    Study Notes

    Household Chemicals

    • Many household products contain chemicals that can be harmful if not handled properly:
      • Cleaning products: bleach, ammonia, and quaternary ammonium compounds
      • Pesticides: insecticides, herbicides, and fungicides
      • Personal care products: soaps, detergents, and fragrances
    • Importance of reading labels and following instructions for use, storage, and disposal
    • Alternative: using natural or eco-friendly products to reduce chemical exposure

    Food Chemistry

    • Chemical reactions occur during food preparation and cooking:
      • Maillard reaction: browning reaction between amino acids and reducing sugars
      • Emulsification: mixing of oil and water using emulsifiers
      • Gelation: thickening of liquids using gelling agents
    • Food additives:
      • Preservatives: extend shelf life and prevent spoilage
      • Flavor enhancers: enhance taste and aroma
      • Colorants: add color to food products
    • Nutritional chemistry: understanding the chemical composition of nutrients and their effects on the body

    Pharmaceuticals

    • Medicinal chemistry: design, development, and synthesis of pharmaceuticals
    • Drug classification:
      • Analgesics: pain relief
      • Antibiotics: infection treatment
      • Vaccines: disease prevention
    • Pharmacokinetics: absorption, distribution, metabolism, and excretion of drugs in the body
    • Importance of proper medication use, dosage, and potential interactions

    Cosmetics

    • Chemical composition of cosmetics:
      • Skin care: moisturizers, sunscreens, and cleansers
      • Hair care: shampoos, conditioners, and dyes
      • Makeup: foundations, lip products, and eye products
    • Cosmetic chemistry:
      • Emulsions: mixtures of oil and water
      • Surfactants: reduce surface tension and improve spreadability
      • pH balance: maintaining skin and hair pH levels
    • Safety and regulation: ensuring the safety and efficacy of cosmetic products

    Environmental Impact

    • Chemical pollutants in the environment:
      • Air pollution: gases, particulate matter, and volatile organic compounds
      • Water pollution: industrial and agricultural chemicals
      • Soil pollution: heavy metals, pesticides, and industrial waste
    • Environmental chemistry:
      • Biodegradation: breakdown of organic matter
      • Bioaccumulation: accumulation of chemicals in organisms
      • Biomagnification: concentration of chemicals in food chains
    • Importance of sustainable practices and responsible chemical use to minimize environmental impact
