Plant waxes are natural substances produced by various plants to protect their surfaces. These waxes are primarily made of long-chain fatty acids and alcohols, forming a waterproof layer that helps prevent water loss and shields against environmental stressors like pests and UV radiation. Commonly found on leaves, fruits, and stems, plant waxes play a crucial role in maintaining plant health. They can also be harvested for various uses, including cosmetics, food coatings, and industrial applications. Examples of plant waxes include carnauba wax from the carnauba palm and beeswax, which is produced by honeybees.
