Biochem/physiol Actions

Retinyl palmitate is widely used in pharmaceutical applications.[1] It is also extensively used in cosmetic formulations due to its beneficial effects on the appearance of skin and anti-oxidant properties.[2] Retinyl palmitate acts as a teratogen and affect vertebrate embryogenesis and regeneration.[3] It is added as a source of vitamin A in low fat and skim milks.[4] Retinyl palmitate acts as a chemopreventive or antineoplastic agent.[5]
Bewertung: Vitamin-A-Metabolismus.

General description

Retinyl palmitate or vitamin A palmitate is a retinoid,[3] which is an acid form of vitamin A. Retinoids exist as many geometric isomers due to the unsaturated bonds in the aliphatic chain. Retinyl palmitate is a major storage form of vitamin A found in epidermis.[1] Retinyl esters provide pools of vitamin A that are converted into retinol and other retinoids as needed.[6]

Physical form

oil or solid

Packaging

Verschweisste Ampulle

Application

Retinyl palmitate has been used as a standard in high performance liquid chromatography (HPLC).[7] It has also been used to study its effect on brain regeneration in larval Xenopus laevis.[3]

Questions

  1. What is the difference in purity and melting point among Retinyl palmitate PHR1235, R3375 and R1512?

    1 answer
    1. The melting point of Retinyl palmitate is very close to room temperature, about 25-30°C. However, melting point is not part of the Quality Control (QC) specifications for any of the Retinyl palmitate products listed.
      The differences in purity testing for each is as follows:
      Product R1512 is assayed for potency in USP units per gram, but not purity. The minimum activity is 1.7M units per gram.
      Product R3375 is assayed for both potency in USP units per gram and purity by HPLC. The average activity is 1.8M units per gram. The minimum purity is 90%.
      Product PHR1235 is a Certified Reference Material (CRM) that is traceable to the USP primary standard and assayed for both potency in USP units per gram and purity by HPLC. Values are reported on a lot specific basis as compared to the current USP primary standard 1602502.
