A stabilizer is a vital additive used across various industries to preserve the integrity and longevity of products. It works by preventing undesirable changes like separation, degradation, or chemical reactions, ensuring that products maintain their intended quality. In plastics, stabilizers guard against damage from heat, light, or oxygen, preserving durability and flexibility. In food, they keep ingredients uniformly mixed, enhancing texture and consistency. Cosmetics benefit from stabilizers by maintaining emulsions and extending shelf life. Essential in both industrial and consumer products, stabilizers ensure that items remain effective, safe, and aesthetically pleasing throughout their use.
