DL-Mandelic Acid Powder Manufacturers
The DL-Mandelic Acid produced by Kintainutri® is a white crystalline powder that is odorless or possesses a faint odor, its melting point typically falls within the range of 119°C to 121°C. Its density is approximately 1.30 g/cm³. This substance exhibits excellent water solubility, with approximately 150 grams of DL-Mandelic Acid dissolving in every 100 milliliters of water at 20°C. Additionally, it is highly soluble in organic solvents such as ethanol, diethyl ether, and isopropanol. It should be noted that our product is relatively sensitive to light, prolonged exposure to light can easily lead to discoloration and decomposition. Therefore, it is typically necessary to store the product away from light. If you are looking to make a purchase, we can supply DL-Mandelic Acid powder with a purity specification of 98–99% or higher, please contact us to request a free sample.

How To Make DL-Mandelic Acid Powder?
DL-Mandelic Acid Powder Benefits
Mandelic acid for skin
Mandelic acid exfoliation
DL-Mandelic Acid is a gentle alpha-hydroxy acid that possesses dual lipophilic and hydrophilic properties. It promotes the natural shedding of dead skin cells by loosening intercellular connections; specifically, it disrupts desmosomal protein structures—thereby loosening the adhesion between old, dead keratinocytes—though its exfoliating efficiency decreases significantly at a pH of 4.5. Studies have shown that after two weeks of using products formulated with mandelic acid, the surface area of blackheads decreased by 25.75%, whiteheads decreased by 36.10%, and the proportion of dead skin cells dropped by 83.04%, all without causing any irritant reactions. DL-Mandelic Acid powder is suitable for use by cosmetic and skincare manufacturers as a raw material in products such as serums, ampoules, and skin-resurfacing solutions.
Mandelic acid for hyperpigmentation
DL-Mandelic acid powder is a high-purity alpha-hydroxy acid (AHA) widely utilized in the fields of skincare and pharmaceutical intermediates. Its mechanism for improving acne and hyperpigmentation is primarily attributed to its gentle regulation of keratin metabolism and its role in skin remodeling. DL-Mandelic acid promotes the shedding of dead skin cells and reduces pore blockage, thereby lowering the risk of acne formation; concurrently, it accelerates epidermal turnover, aiding in the fading of post-inflammatory hyperpigmentation.
Studies further indicate that it enhances skin elasticity and firmness—effects likely linked to the stimulation of collagen-related remodeling, as well as improvements in the skin barrier and tissue structure—thereby further optimizing skin texture and mitigating signs of photoaging. Kintainutri®’s DL-Mandelic Acid powder features excellent lipid solubility and low irritancy, demonstrating potential utility in the treatment of common skin concerns such as photoaging, uneven pigmentation, and acne. It is ideally suited for incorporation into skincare formulations designed for skin brightening, spot reduction, and anti-acne care.
Mandelic acid antifungal
Mandelic acid boasts a long history of application as an antimicrobial agent, exhibiting inhibitory effects against a wide range of pathogenic bacteria—including Staphylococcus aureus, Escherichia coli, Proteus species, and Pseudomonas species. Its antimicrobial activity is concentration-dependent, it helps suppress the proliferation of acne-associated bacteria, aids in maintaining the balance of the skin's microecology, and contributes to a reduction in skin blemishes.
Furthermore, as an organic acid, topical application of mandelic acid rapidly lowers the pH of the skin's surface—thereby acidifying it—and suppresses the growth of odor-causing bacteria. Thanks to its potent antimicrobial capabilities and its inherent aromatic ring structure, our DL-Mandelic Acid powder is ideally suited for use in the formulation of deodorants and skincare products.
Potential for future contraceptive applications
DL-mandelic acid exhibits significant sperm-immobilizing activity, leading to disruptions in sperm energy metabolism while causing relatively minor damage to the integrity of the sperm plasma membrane and acrosome. Regarding vaginal irritation, the pathological scores for mandelic acid gel were significantly lower than those of traditional surfactant-based spermicides, demonstrating a low potential for vaginal irritation. Consequently, Kintainutri®s DL-mandelic acid is considered a promising non-surfactant contraceptive agent that combines both safety and efficacy.
What Is DL-Mandelic Acid Powder Used For?
Mandelic acid has garnered significant attention within the cosmetics industry for its potent exfoliating properties, thereby driving advancements in skincare technology. Due to its exceptional lipophilicity and gentle nature, DL-mandelic acid powder enjoys widespread application in both the skincare and pharmaceutical sectors. In the realm of skincare, it serves as an ideal solution for addressing conditions such as rosacea and folliculitis, its powerful antibacterial and anti-inflammatory capabilities effectively alleviate redness and swelling while inhibiting pathogens—a benefit notably demonstrated in mandelic acid peels.
Furthermore, thanks to Mandelic acid powder non-irritating profile, pleasant scent, and other beneficial attributes, it is frequently formulated into deodorants. As a highly effective exfoliating agent, its relatively large molecular weight ensures gradual skin penetration, thereby accelerating cellular turnover and refining rough skin texture with minimal irritation. Additionally, it demonstrates outstanding efficacy in treating hyperpigmentation, effectively fading dark spots and acne marks.
DL-Mandelic Acid Powder Safety
The Cosmetic Ingredient Review Expert Panel assessed the safety of 21 parabens as cosmetic preservatives. It was reported that all of these ingredients are used as preservatives in cosmetic products, however, five of them were also reported to be used as fragrance ingredients. The Expert Panel reviewed data relevant to the safety of these ingredients under the conditions of use reported in cosmetic formulations. The Panel concluded that, of the 21 parabens listed in this report, 20 are safe for use in cosmetics under current practices and concentrations, provided that the total concentration of parabens in any given formulation does not exceed 0.8%.
Side Effects Of DL-Mandelic Acid Powder
As an alpha-hydroxy acid, DL-Mandelic Acid powder—when utilized in cosmetic and pharmaceutical raw materials—commonly presents side effects such as skin irritation, redness, peeling, or a mild burning sensation, particularly at high concentrations or during initial use. For individuals with sensitive skin, it may trigger dryness, tightness, or a stinging sensation. Furthermore, this ingredient may increase the skin's sensitivity to ultraviolet (UV) radiation; therefore, enhanced sun protection measures are required during its use. In non-professional settings, direct inhalation of the powder may irritate the respiratory tract or mucous membranes. Additionally, care should be taken to avoid contact with the area around the eyes.
