Undecylenoyl Phenylalanine
The Advanced Signal Blocker and Whitening Potency Amplifier
Undecylenoyl Phenylalanine is a powerful cosmetic-grade active that acts as a primary signal blocker for melanogenesis. By specifically targeting the alpha-MSH (Melanocyte Stimulating Hormone) receptor, it serves as an essential “potency amplifier” for brightening formulations, effectively addressing stubborn dark spots and persistent hyperpigmentation.

High-Purity Undecylenoyl Phenylalanine: Farnesol-Free Upstream Melanin Antagonist
Formulating elite hyperpigmentation correctors and professional spot-treatment lines requires lipophilic signal-blocking actives that intercept melanogenesis at the receptor level without inducing contact dermatitis or destabilizing lipid matrices. Manufactured by Shaanxi Huatai Bio-Fine Chemicals Co., our Cosmetic-Grade Undecylenoyl Phenylalanine is meticulously refined to maintain a strict 100% farnesol-free profile.
Functioning as a sophisticated Alpha-MSH receptor antagonist, this high-purity lipoamino acid competitively blocks hormonal pigmentation cues before they activate the tyrosinase enzyme, delivering clinical-grade radiance and pigment clearance for hyper-reactive skin architectures.
Clinical Efficacy & Pharmacological Performance (MoA)
Upstream Signaling Interception: Acts as a targeted Alpha-MSH antagonist to halt hormonal melanogenesis initiation prior to tyrosinase activation.
Clinical Pigment Reduction: Clinically documented to outperform traditional tyrosinase inhibitors in reducing the intensity of stubborn dark spots and lightening overall skin tone within a 6 to 8 week continuous application protocol.
Sensitivity Downregulation: Pharmacological evaluations confirm a 40% reduction in key epidermal irritation markers within 48 hours, establishing an impeccable safety profile for compromised barriers.
Technical Data & Physical Specifications Engineered to eliminate manufacturing friction for OEM/ODM innovators, this high-purity lipoamino acid dissolves smoothly into heated oil phases, yielding an absolute water-white, odorless profile that ensures zero formulation discoloration.

Formulation Directives & Synergistic Matrices As a lipophilic active, Undecylenoyl Phenylalanine requires integration into the heated oil phase (approximately 80°C) to ensure full dissolution and optimal biological compatibility. Best maintained within a pH range of 5.0 – 7.0 in finished formulations.
| Target Application | Recommended Dosage | Companion Actives & Mechanistic Synergy |
| Targeted Spot Correctors | 1.0% – 2.0% | Active + Allantoin: Combines upstream Alpha-MSH signal blocking with water-soluble cellular micro-trauma healing to rapidly fade localized pigment clusters. |
| SOS Barrier Brightening | 1.0% – 1.5% | Active + Panthenol: Panthenol floods the stratum corneum with deep hydration, creating a non-reactive environment for hormonal melanin suppression without dryness. |
| Translucent Radiance Care | 1.5% – 2.0% | Active + Ceramide NP: Halts melanogenesis at the signaling stage while Ceramide NP physically reconstructs the depleted surface lipid cement for absolute barrier protection. |
