Kojic Acid Dipalmitate

Description

Kojic acid dipalmitate is a derivative of kojic acid, created by esterifying kojic acid with palmitic acid. This compound is more stable than its parent compound and is primarily used in cosmetic formulations for its skin-lightening and antioxidant properties. Kojic acid dipalmitate is often favoured in formulations due to its lower irritation potential, making it suitable for sensitive skin.

Benefits

Stability: Kojic acid dipalmitate is more stable than kojic acid, allowing it to maintain its effectiveness over time and under various formulation conditions.

Skin Brightening: Like kojic acid, it inhibits the enzyme tyrosinase, reducing melanin production and helping to lighten hyperpigmentation and dark spots.

Antioxidant Properties: It protects the skin from oxidative stress and free radical damage, contributing to overall skin health and reducing signs of aging.

Moisturising Properties: The palmitic acid component offers additional emollient benefits, helping to hydrate and soften the skin. 

Uses

Cosmetic Products: Commonly included in skin-lightening creams, serums, lotions, and other topical formulations aimed at treating uneven skin tone and hyperpigmentation.

Sunscreens: Sometimes utilised in sunscreen formulations to enhance UV protection.

Skincare Treatments: Used in peels and masks for brightening and exfoliating effects, often in conjunction with other active ingredients.
