Boilers are crucial components in various industrial processes, providing steam for power generation, heating, and many manufacturing operations. To ensure their efficient functioning and longevity, it is essential to maintain the quality of boiler water. This is where boiler water treatment chemicals play a pivotal role. The treatment process ensures that the water remains free of contaminants that could lead to scaling, corrosion, or fouling, ultimately prolonging the service life of the equipment and improving operational efficiency.


Sevoflurane belongs to the class of volatile inhalation anesthetics, and its primary function is to induce and maintain a state of general anesthesia during surgeries or medical procedures. It exerts its effects by enhancing the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain. GABAergic neurotransmission reduces neuronal activity, leading to sedation and, in the case of sevoflurane, a state of general anesthesia.

Pyrroloquinoline quinone disodium salt (PQQ) is powerful supplement that support cellular health and energy production. PQQ is a unique compound that promotes the growth of new mitochondria in cells, enhancing energy metabolism and protecting cells from oxidative damage. When combined with coenzyme Q10, another essential nutrient for mitochondrial function, coenzyme Q10 PQQ can significantly boost energy levels and reduce fatigue. This combination is especially beneficial for athletes and individuals with high energy demands, ensuring that their cells function optimally.

4. Synergistic Formulation Unlike standalone supplements, Bonusan PQQ Meta Plus incorporates complementary nutrients, optimizing the efficacy of PQQ. This holistic approach can yield better results for those seeking comprehensive health benefits.


One of the primary functions of excipients is to enhance the stability of the API. Many APIs are sensitive to environmental factors like humidity and light, which can degrade their efficacy over time. Excipients can create a protective matrix around the API, shielding it from these detrimental effects, and ensuring the longevity of the medication. Moreover, excipients can facilitate the dissolution and absorption of the API in the gastrointestinal tract, thereby enhancing bioavailability. For example, in formulations aimed at oral delivery, disintegrants are utilized to help the solid form of medication break down in the digestive system, allowing for faster absorption of the API into the bloodstream.
