Chemical structure and physical properties of Ascorbyl Tetraisopalmitate

Ascorbyl Tetraisopalmitate is a derivative of ascorbic acid (vitamin C) and is commonly used in skincare products due to its stability and skin-friendly properties. Its chemical structure is as follows:

Key points about Ascorbyl Tetraisopalmitate:

1.Chemical Structure:

Ascorbyl Tetraisopalmitate is an ester formed from ascorbic acid (vitamin C) and isopalmitic acid.
The four isopalmitic acid chains attached to the ascorbic acid molecule contribute to its lipophilic (fat-soluble) nature.

Solubility: Ascorbyl Tetraisopalmitate is oil-soluble, making it suitable for oil-based formulations in skincare products.

Stability: It is known for its higher stability compared to pure ascorbic acid, which is prone to oxidation. This stability allows for a longer shelf life of products containing this derivative.

Penetration: The lipophilic nature of Ascorbyl Tetraisopalmitate enables better skin penetration compared to water-soluble forms of vitamin C, potentially providing more significant benefits to the skin.

3.Skin Benefits:

Antioxidant: Like ascorbic acid, Ascorbyl Tetraisopalmitate has antioxidant properties, helping to protect the skin from free radical damage caused by environmental factors like UV radiation and pollution.

Collagen Synthesis: It is believed to stimulate collagen synthesis, contributing to the maintenance of skin elasticity and firmness.

Brightening: Ascorbyl Tetraisopalmitate may contribute to skin brightening and reducing the appearance of dark spots and hyperpigmentation.

Ascorbyl Tetraisopalmitate is commonly found in various skincare products, including anti-aging creams, serums, and moisturizers.

It is often chosen for formulations where the stability of vitamin C is crucial, as it is less prone to oxidation.

While Ascorbyl Tetraisopalmitate offers advantages in terms of stability and skin penetration, individual skin reactions can vary. It’s always recommended to perform a patch test when trying new skincare products and consult with a dermatologist if you have specific skin concerns or conditions.
