Vitamin C - Tetrahexyldecyl Ascorbate

Tetrahexyldecyl ascorbate may just be the vitamin C ingredient needed to make vitamin C products that much more easy to use and versatile. Tetrahexyldecyl ascorbate is a stable oil-based form of vitamin C. It is considered to be an analog molecule to L-ascorbic acid which is the form of vitamin C used by the body. 

If you’re researching tetrahexyldecyl ascorbate, you might be looking for clean yet effective skincare.  L-ascorbic acid has been found to improve the appearance and condition of the skin. The other forms of vitamin C tend to have a much lower potency and don’t get converted by the body to L-ascorbic acid as readily. This seems to not be the case for tetrahexyldecyl ascorbate. 

The other issues with L-ascorbic acid products are that they are often acidic, highly unstable, and can only be formulated in a water base. 

Unlike pure vitamin C products and serums, tetrahexyldecyl ascorbate is lipid or fat-soluble which means it dissolves in oil. Studies have suggested that tetrahexyldecyl ascorbate may penetrate better into the skin due to the fatty acid composition of its structure. 

The benefit of tetrahexyldecyl ascorbate compared to L-ascorbic acid is that it is far more stable, less irritating, and can be easily formulated into oil-based products. 

Tetrahexyldecyl ascorbate also pairs well with other forms of vitamin C such as L-ascorbic acid, mineral ascorbates, calcium ascorbate, magnesium ascorbate, and ascorbyl palmitate. It also can be used alongside or combined with retinol as well.
