What is Propyl Gallate CAS 121-79-9?

Propyl gallate (CAS 121-79-9), as a highly efficient oil-soluble antioxidant, is irreplaceable in food (especially oil products), medicine and cosmetics due to its ability to block lipid oxidation. Its advantages include:

Safety: Low toxicity (GRAS certified), but should be avoided in infant food and high-temperature processing scenarios. Synergistic effect: When compounded with BHA/BHT, it can enhance the effect and reduce the dosage of a single dose.

Usage Precautions:

Avoid contact with iron/copper containers (to prevent discoloration);

High-temperature resistant antioxidants (such as TBHQ) should be replaced in baked goods.

Propyl Gallate CAS 121-79-9 Use

1.Food Industry (Core Application)

Function: Oil-soluble antioxidant, interrupting the auto-oxidation chain reaction of oils and fats.

Permitted dosage (GB 2760 standard) :

Maximum addition amount for food category (g/kg)

Oils and fried foods: 0.1 (calculated by total fat)

Cured meat products and dried fish products: 0.1

Biscuits, instant noodles, quick-cooking rice: 0.1

Canned nuts, chewing gum candies: 0.1-0.4

Synergistic effect: When combined with BHA, BHT or citric acid, the antioxidant effect is enhanced.

2. Medicine and Cosmetics

Medicine: Protect liposoluble drug components and delay oxidation and deterioration.

Cosmetics: Antioxidants in face creams and essences (to prevent UV damage, with an addition amount of 0.2% - 5%).

3. Other fields

Feed: Protect unsaturated fatty acids and extend the shelf life (addition amount ≤0.01%).

Industry: Antioxidant stabilizer for lubricating oils and textiles.
