Blackberry Titanium Dioxide is a popular choice for homemade soap projects as it is a trusted cosmetic ingredient. Sourced from leading soap maker Brambllebry. this pure water-soluble white pigment is known for its ability to produce vibrant and rich colors while also providing opacity. blendability and resistance to discoloration - even in high alcohol products. To avoid clumping. be sure to properly disperse it in oil or water before use. While safe for the skin. precautions should be taken to avoid inhalation. such as wearing a mask during treatment.

Polypropylene (PP) is a thermoplastic "addition polymer" known for its versatility. Its physical properties include a melting point of 130-171°C, making it useful in applications requiring heat resistance. PP is lightweight, has a density of 0.855-0.946 g/cm³, which contributes to its popularity in packaging and automotive components. It exhibits excellent chemical resistance to bases, acids, and solvents, enhancing its suitability for containers and pipework. Additionally, PP has good fatigue resistance, meaning it withstands repeated flexing without failure. It's also semi-rigid, offering a good balance between plastic toughness and stiffness. However, its resistance to UV radiation is relatively poor unless modified or stabilized, affecting its outdoor application longevity.

To determine the BTU content for 12 pounds of polypropylene, it's crucial to know the specific energy content of polypropylene, which is typically around 19,900 BTU per pound. This value can vary slightly depending on the specific type and grade of polypropylene. By multiplying the specific energy content by the weight (12 pounds in this case), we get the total BTU content. So, \(19,900 \, \text{BTU/lb} \times 12 \, \text{lb} = 238,800 \, \text{BTU}\). This calculation provides an estimate of the energy that could be released by completely burning 12 pounds of polypropylene, useful in applications like waste-to-energy conversion.
