Recently, in the fields of beauty care, pharmaceutical formulations, and industrial biotechnology, 1,3-Dihydroxyacetone (referred to as DHA for short)—a polyol compound with natural coloring, moisturizing and repairing, and bioactive properties—has continued to be a "popular active raw material" in formula development across various industries, thanks to its safe and mild characteristics and multi-scenario adaptability. As a naturally occurring ketose in nature (commonly found in glycerol fermentation products, sugarcane juice, honey, etc.), DHA not only breaks the limitations of traditional tanning ingredients such as "reliance on ultraviolet rays and strong irritation" but also, with its advantages of "low sensitization, easy degradation, and multi-functionality", plays an irreplaceable role in artificial tanning, skin care, pharmaceutical intermediates, and industrial catalysis. It has become a "key bridge" connecting natural raw materials and high-value-added end products.
In terms of the product's essence, 1,3-Dihydroxyacetone is the simplest ketose, with a chemical formula of C₃H₆O₃. Its core structure contains two hydroxyl groups (-OH) and one ketone group (C=O). This "dual hydroxyl + ketone group" molecular configuration endows it with three major properties: water solubility, reactivity, and biocompatibility. At room temperature, DHA appears as a white to off-white crystalline powder with no obvious odor. It is easily soluble in polar solvents such as water, ethanol, and glycerol, with a melting point of approximately 75-80°C. It has good stability in neutral or weakly acidic environments (pH 4.0-6.0) but is prone to decomposition when exposed to strong alkaline substances or high temperatures.
Based on different preparation processes, DHA can be divided into "bio-fermentation type" and "chemical synthesis type": The bio-fermentation type is produced by microbial fermentation (e.g., Acetobacter, Pseudomonas) using glycerol as the raw material. It features high purity (up to 99% or above), low impurities, and retained natural activity, making it suitable for high-safety-demand fields such as beauty and pharmaceuticals. The chemical synthesis type is prepared through chemical processes such as hydroxyacetone oxidation and propylene glycol dehydrogenation. It has advantages of low cost and stable production capacity, and is widely used in the industrial sector. Regardless of the type, high-quality DHA must undergo special tests for heavy metals and microorganisms to ensure safety and applicability. After years of scientific research and industrial verification, relying on its core advantages of "natural coloring, mild moisturizing, and high bioactivity", DHA has demonstrated outstanding efficacy in four major fields—beauty tanning, skin care, pharmaceutical intermediates, and industrial catalysis—becoming a "multi-functional active ingredient" for cross-sector applications.
In the field of artificial tanning, DHA is globally recognized as a "safe and effective coloring ingredient". Its core mechanism of action is to undergo the "Maillard reaction" (non-enzymatic browning reaction) with proteins (e.g., keratin) in the skin's stratum corneum, generating brown melanoidins. This forms a natural and uniform "tanned" effect on the skin surface. Importantly, this coloring only acts on the stratum corneum and does not penetrate deep into the skin, causing no irritation to melanocytes. It thus avoids the risks of skin aging, pigmentation, and even skin cancer that may be caused by ultraviolet radiation.Compared with traditional tanning ingredients (e.g., carotenoids, synthetic pigments), DHA coloring has three major advantages: First, high naturalness. The coloring effect gradients from light brown to dark brown, simulating the body's natural tanning process without issues such as "artificial-looking tan" or "uneven color". The color can last for 7-10 days (fading with the normal metabolism of the stratum corneum). Second, strong safety. Certified by authoritative institutions such as the U.S. FDA and EU cosmetic regulatory authorities, DHA has extremely low skin irritation when added in compliance with regulations (concentration: 2%-15%), making it suitable even for sensitive skin. Third, wide adaptability. It can be applied in various dosage forms such as self-tanning lotions, sprays, mousses, and wipes. Moreover, it can be compounded with moisturizing ingredients (e.g., hyaluronic acid) and sunscreen ingredients (e.g., zinc oxide) to achieve the "three-in-one" effect of "tanning + moisturizing + sun protection". Currently, DHA serves as a core ingredient in the self-tanning product lines of major global beauty brands (e.g., Clarins, Shiseido, Maybelline), accounting for over 80% of the market share.
Beyond its tanning function, DHA also exhibits excellent moisturizing and repairing capabilities in daily skin care. The two hydroxyl groups in its molecular structure can form hydrogen bonds with moisture in the skin's stratum corneum, effectively locking in moisture. At the same time, it forms a thin moisturizing film on the skin surface to slow down moisture evaporation, making it particularly suitable for people with dry or dehydrated skin. Clinical tests show that a moisturizing lotion containing 3%-5% DHA can increase the moisture content of the skin's stratum corneum by 20%-30%, with the moisturizing effect lasting for 4-6 hours.
In addition, DHA can promote the normal renewal of stratum corneum cells and help repair damaged skin barriers. For skin with damaged barriers caused by over-cleansing or frequent exfoliation, DHA can regulate the arrangement of intercellular lipids in the stratum corneum, enhance the density of the stratum corneum, reduce the penetration of external pollutants and irritants, and alleviate skin problems such as redness, dryness, and flaking. Currently, some sensitive skin-specific brands have added low-concentration DHA (1%-3%) to repairing creams and serums as an auxiliary ingredient for mild moisturizing and barrier repair, which has been widely recognized by consumers.
In the pharmaceutical industry, DHA is an important bioactive intermediate. Relying on its unique chemical structure, it can be used to synthesize a variety of therapeutic drugs, and is widely applied in the research and development of drugs for diseases such as diabetes and tumors. For example, "dihydroxyacetone phosphate (DHAP)", synthesized using DHA as the raw material, is a key intermediate in the glucose metabolism pathway. It can be used to develop blood sugar-regulating drugs to help improve glucose metabolism disorders in diabetic patients. In addition, DHA can be chemically modified to synthesize derivatives with anti-tumor activity. These derivatives can inhibit the energy metabolism of tumor cells and induce tumor cell apoptosis, providing new ideas for the research and development of new anti-tumor drugs.
Meanwhile, DHA also has applications in the field of medical dressings: Medical sponges made by compounding DHA with biomaterials such as chitosan and gelatin not only have good water absorption and breathability but also can promote wound healing. DHA can activate the activity of skin fibroblasts, accelerate collagen synthesis, and shorten the wound healing cycle, making it particularly suitable for the care of superficial wounds and burn wounds.
