Vitamin A Palmitate

Vitamin A palmitate, also known as retinol palmitate, is one of the most important vitamin A esters.

There are several specifications:

★ 100,000 units (content about 55%), mainly used as feed additives.

★ 170,000 units (content about 97%), used for cosmetics and pharmaceutical ingredient.

★ 500,000 IU/g, 250,000 IU/g powder form.

★ 1000000 IU/g, 170000 IU/g oil form.

★ Or other specifications.
In addition, it is also an important pharmaceutical intermediate and can be used to manufacture drugs.

Due to the instability of vitamin A, most vitamin A products on the market appear in the form of its esters.

Other vitamin A ester derivatives including vitamin A acetate and vitamin A palmitate are also available.
Vitamin A acetate is susceptible to moisture absorption, while vitamin A palmitate is more stable than vitamin A acetate.

The synthesis of vitamin A palmitate is mainly divided into two categories: chemical synthesis and biosynthesis. The chemical synthesis process is mature, but complex, requires high temperature and high pressure, has high requirements for equipment, has many side reactions, is difficult to separate products, has high energy consumption, and causes great environmental pollution.
The enzyme synthesis process is simple, has few by-products, low energy consumption, and is environmentally friendly.
