In life, there is always a period of time to sterilize several glass bottles. Making your own skin care products is a great way to reduce disposable packaging and customized products. In addition, refillable skin care products can be used every day, but you need to ensure that all containers are safely disinfected before refilling!
Our simple 5-step guide to sterilizing glass bottles will give you confidence to reduce pollution and refuel!
When the old container is reused, the possibility of contaminating the product will increase! Before refilling, be sure to sterilize the glass bottle to prevent contamination. We provide you with a concise guideline below-but the wise choice is up to you, because you will have to deal with high temperatures and fragile glass. If you are unsure, use a brand new sterilized container.
What do you need:
70% isopropanol (preferably used in a spray bottle)
Empty glass dropper bottle
Step 1: Clean and soak
Make sure your bottle is empty. Oil-containing products (such as oil-based serum) cannot fall in and should be placed in the trash can.
After the bottle is emptied, rinse it quickly to rinse off any remaining product. To help release all labels and ensure that the container is clean, soak in soapy water overnight.
Step 2: Rinse, repeat
Remove label. Depending on how long you soak the bottle, this may require some elbow grease! Spray with 70% isopropyl alcohol to remove any stickiness.
After removing the label, rinse twice with warm water to remove the remaining soap from the bottle.
Step 3: Cook for ten minutes
Be careful not to burn yourself (the glass container will become very hot), use tongs to put the glass bottle in boiling water. Cook for ten minutes.
After ten minutes, remove the bottle with tongs. They will be very hot, so just place them on the surface to cool them down before processing.
Step 4: Rinse in 70% isopropyl alcohol
After the glass bottle is completely cooled, please rinse it with 70% isopropanol.
Completely submerge the glass bottle for disinfection.
If you are confident that you can clean the entire inner surface of the bottle, pour enough isopropyl alcohol into each bottle for cleaning. Just squander it!
Step 5: Air dry
Place fresh paper towels on a clean surface. Place each bottle upside down on a paper towel and let it drip dry.
You need to wait for the bottle to dry completely before refilling.
Be sure to wait for all alcohol and all residual water to completely evaporate before filling or reusing it. The best option is not to rush to let them dry overnight or 24 hours.
Tips for cleaning glasses
Since you cannot boil the plastic parts of the glass dropper, it is difficult to ensure proper disinfection. Generally speaking, unless you use the dropper for other purposes (other uses other than cosmetics), we recommend that you do not reuse the dropper. Remember that contaminated products are bad for your health and pose a higher direct risk to you-so if you are not sure, don't risk it!
However, depending on the style of the dropper, you may be able to remove the glass pipette from the plastic dropper tip. Simply pull and shake the pipette to release it from the cap.
Same as the above guide: Put the glass pipette and plastic tip into the bottle and soak overnight.
After you have finished soaking, you can use cotton swabs and soapy water to clean the inside of the pipette and dropper.
Repeat this step twice with water to rinse.
We do not recommend boiling small glass pipettes because they may break.
Instead, after rinsing off all the soapy water, immerse the plastic tip and glass pipette in 70% isopropanol. Remove and air dry completely.
Due to the design of the dropper, it is difficult to tell whether it has been completely air-dried, putting you at risk of contaminating the product. If in doubt, use a new dropper.
If you are sure that everything is dry, just put the pipette back into the plastic dropper and refill it!
