Vitamin A aldehyde, also known as retinaldehyde, is the closest thing to an acid, and is produced by the oxidative breakdown of beta-carotene. Retinol is obtained by reduction and retinic acid by oxidation. Retinaldehyde is a coradical of rhodopsin. Visual fine In Chemicalbook cell, 11-cis retinaldehyde and visual protein constitute visual pigment. After absorption of light, 11-cis retinaldehyde isomerizes to full-trans retinaldehyde, which changes the conformation of rhodopsin and initiates nerve pulses to the brain, thus forming vision.
Retinaldehyde is an anti-wrinkle, anti-aging, anti-acne active component of skin care. Studies have shown that retinaldehyde is less irritating than other vitamin A derivatives commonly used (e.g., retinic acid) and is better for sensitive skin. In addition, retinaldehyde, which is metabolized by human Chemicalbook body, also has the effect of treating acne and can be said to be a multi-functional active additive. Retinaldehyde can be used in a variety of anti-wrinkle, anti-aging and anti-acne skin care formulations, with the recommended dosage being around 0.05% to 0.15%.
chromophores as its auxiliary base.Pure retinaldehyde solids are sensitive to UV light and easy to oxidize.They need to be protected from light and sealed at low temperatures.
