1. What Are Chemical Additives? Definition: Chemical additives are substances intentionally added to food, pharmaceuticals, cosmetics, or industrial products to enhance performance, extend shelf life, improve appearance, or modify taste. Common Types: Food: Preservatives (e.g., potassium sorbate), colorants (e.g., tartrazine), sweeteners (e.g., aspartame). Consumer Goods: Preservatives in cosmetics (e.g., phenoxyethanol), plasticizers in p
The Function of DMAA
News 2025-04-07 267
DMAA (1,3-Dimethylamylamine) functions primarily as a central nervous system (CNS) stimulant. Central Nervous System Stimulation: DMAA acts on the CNS to increase alertness, energy, and focus. It mimics the effects of adrenaline by stimulating α and β adrenergic receptors, leading to heightened arousal and reduced fatigue. Performance Enhancement: Historically marketed in pre-workout supplements and athletic performance products, DMAA was tou
What Are the Most Common Food Additives?

Difference Between APIs and Pharmaceutical Materials
News 2025-04-07 242
The pharmaceutical manufacturing process involves various substances that play distinct roles in drug formulation. Two critical components are Active Pharmaceutical Ingredients (APIs) and Pharmaceutical Materials (excipients). While both are essential for drug production, they serve fundamentally different purposes. This article clarifies their differences in definition, function, regulation, and application. 1. Definition and Core Function Acti
Electronic Structure Regulate Adsorption of CO₂RR
News 2025-04-07 413
The electrochemical reduction of carbon dioxide (CO₂) to valuable chemicals and fuels, known as CO₂RR (CO₂ Reduction Reaction), holds immense promise for mitigating climate change and achieving sustainable energy solutions. Central to this process is the adsorption of reaction intermediates on catalyst surfaces, which profoundly influences the reaction pathway, efficiency, and selectivity. A critical question arises: does the electronic structure
