Thiodipropionic acid

Thiodipropionic acid (CAS 111-17-1), also known by the trade name Tyox A and abbreviated as TDPA, is a sulfur-containing dicarboxylic acid used industrially as an antioxidant and stabilizer.

Where is Thiodipropionic acid used?

• Food: E388 antioxidant protecting fats and oils from oxidative degradation
• Plastics and polymers: secondary antioxidant synergist extending service life of polyolefins and thermoplastics with hindered phenol primary antioxidants
• Personal care: stabilizer for lipid-rich creams and ointments against oxidative breakdown
• Pharmaceuticals: stabilizer in formulations and precursor in synthesis
• It is utilized where controlled reactivity of the thioether group is required.

Commercial specifications

• Food-grade material meeting E388 specifications
• Packaging from small quantities for specialty formulation up to bulk quantities for industrial polymer producers
