Softening agents are substances added to materials, particularly in textiles and plastics, to enhance their flexibility and reduce stiffness. They work by creating a lubricating effect between the fibers or polymer chains, making the material easier to handle and more comfortable to use. Common examples include fabric softeners for laundry and plasticizers for various plastic products. In the context of personal care, softening agents are often found in moisturizers and conditioners, where they help to improve the texture and feel of skin and hair. These agents can also aid in reducing friction, making products more effective and pleasant to use.
