Question
When using new cosmetic containers purchased from a store, such as from Daiso, is it necessary to clean them before filling?
Specifically for squeeze tubes with small openings, I am concerned that water might get trapped after washing, leading to bacterial growth. What is the recommended method for cleaning these containers, particularly squeeze tubes, to ensure they are safe to use?

Subject: Cleaning Cosmetic Containers
Based on the discussion, here's a summary of how to clean containers for homemade cosmetics, especially new ones purchased from a store:
- General Method for New Containers: The primary recommendation is to wash the containers thoroughly with clean water and then dry them completely. The key is to ensure no moisture remains, as bacteria need water to grow.
- Different Container Types:
- Jars and Pump Bottles: Washing with water and drying should be straightforward.
- Squeeze Tubes: You raised a valid concern about water potentially getting trapped in squeeze tubes due to the small opening. While the Staff didn't have a specific method for cleaning these, ensuring complete drying is crucial. You might need to find ways to help air circulate inside to help them dry fully.
- Additional Sterilization Methods (Use with Caution for Plastics):
- Boiling: Boiling is effective for sterilization but can damage certain types of plastic (like PET or PLA). HDPE is more resistant. This method is often discussed in the context of cleaning used containers with residues. For new containers, simple washing and drying is usually suggested.
- Alcohol (70%): Spraying the inside of plastic containers with 70% alcohol and letting it evaporate completely is another method mentioned, particularly if boiling isn't suitable for the plastic type. This can help sterilize.
- Recommendation for New Plastic Containers from a Store (like Daiso):
- The simplest approach, as suggested by the Staff, is thorough washing with water followed by complete drying.
- If you want extra assurance, especially for tubes where drying is difficult, you could consider using 70% alcohol spray, ensuring it dries completely before filling. Be cautious with boiling unless you are certain the plastic type can withstand it.
Ultimately, ensuring the container is completely dry is the most emphasized point for preventing bacterial growth when using new containers.
