Measuring Tools for Beginners

Thank you for the helpful advice from touchzhakornxx! That's very useful information.

Here is some additional information regarding your questions:

• Digital Scale: As touchzhakornxx recommended, a digital scale with decimal precision is crucial for cosmetic formulation. Many ingredients, especially active ones, are measured by weight for accuracy according to the formula.
• Beakers vs. Measuring Cylinders:
  • Beakers: Have a wide opening and volume markings on the side, but the scale is less precise than a measuring cylinder. They are suitable for mixing ingredients, heating, or approximate liquid measurements where high accuracy isn't required.
  • Measuring Cylinders: Are tall and narrow with a much finer scale, making them suitable for accurately measuring specific volumes of liquids.
  • In Summary: If you need precise liquid volume measurement, use a measuring cylinder. However, generally, weighing ingredients with a digital scale provides higher accuracy and is more commonly used in cosmetic formulation.

Reusing Packaging Containers

• Reusing Containers: Yes, you can reuse containers if they are still in good condition and, importantly, properly cleaned and sterilized before refilling.
• Sterilizing Plastic Pump Bottles:
  1. Thoroughly wash away any old product residue from both the bottle and the pump head using dish soap and a brush to clean all parts.
  2. Rinse with clean water multiple times to ensure no soap or residue remains.
  3. Spray the inside of the bottle and the pump components with sterilizing alcohol (e.g., 70% isopropyl alcohol) or use a sterilizing solution suitable for plastic materials.
  4. Allow the container and all parts to air dry completely in a clean, dust-free area before filling with a new product. (Avoid using high heat, like boiling, to sterilize, as some plastics may be damaged.)

Hope this information is helpful for you to start making your products!
