2. Plasticizers Many types of plastics are rigid in their natural state. To enhance flexibility and workability, plasticizers are added. Phthalates are commonly used plasticizers that soften plastics like polyvinyl chloride (PVC) to produce a more flexible material suitable for applications such as pipes, toys, and flooring. However, due to health concerns regarding certain plasticizers, there is an increasing demand for safer alternatives, such as bio-based plasticizers.
4. Wound Healing Pentoxifylline has been investigated for its role in promoting wound healing, especially in patients with chronic ulcers or diabetic foot complications. By improving blood flow to affected areas, the drug may accelerate the healing process and reduce the risk of infections.
Another important application of chemical dosing is coagulation and flocculation. In this process, coagulants like aluminum sulfate or ferric chloride are added to the water. These chemicals bind with suspended particles, forming larger aggregates or flocs that can be easily removed during sedimentation or filtration. This step is particularly important in treating water from surface sources, which often contains high levels of turbidity due to silt, clay, and organic matter.

Moreover, the use of antioxidant additives contributes to sustainability efforts in the plastics industry. By extending the service life of plastic products, these additives help reduce waste and encourage recycling. Longer-lasting materials mean that products do not need to be replaced as frequently, which can lead to lower consumption of raw materials and energy.
