Titanium Dioxide Price-How To Add Titanium Dioxide In Sunscreen
Titanium dioxide is a common ingredient in sunscreen because of its excellent UV-blocking properties and its ability to provide a physical barrier against the sun’s harmful rays. Here’s a general guide on how to add titanium dioxide to sunscreen, but please note that manufacturing cosmetics requires precision and adherence to safety regulations:
### Materials Needed:
– Titanium dioxide powder (nano or non-nano, depending on the desired effect and regulatory approval)
– Sunscreen base or carrier (such as a cream or lotion)
– A dispersing tool (like a mortar and pestle or a high-speed disperser)
– A clean, sterile environment to work in
– Protective gear (gloves, mask, etc.)
– Analytical balance for precise measurement
### Steps:
1. **Calculate the Desired Concentration**: Determine the percentage of titanium dioxide you want in your sunscreen. The concentration typically ranges from 2% to 25%, with 5-10% being common for sunscreens.
2. **Prepare the Work Area**: Clean your workspace and ensure it is free from contaminants. Sanitize all equipment that will come into contact with the sunscreen.
3. **Measure Titanium Dioxide**: Using an analytical balance, accurately measure the required amount of titanium dioxide. It’s important to be precise with the measurements to ensure the sunscreen’s effectiveness.
4. **Disperse Titanium Dioxide**: Add the titanium dioxide to a small amount of the sunscreen base. If you’re using a mortar and pestle, grind the mixture to ensure the particles are well-dispersed. If you have access to a high-speed disperser, use it according to the manufacturer’s instructions for optimal dispersion.
5. **Mix Thoroughly**: Once the titanium dioxide is well-dispersed in the small batch of the base, gradually mix it into the larger batch of the sunscreen base. This can be done with a spatula or a high-speed mixer, depending on the viscosity of the base.
6. **Check for Clumping**: Ensure that there are no clumps or aggregates of titanium dioxide in the sunscreen. Clumping can reduce the sunscreen’s effectiveness and may also cause skin irritation.
7. **Test the Sunscreen**: Before using the sunscreen on a large scale, conduct stability and safety tests. This may include checking for separation, changes in color or consistency, and skin irritation tests.
8. **Comply with Regulations**: Ensure that your sunscreen formula complies with local regulations regarding the use of titanium dioxide in cosmetics. This includes particle size restrictions and labeling requirements.
9. **Packaging**: Once the sunscreen is properly mixed and tested, package it in sterile containers that protect the product from light and air, which can affect the stability of the sunscreen.
10. **Labeling**: Label the sunscreen with all the necessary information, including the percentage of titanium dioxide, expiration date, and any other relevant information required by law.
Remember, when handling titanium dioxide and other raw materials for cosmetic products, it’s important to wear appropriate personal protective equipment (PPE) such as gloves and masks to avoid inhalation and skin contact.
If you are not experienced in cosmetic manufacturing, it’s advisable to consult with a cosmetic chemist or a professional manufacturer to ensure that your sunscreen is safe and effective.
