The origin, testing & prevention
Nowadays much more time is spent in interiors than it was in the past. This requires standards for protecting human health and for clean living conditions. Nowhere have these standards been more stringent than in the car industry. The car’s interior is more and more a living room on wheels and subject to a diversity of influences on health and well-being from the materials applied that surround the driver and passengers.
Increased interior temperature of up to 120°C surface T, due to aerodynamic and stylistic demands, are not an exception when a car is left standing in full sun for some time. The high surface temperatures cause problems inperceivable as yellowing, shrinkage, or undesired ageing of parts of a car’s interior.
It is, however, the emission of low and medium volatile substances which creates a risk for health and well being.

The SmiTool Light and Heat already discussed the subject of heat yellowing and light fastness tests on leather. The current SmiTool explains the differences between subjective and objective assessments of tested leather and how to report test results for heat yellowing and light fastness.
On processed leathers it is sometimes observed that, over time, an undesired, white, milky film appears on top of the leather. This white layer often gives rise to debates on its origin and causes and, in some cases, leads to a claim for damages. This phenomenon is called ‘fatty spew’. The possible sources of fatty spew may be of diverse nature, they are similar in one respect. They always originate from high melting point substances.
