Retinal Powder CAS 116-31-4

Retinal powder, which is the component closest to retinoic acid, is formed by the oxidative cleavage of beta-carotene. Reduction yields retinol, and oxidation yields Retinal. Retinal is a co-factor of rhodopsin. In visual cells, 11-cis Retinal and opsin form visual pigments. After absorbing light, 11-cis Retinal isomerizes into all-trans Retinal, causing changes in the conformation of rhodopsin and initiating neural impulses to the brain, thereby forming vision.

Retinal is an important signal transduction molecule in eye development and it plays a variety of different and significant roles in the eye development of vertebrates. Retinal in the retina, this 11-cis-retinaldehyde is produced by enzymatic reaction from all-trans retinaldehyde or 11-cis-retinol (a new vitamin Ab). The optic pigment contained in the sensory cells of the retina. Visual pigments are a type of visual substance produced in the animal kingdom during the evolutionary process of natural selection to adapt to specific light environments. Their chemical nature is actually a pigment protein with chromophores as the auxiliary group.

Retinal powder is a skin care active ingredient that has anti-wrinkle, anti-aging and anti-acne effects. Studies show that compared with other commonly used vitamin A derivatives (for example, tretinoin), Retinal is less irritating to the skin and is more suitable for sensitive skin. In addition, Retinal, after being metabolized in the human body and converted into retinoic acid, also has the effect of treating acne. It can be said to be a multifunctional active additive.
