborn child. (R61) 

Irritating to eyes, respiratory system and skin. 

(R36/37/38) 

Concentrations higher than 10 % - T (toxic), 

R61, R36/37/38; 

Concentrations higher than 5 % up to lower 

than 10 % - T (toxic), R61. 

Since february 2011 n-methyl-2-pyrrolidone 

(NMP) (CAS-no. 872-50-4) is proposed by 

ECHA as potentially candidate for the list of 

Substances of Very High Concern (SVHC-list).
