For An Ecological World

With respect to the increased importance of ecological factors in leather finishing production, to head towards the protection of consumer and environment, the usage of chemýcals threatenening environment has either been totally forbidden or restricted by means of European Council Directive on VOCs (Volatile Organic Chlorinated Solvent) 1999/13/EC and Calýfornýa Proposition 65. With this purpose new studies are being carried on. Ecological demands is the most important factor that drives to the new developments in leather finishing.

The effects of this situation on leather finishing are as follows:
1) National legislation covering ecology spreads world-wide as a result of globalisation.
2) Each industry branch (automobile, upholstery, shoe upper and garment leather) prepares a list of banned chemicals with respect to its potential risk.

Automobile Sector is well-informed and conscious about the properties of all raw materials and construction materials that it is using. These have also been determined by the individual automobile manufacturers association. Some of the materials that are hazardous to the environment are being used in finishing chemicals. The ecological demands on automotive leather and solutions to these demands are as follows: turn into water-based systems, pigments with high fastness that are free of heavy metals and production of polyurethanes that is free of N-methylpyrrolidone .

In Upholstery Sector, the situation is paralel to the automobile sector. In upholstery sector German Ral RG 430 quality guide lines and test methods are used as a basis.

Shoe upper and garment sector: The finishing chemicals that are used in this sector must also have high ecology standards. The regulations towards this subject in EU are made on alkylphenol and alkylphenol ethoxylates. (It is forbidden to produce and market materials that contain more than 0,1% ethoxylates.)

Similar to the "Öko-Tex Standard 100" labelling system used in textile sector, leather sector has developed the labelling system "leather produced in an environmentally acceptable way and tested for hazardous substances."

California Office of Environmental Health Hazard Assesment (OEHHA) has described the materials listed below as dangerous.
PHTHALATES [dibutylphthalate (DBP), di-iso-octylphthalate ( DEHP, DOP)]
NONYLPHENOL, ALKYLPHENOLS AND THEIR ETHOXYLATES
SHORT CHAIN CHLORINATED PARAFFINS (CPs)
FLAME RETARDANTS PBB (5-Bromophenyl ether and 8-Bromophenyl ether derivatives)
N-METHYLPYRROLIDONE (NMP; it has to be reduced; its usage is not totally forbidden yet)
HEAVY METALS [Chrom(VI), Lead, mercury, Arsenic, Antimon, Kadmiyum]
TRIBUTYL TIN
AZO DYES that can split of carcinogenic aromatic amines according to 2002/61/EG
SUBSTANCES of VERY HIGH CONCERN (SVHC) (CMRs cat. 1 and 2, PBTs, vPvBs)

These chemicals are used in the production of lacquer, pigment, binder and feel products. SARCHEM company thinks it is necessary for its leather finishing product range to be composed of environmental friendly products.

Being dependent on this principle and with respect to the determinations of Environmental Health Organisations, SARCHEM does not use any of the chemicals listed above that have the properties to threaten environment and health. As a result, by following new developments, we fullfill our responsibilities to our customers and users of our products.
