Autoclavable polypropylene (PP) plastics are designed to withstand high temperatures and pressures during the sterilization process in an autoclave. With a melting point around 130°C to 171°C, PP can endure the autoclaving temperatures typically between 121°C and 134°C. Its key properties include excellent chemical resistance, making it suitable for various laboratory and medical applications where sterilization is a must. However, it's important to note that prolonged or repeated autoclaving cycles may affect the structural integrity and mechanical properties of polypropylene. Thus, it's advisable to assess the lifespan and durability of PP items in conditions where they are frequently autoclaved. Overall, autoclavable polypropylene offers a cost-effective and durable solution for applications requiring sterilization, provided its limitations are taken into account.

Titanium dioxide is commonly used in facial wash and other skincare products for several reasons:

1. Sun Protection: Titanium dioxide is a physical sunscreen which helps to protect the skin from harmful UVA and UVB rays.

2. Gentleness: It is less likely to cause skin irritation, making it a good option for people with sensitive skin.

3. Color: Titanium dioxide is a white pigment, it is used to provide whiteness and opacity to products such as facial wash.

4. Coverage: In certain products, titanium dioxide can provide some degree of coverage hiding minor skin imperfections.

5. Stability: Titanium dioxide is highly stable and helps to increase the shelf life of cosmetic products.

6. Antibacterial Properties: Some studies suggest that titanium dioxide has antibacterial properties which may be beneficial in products formulated for acne-prone skin.

However, note that the usage of titanium dioxide has been a topic of controversy because of potential risks related to nano particles. Modern cosmetic products normally use the non-nano form to prevent any potential risks.
