E389 - Thiodipropionate de dilauryle

Origin

Dilauryl thiodipropionate (DLTDP) is a synthetic antioxidant. It is derived from thiodipropionic acid and lauryl alcohol (dodecanol). It is not naturally occurring and is manufactured through chemical synthesis.

Usage

DLTDP is primarily used as an antioxidant in plastics, rubbers, adhesives, and lubricants. In food packaging, it helps to prevent the degradation of the packaging material, thus indirectly protecting the food from oxidation and spoilage. It is particularly effective in polyolefins like polyethylene and polypropylene. It is used in combination with other antioxidants, such as phenolic antioxidants, to provide synergistic protection. It is not typically added directly to food, but its presence can be found in food due to migration from packaging materials. There is no ADI (Acceptable Daily Intake) established for DLTDP as its use is limited to food packaging.

Side Effects

DLTDP is considered to have low toxicity. Studies indicate that it is poorly absorbed from the gastrointestinal tract. However, as with any chemical substance, there is potential for allergic reactions in sensitive individuals. The main concern is related to potential migration from packaging into food. Regulatory bodies monitor the levels of migration to ensure they remain within safe limits. No significant adverse effects have been reported at the levels typically encountered in food packaging applications. However, comprehensive long-term studies on high-dose exposure are limited.
