Triacontanol

Triacontanol for Foliar and Plant Growth Applications

Overview

Triacontanol is a long-chain fatty alcohol used as an active component in agricultural plant growth regulator formulations. Technical material is generally supplied as a white, scale-like crystalline powder, while finished products can be formulated as microemulsions, soluble liquids, soluble powders, or emulsifiable powder preparations.

Commercial technical-grade Triacontanol is commonly specified at 90%–95% TC. Lower-concentration finished formulations, including 0.1% products, are used for practical agricultural applications. Liquid formulations may appear colorless to pale yellow depending on the formulation system.

Triacontanol is used in products intended for foliar application, seed soaking, and compatible fertilizer formulations. Formulation design should account for its physical properties, concentration, dispersion behavior, and compatibility with other ingredients.

Technical Specifications

Functional and Formulation Characteristics

Triacontanol technical material is a concentrated raw material intended for further processing into agricultural formulations. Because the technical material and finished products have substantially different active concentrations, specifications should clearly identify whether the reported value refers to TC or a formulated grade.

Key formulation characteristics include:

• Available as 90%–95% technical material.
• Suitable for several liquid and powder formulation formats.
• Can be prepared as low-concentration agricultural products.
• Applicable to foliar and seed-treatment formulations.
• Can be incorporated into compatible fertilizer systems.
• Active content can be evaluated by HPLC.

Triacontanol has limited direct compatibility with some water-based systems, making formulation design important. Suitable dispersion or formulation technologies may be required to achieve consistent distribution of the active component.

Processing temperature, ingredient sequence, concentration, and other formulation components can influence finished-product characteristics. Stability and compatibility should therefore be evaluated using the complete formulation.

Application Context

Foliar formulations are an important application area for Triacontanol. Products can be designed for dilution and application according to crop-specific agricultural programs. Uniform dispersion is particularly relevant for maintaining consistent application at low active concentrations.

Triacontanol can also be incorporated into seed-soaking and other seed-treatment formulations. Concentration, treatment duration, formulation uniformity, and compatibility with additional ingredients should be considered during development.

In fertilizer formulations, Triacontanol may be combined with compatible components to create products integrating plant nutrition and growth-management inputs. Compatibility should be assessed under actual manufacturing, storage, dilution, and application conditions.

Agricultural formulations containing Triacontanol may be used in crop-management programs associated with vegetative development, photosynthetic activity, flower-bud development, and crop productivity. Actual field performance depends on crop type, growth stage, concentration, application timing, environmental conditions, and formulation design.

Application rates and product claims should follow the registration and regulatory requirements applicable to the intended crop and market.

Composition and Standardization

Commercial Triacontanol technical material is primarily standardized according to active content. Technical grades of 90%–95% TC are distinct from finished formulations containing lower active concentrations such as 0.1%.

Routine quality-control parameters include:

• Triacontanol content by HPLC.
• Melting point.
• Physical appearance.
• Formulation concentration.
• Batch consistency.

HPLC assay provides quantitative information on active content, while melting-point testing can support identity and quality evaluation of technical material. Buyers should review analytical methods and specification limits when comparing different grades.

A batch-specific COA can provide corresponding analytical results. Technical crystalline powder should be stored in tightly sealed packaging under dry conditions and protected from excessive heat and direct sunlight.
