Direct procurement pipelines for high-activity carrier matrices, pure organic compounds, and therapeutic-grade essential components, serving cosmetic, clinical, and industrial compound formulators.
In industrial flavoring, personal care, and therapeutic formulations, the sensory perception of "coolness" plays an essential psychological role. Traditional cooling molecules, predominantly L-menthol, achieve this sensory activation by physically interacting with the Transient Receptor Potential Melastatin 8 (TRPM8) ion channel—a temperature-sensitive receptor located on sensory neurons. Upon activation, the channel permits an influx of calcium ions, generating an action potential that the central nervous system interprets as a cooling sensation.
However, pure menthol possesses significant chemical disadvantages, including high volatility, a sharp, medicinal odor, skin irritation at higher concentrations, and low thermal stability. As a leading wholesale effective cooling agent manufacturer, Jiangxi Hairui Natural Plant Co., Ltd. supplies high-purity synthetic and plant-derived derivatives (such as WS-3, WS-23, and botanical terpenes) engineered to target the TRPM8 pathway selectively. These advanced physiological agents provide a clean, long-lasting cooling effect devoid of the undesirable aromatic and irritant footprints associated with crude menthol.

Herbal extracts are separated cleanly from plant matrices using modern extraction techniques. Supported by our 5,000+ acre self-owned raw material production base, guaranteeing excellent quality control from seed to delivery.
See More DetailsModern commercial cooling requirements demand compounds that can withstand thermal processes like extrusion, pasteurization, and baking without degrading or evaporating. Traditional cooling methods fail at these high temperatures, necessitating the use of synthetic cooling agents like carboxamides and alkyl-substituted amides.
WS-3 is derived from menthol-3-carboxylic acid. Through a series of reaction steps including chlorination and ethylamination, it is refined into a highly pure crystalline structure. WS-3 exhibits intense cooling activity primarily targeting the roof of the mouth and the tongue. Because of its high threshold of activation, it remains stable up to temperatures of 220°C, making it the preferred choice for high-heat confectionery and pharmaceutical tablet manufacturing.
Unlike WS-3, WS-23 is not structurally derived from menthol. Its acyclic structure permits a unique sensory pathway that avoids any trace of typical minty undertones. Formulators utilize WS-23 for its rapid, front-of-mouth cooling burst, which provides immediate sensory impact. Its low volatility, high solubility in glycol carriers, and thermal stability up to 180°C make it a standard cooling molecule in modern oral care, functional beverages, and vape formulations.
Founded in 2006, Jiangxi Hairui Natural Plant Co., Ltd. is a high-tech enterprise specializing in the R&D, production, and global export of premium natural plant essential oils, carrier bases, and advanced synthetic cooling compounds.

Hairui Natural Plant only offers natural, safe, effective, and scientifically backed products that are manufactured and tested through rigorous quality control procedures.
Hairui Natural Plant has invested abundant resources on the upgrading of QA/QC standards and innovation levels, improving our core competitiveness on quality control and R&D.
From strict raw material selection to final delivery testing, our 9-step quality control process ensures premium quality and quick support for optimized solutions.
B2B procurement of cooling agents requires balancing physiological performance, regulatory compliance, and formulation stability. Modern chemical sourcing teams look beyond price per kilogram; they prioritize reliable technical specifications and consistent delivery protocols.
Formulators often struggle with the poor solubility of crystalline cooling agents in aqueous systems. WS-3, for example, is insoluble in water but highly soluble in ethanol, propylene glycol, and natural essential oils. Selecting the proper carrier matrix is critical to preventing recrystallization, which can cause gritty textures in cosmetics or uneven cooling spots in foods and oral care products.
Combining synthetic molecules like WS-23 with natural cooling agents, such as peppermint essential oil, yields a well-balanced sensory profile. The natural terpenes in peppermint oil provide an immediate cooling burst, while the synthetic molecules extend the duration of the sensation for up to 30 minutes without the bitter aftertaste associated with high concentrations of natural menthol.
Our extraction facility utilizes advanced vacuum molecular distillation to isolate pure natural molecules without high-heat degradation. This process ensures our cooling compounds and essential oils retain their natural structure, reducing the need for synthetic stabilizers in final formulations.
Essential oils and active cooling compounds are utilized across diverse industries, from agricultural pest control to premium cosmetics, high-performance pharmaceuticals, and aromatherapeutics.
Sweet orange oil, a natural terpene extract, is an eco-friendly pesticide and adjuvant. It promotes crop leaf respiration and photosynthesis while effectively controlling pests and diseases, offering clear economic and environmental benefits.
