NanoCalmin (2-(3-(4-hydroxyphenyl)propanamido)benzoic acid) – High-Purity Multi-Functional Skin Active by SRBio

Powder, suitable for advanced cosmetic and pharmaceutical formulations

Technical Specifications

Uncompromising Quality: SRBio‘s Manufacturing Excellence

Precision Purity Control

HPLC-UV/GC-MS Dual Verification: Purity is stringently controlled to ≥99.0% (tested per in-house and pharmacopoeia standards). Impurity profile monitored down to 0.05% to ensure batch-to-batch consistency and formulation reliability.

Heavy Metal Screening: ICP-MS analysis confirms conformity with global cosmetic regulations: Lead (Pb) < 2 ppm, Arsenic (As) < 1 ppm, Mercury (Hg) < 0.1 ppm, Cadmium (Cd) < 0.1 ppm.

Residual Solvents: GC-FID analysis verifies absence of residual solvents, complying with ICH Q3C guidelines for topical applications.

Advanced Synthesis & Purification Technology

Optimized Synthesis Route: Proprietary multi-step organic synthesis using high-purity precursors to minimize side reactions and by-product formation. The synthesized compound is structurally similar to the antihistamine drug Tranilast, enabling potent antihistamine, antioxidant, anti-irritant, and anti-inflammatory activities.

Controlled Crystallization Process: High-vacuum distillation followed by low-temperature, multi-solvent recrystallization yields a consistently pure, white to off-white crystalline powder with a sharp melting point.

Eco-Impact: Our closed-loop solvent recovery system reduces VOC emissions and solvent waste by over 85% compared to conventional batch processes, supporting your green formulation goals.

Stability & Shelf-Life Superiority

Accelerated Stability Data: Formulated in a standard oil-in-water emulsion and tested under ICH conditions, NanoCalmin retains ≥98% potency after 24 months at 25°C/60% RH and 6 months at 40°C/75% RH.

Thermal & Oxidative Protection: Supplied in nitrogen-flushed, light-protective, vacuum-sealed foil packaging to prevent degradation and ensure formulation-ready integrity. Cold chain shipping is recommended to maintain optimal stability.

Scientific Evidence: Mechanism & Efficacy

Anti-Inflammatory Mechanism

NF-κB Pathway Inhibition: NanoCalmin exhibits multifunctional anti-inflammatory activity by inhibiting the degradation of IκB-α (the inhibitor of nuclear factor kappa-B) and preventing the phosphorylation of the p65 protein subunit of NF-κB in keratinocytes—directly blocking the initiation of the inflammatory cascade at the molecular level. This mechanism effectively reduces inflammatory immune responses and alleviates neurodermatitis-related skin reactions.

Antihistamine & Anti-Itch Activity

Histamine Receptor Modulation: NanoCalmin acts as an antihistamine agent that effectively reduces itching and redness by inhibiting histamine-induced skin reactions. Clinical studies have demonstrated its ability to significantly reduce the frequency of itching associated with contact dermatitis and neurodermatitis, with no reported side effects. The compound effectively blocks histamine release, showing a pronounced effect on relieving itching and inflammation through active antihistamine activity.

Antioxidant & Anti-Aging Protection

UV-Induced Damage Prevention: NanoCalmin has demonstrated the ability to inhibit UV-induced skin damage and aging by regulating ROS production, MMP expression, and key signaling pathways. By inhibiting ROS generation and MMP expression, it protects skin collagen from UV-induced degradation, helping prevent and improve skin photoaging.

Skin Brightening & Even Tone

Melanin Inhibition: Hydroxyphenyl Propamidobenzoic Acid is particularly effective in brightening the complexion and improving skin tone while also offering protection against environmental damage. Its ability to inhibit melanin production helps reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone. The compound’s strong antioxidant properties further facilitate the elimination of melanin and free radicals, improving dullness and yellowish complexion.

Triple Anti-Irritant Benefits

NanoCalmin delivers a triple-action soothing effect: reduces redness, inflammation, and itch, with added antioxidant efficacy for comprehensive skin protection. It has been proven through clinical tests to effectively inhibit histamine-induced skin erythema, edema, and pruritus, showing a particular effect on relieving itching and anti-inflammatory response.

Key Benefits Summary

• Rapid Antipruritic Relief: Quickly alleviates itching, irritation, and burning sensations in sensitive or reactive skin

• Anti-Inflammatory Response: Reduces skin erythema and inflammation through NF-κB pathway inhibition

• Antihistamine Activity: Effectively blocks histamine release to prevent allergic reactions

• Skin Barrier Support: Supports barrier recovery in dry, atopic-prone, or over-exfoliated skin

• Antioxidant Protection: Neutralizes free radicals and protects against oxidative stress

• Skin Brightening: Inhibits melanin production for improved skin tone uniformity

• Anti-Scarring Potential: Exhibits antifibrotic (anti-scarring) effects for comprehensive skin healing

For Best Results

Add at the low-temperature stage (below 40°C) during formulation to preserve bioactivity. Recommended dosage: 0.5–5.0% depending on application and desired efficacy intensity.

NanoCalmin is water-soluble and compatible with most cosmetic formulations, including emulsions, serums, gels, creams, and lotions. It exhibits no known comedogenicity and is considered safe for use during pregnancy.

Safety & Regulatory Compliance

Toxicological Profile

Comprehensive safety evaluations have been conducted across multiple endpoints, including acute oral/dermal toxicity (LD50), skin and eye irritation/corrosion, skin sensitization, phototoxicity, photoallergy, genotoxicity, repeated-dose toxicity (NOAEL/BMD), reproductive and developmental toxicity, and chronic toxicity/carcinogenicity. Studies confirm no cytolysis or toxicity under standard test conditions.

Safety Advantages

Unlike many synthetic anti-inflammatory agents, NanoCalmin:

• Exhibits no genotoxicity under standard testing

• Shows no evidence of skin sensitization in clinical evaluations

• Demonstrates favorable safety margin for long-term topical use

• Contains no known risk substances within the specified purity grade
