Kojic acid dipalmitate Usage And Synthesis

Description

Kojic acid is a widely used skin lighten-ing agent as it inhibits catecholase activity of tyrosinase. Derivatives of kojic acid such as kojic acid dipalmitate are easilyabsorbed through skin and are more effective than kojic acid. kojic acid dipalmitate is an effective tyrosinase inhibitor that stunts melanin production, making it a powerful skin whitening agent. It can balance skin tones, fade dark spots, and eliminate free radicals.
kojic acid dipalmitate is a topical cream formulation indicated for the treatment of post-inflammatory hyperpigmentation, melasma and hyper-melanotic skin pigmentation disorders. Kojic Acid Dipalmitate can lighten the skin pigmentation and corrects discoloration in adults.

Chemical Properties

Kojic acid dipalmitate is a White to pale yellow powder, Soluble in oil, alcohol, mineral oil and esters (ethyl acetate). It is light and heat stable, while kojic acid tends to oxidize over time.
Kojic acid dipalmitate is stable within a wide pH range of 4-9, It is more easily absorbed into skin when it is incorporated into a cream as compared with kojic acid.

Uses

kojic acid dipalmitate is classified as an emollient, preparations containing kojic acid dipalmitate are said to inhibit uV-induced erythema.

Application

kojic acid dipalmitate is a diesterified derivative of tretinoin. It is considered superior to tretinoin in its whitening ability and is more stable than tretinoin in cosmetic formulations. It is commonly used in sunscreens and after-sun products, colour cosmetics, whitening products, anti-ageing products, creams and lotions.

benefits

Kojic acid dipalmitate has the advantage that it does not complex with metal ions, does not change colour, is light and heat stable and is compatible with most cosmetic ingredients. Therefore, in addition to whitening the skin, it has anti-aging properties, treats melasma, reduces scars, and has antibacterial (antifungal) benefits.

Mechanism of action

Kojic acid dipalmitate is able to inhibit skin pigmentation by inhibiting tyrosinase activity. Its ability to inhibit melanin formation makes it effective in whitening darker skin or darker skin areas. Its effect is enhanced when combined with glucosamine derivatives such as N-acetylglucosamine (NAG).
