Antioxidant DBHQ Application scenarios
1. Food Industry
Fats and Fried Foods: DBHQ is commonly used in vegetable oils, animal fats, and fried foods (such as potato chips and instant noodles) to effectively delay rancidity and extend shelf life.
Synergistic Effect: Often used in combination with other antioxidants (such as BHT and BHA) to enhance antioxidant effects, especially demonstrating stability under high-temperature processing conditions.
2. Industrial Applications
Lubricants and Fuels: Added to industrial lubricants, transformer oils, biodiesel, etc., to prevent the formation of oxidative deposits and maintain equipment stability.
Polymer Materials: Used in plastics (such as polyethylene and polypropylene), rubber, and adhesives to inhibit material aging and yellowing, and maintain mechanical properties.
Coatings and Inks: Prevents color changes or performance degradation caused by oxidation during film formation.
3. Cosmetics and Personal Care Products
Creams, Lotions, etc.: Protects oil-containing products (such as sunscreen and lipstick) from oxidation, maintaining color and efficacy stability.
4. Other Special Applications
Photographic Chemicals: Used as an antioxidant stabilizer for developers. Research and Laboratory Use: Used as an oxidation inhibitor or standard.
Precautions: Regulatory Restrictions: Addition to food must comply with national standards (e.g., China GB 2760, US FDA 21 CFR 172.185), typically limited to less than 0.02% of the fat content.
Storage and Handling: Store in a sealed container away from light and avoid contact with strong oxidizing agents.
DBHQ is particularly suitable for high-temperature processing due to its high-temperature stability and low volatility. Specific applications require optimized formulation based on process requirements and regulatory restrictions.
