Tetrahexyldecyl Ascorbate

What It Does

Say hello to stable Vitamin C! Our Oil Soluble Vitamin C is one of the most studied active vitamin C ingredients in the world. Ultra stable, this Vitamin C ester is a proven antioxidant, shown to help clarify and brighten the skin and stimulate collagen production. It also helps reduce the damaged feel of hair.

Formulating with plain old ascorbic acid has many drawbacks - it is notoriously unstable and has poor availability for use in skin. This means formulators must use more, leading to irritation. Oil Soluble Vitamin C is considered an active Vitamin C. It is extremely stable, making formulation easy. It also penetrates the epidermis three-fold compared to ascorbic acid, so you can use less with even greater results. When Oil Soluble Vitamin C is in contact with the skin, it separates into Vitamin C and Isopalmitic acid thanks to an enzyme called esterase.

Oil Soluble Vitamin C has been shown to:
- Reduce UV induced skin pigmentation (3% use level, in vivo, Quasi-Drug in Japan)
- Reduce the appearance of age spots (10% use level, in vivo)
- Increase collagen synthesis (0.1% use level, in vitro)

Oil Soluble Vitamin C can also be used at 0.5% in an oil serum applied to hair for cuticle repair. The ester in our Oil Soluble Vitamin C reacts with the amino acids of damaged hair and makes the hair more hydrophobic, leaving it feeling shinier and healthier.

How It's Made

Ascorbic Acid from non-GMO corn and synthetic Isopalmitoyl Chloride are combined through chemical synthesis to form tetrahexyldecyl ascorbate.

Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.

Satisfied with color and fit
Size: Small, Color: Light Purple
For the money, this is a good shirt. True, the material is a bit thin and there is a feeling of 'fragility' (loose threads here and there) but the color is nice, the texture is appropriate. The sizing is what I call "New American". I was a medium my whole life but supersizing has made me into a small. I haven't changed, Americans have grown bigger. I am six feet tall and a bit (180+ cm) and weigh 155 pounds (70kg and a bit). The small fits me just fine everywhere but the shoulders are just barely wide enough. If you have slightly wider shoulders but are similar to me otherwise, this may be too tight for you in that one place.
