Formulation Engineering Lab

The formulation characterization laboratory, liquid formulation laboratory, and solid formulation laboratory conduct functional validation according to different dosage forms and application scenarios. Focusing on active ingredients and scientific compounding for synergistic effects, we rigorously verify formulations, efficacy, and technologies during R&D to ensure every Sobel product achieves the 1+1>2 principle of ingredient-formula synergy, creating precisely effective functional products.

SST Formulation Technology

By combining specific materials with active components of humic acid, SST effectively reduces molecular surface tension. This technology enables humic acid to synergistically penetrate soil pores rapidly and act directly on plant root surfaces. Through this mechanism, humic acid diffuses uniformly in the soil along with water movement, binding with clay minerals and metal oxides to form organo-mineral complexes. This process not only enhances soil aggregate stability but also increases cation exchange capacity (CEC), thereby significantly improving soil water retention and nutrient-holding capacity.

SST technology facilitates coordination adsorption between carboxyl/phenolic hydroxyl functional groups and soil minerals to form humic acid-mineral complexes. These complexes competitively chelate fixed metal ions in soil, releasing bound nutrients while electrostatically delaying the leaching of NH₄⁺/K⁺, thereby optimizing the bioavailability of rhizosphere nutrients.

The reduction of surface tension and contact angle enables rapid spreading across soil and crop surfaces.
