Tranexamic Acid Cetyl Ester Hydrochloride

Product Overview

This product is a next-generation, high-end cosmetic-grade targeted whitening active ingredient. Utilizing an advanced catalytic two-step synthesis process, a hexadecyl long chain has been successfully introduced into the traditional tranexamic acid molecule. Through precise control of the micro-crystallization process, residual organic solvents and low-melting-point impurities are completely eliminated, ensuring excellent thermodynamic stability and extended shelf life in high-end cosmetic formulations. It serves as an ideal drop-in replacement and upgrade solution for top-tier international skincare brands seeking painless, deep-acting, and long-lasting skin brightening effects.

Product Specifications

Core Mechanism & Formulation Advantages

Potent Targeted Brightening: As a unique lipophilic esterified derivative of tranexamic acid, it slowly releases upon skin absorption under the action of esterases. It efficiently targets and modulates UV-induced melanocyte activity, blocks melanin transfer to the stratum corneum, and combats chronic hyperpigmentation.

Superior Lipophilic Penetration (Deep Delivery): The engineered introduction of a cetyl (C16) long chain completely overcomes the limitations of traditional water-soluble tranexamic acid, which struggles with skin permeation. Its excellent lipophilicity allows it to easily penetrate the intercellular lipid barrier, reaching the basal layer of the skin and exponentially boosting absorption rates.

Premium Crystalline Stability (Solving Formulation Pain Points): Rigorous reaction control ensures a precise melting point range (131°C–135°C), confirming the complete absence of free residual wax or unreacted impurities. This fundamentally eliminates risks associated with conventional analogs, such as gelation, phase separation, discoloration, or abnormal crystal precipitation in emulsions during high-temperature processing or long-term storage, guaranteeing superior sensory feel and visual stability for end products.

Detailed Applications & Usage Guidelines

Key Application Areas

Advanced Intensive Spot-Correcting Serums: Targets stubborn melasma, age spots, and post-inflammatory hyperpigmentation (PIH). Leverages its high permeability to address pigmentation at the source, providing long-term at-home recovery following clinical aesthetic procedures.

Anti-Photoaging & Brightening Creams: Addresses dullness from fatigue, uneven skin tone, and UV damage. Its mild, non-irritating profile makes it ideal for daily full-face brightening creams applied over large areas.

Post-Sun Care & High-Performance Body Lotions: Rapidly soothes UV-induced erythema and inflammatory responses, prevents tanning, and promotes overall body skin clarity and radiance.

Eye Care Products: Improves dark circles caused by pigment deposition. Its low irritation potential perfectly suits the delicate eye contour area.

Formulation Synergy Recommendations

To achieve multi-pathway, maximum brightening efficacy, this ingredient exhibits excellent synergistic effects when combined with the following mainstream actives:

With Niacinamide: Blocks melanin transfer (Niacinamide) while inhibiting production at the source (this ingredient), creating a classic "block-and-suppress" golden brightening duo.

With Vitamin C Derivatives: Enhances antioxidant capacity, delivering rapid radiance alongside long-term spot reduction.

With Soothing Botanical Extracts: A reparative brightening approach tailored for sensitive skin, minimizing the risk of post-inflammatory hyperpigmentation.

Processing & Incorporation Guidelines

Recommended Usage Level: 0.5% – 1.0% for daily brightening/maintenance; 1.0% – 3.0% for intensive spot-correcting formulations.

Processing Tips: This lipophilic powder exhibits excellent compatibility with O/W (oil-in-water) systems. It is recommended to incorporate it into the oil phase, heat to 80°C – 85°C until fully melted and clear, then mix with the aqueous phase for homogenization and emulsification.

Optimal pH Range: Demonstrates peak chemical stability in formulations with a pH between 5.0 and 7.0.

Packaging & Storage Conditions

Storage Requirements: Store in a tightly sealed container, protected from light, in a cool and dry place. Strictly prevent moisture exposure. After opening, use promptly or reseal under nitrogen atmosphere.

Shelf Life: 24 months from the date of manufacture when stored under specified conditions.

Direct Manufacturer & Proprietary Continuous Flow Technology Advantages

As the direct manufacturer of this lipophilic brightening active, NINGBO INNO PHARMCHEM CO.,LTD. leverages independently developed and custom-designed tubular continuous flow reactors to achieve seamless scale-up from lab-scale trials to hundred-kilogram batch production. This process route offers exceptional batch-to-batch consistency and inherent safety, completely eliminating the thermal accumulation risks and impurity fluctuations associated with traditional batch reactor methods. Offering a perfect drop-in replacement for premium personal care-grade whitening ingredients and NIKKOL benchmark analogs, we sincerely invite trading companies, brand owners, and formulators to establish long-term strategic partnerships and jointly expand the high-value-added cosmetic raw materials market.
