Kojic Acid Dipalmitate / کوجک ایسڈ ڈائی پالمیٹیٹ

Kojic Acid Dipalmitate is a lipophilic ester formed by the double esterification of kojic acid with palmitic acid, a naturally occurring fatty acid found in palm and rice bran oil. Kojic acid itself was first isolated from Aspergillus oryzae during sake fermentation in Japan and has been used in cosmetics as a skin brightening agent since the 1980s. The dipalmitate form was developed specifically to address the significant stability and water-solubility limitations of the parent molecule, making it far more practical for modern cosmetic formulation.

What sets Kojic Acid Dipalmitate apart is its superior chemical stability combined with oil compatibility. Once incorporated into skin, it undergoes enzymatic hydrolysis and releases active kojic acid directly at the site of action. This targeted delivery mechanism allows it to inhibit tyrosinase — the enzyme responsible for melanin synthesis — with controlled efficiency while avoiding the rapid degradation and discoloration associated with free kojic acid. It also contributes mild antioxidant activity, reinforcing its value as a multifunctional brightening active in professional formulations.

Recommended Usage 

Skincare (Creams, Serums, Lotions)

This is the primary application for Kojic Acid Dipalmitate, where it functions as a core brightening active in both oil-in-water and water-in-oil emulsions. Incorporate at 1–3% into the oil phase at 60–70°C, or pre-dissolve in a carrier oil before blending into serums.

Haircare (Shampoo, Conditioner, Masks)

Kojic Acid Dipalmitate is not a standard ingredient in haircare and provides minimal benefit in this category. Not recommended unless formulating a scalp-specific hyperpigmentation treatment where oil solubility is an advantage.

Soap Making (Cold Process, Melt and Pour)

The high alkaline pH of cold process saponification will hydrolyze the ester and reduce brightening efficacy significantly. For melt-and-pour bases, dissolve at 0.5–1% in a small amount of carrier oil before blending for improved distribution and better results.

Body Care (Scrubs, Butters, Balms)

Performs very well in anhydrous body butters, oil-based scrubs, and balms due to its natural oil solubility. Use at 1–2% in body brightening formulas targeting elbows, knees, underarms, and areas prone to friction-related hyperpigmentation.

Functional Cosmetics (Deodorants, Sunscreen, Baby Care)

Can be incorporated into sunscreen formulations to provide combined UV protection and anti-pigmentation activity in one product. Not recommended for baby care; use with standard precautions in deodorant bases and keep concentration at or below 1%.
