MOSH

Accumulation Concern

Physical properties of these saturated chains allow them to be easily absorbed by the body. High levels of mosh in food products are often traced back to the migration of white oils from plastic containers. The potential for long term health effects necessitates strict control over their concentration.

Sourcing Origin

Contamination can occur during resin production or during the moulding of the final part. Lubricants used in the maintenance of injection moulding machines are a common source of mosh in the production environment. Using food-grade lubricants reduces the risk of accidental exposure.

Screening Method

Laboratory separation techniques isolate the saturated fraction from the aromatic components for quantification. Detecting mosh involves sensitive analytical equipment that can measure parts per million in a complex polymer matrix. This testing is a standard part of quality control for food packaging suppliers.

Continuous monitoring of the supply chain ensures that any drift in the purity of the process oils is detected quickly. The results of these tests form the basis of the safety documentation required by food retailers.
