Prevention of odour in car interior

Selected processes and chemicals taking care of air quality

Your TFL solution for better air quality in car interiors

Smell is our most intimate, individualistic sense and we are able to distinguish between >10‘000 different molecules. Until now, smell was probably the most ignored sense; now however, in the changing field of automotive interiors, the odour of leather may be the key to achieving a competitive advantage.

“Consumers care as much about their new car's smell as its horsepower”

Leather may contain some degraded residues from proteins, natural grease and impurities from chemicals used during the leather making process. These substances can be released into the car interior and detected as unpleasant odours.

The following substances in leather are recognised as “problematic“ and cause unpleasant odours in car interiors:

  • Amines: from protein degradation during beamhousing and waste-water recycling
  • Aldehydes: from the oxidative decomposition of natural fats and low quality fatliquors
  • Thio-compounds: trace levels originating from beamhousing, protein degradation and certain biocides

How to prevent the oxidation of natural fat and grease:

  • Metal ions contained in water and dyes may catalyse the oxidation of fats
  • Thoroughly degrease your raw material
  • Introduce fatliquoring agents to your wet-end process which contain radical inhibitors

How to prevent trace levels of amines and thiols:

  • Amines, mainly present in wet blue material can be de-activated
    • >> Use SELLATAN® WL-G.
  • Thiols can be substantially reduced in leather
    • >> Utilizing the TFL LS low sulfide technology, featuring products such as PELLVIT® LSG and ERHAVIT® LSU
  • Degradation of proteins can cause the formation of Amines and Thiols
    • >> Use SELLA® Tec DEO to minimize this risk
