What is the function of emollient oil in deodorant?

Emollient oil in deodorant serves to moisturize and soften the skin, helping to prevent irritation and dryness that can result from the application of other ingredients. It also enhances the overall texture of the product, making it smoother and easier to apply. Additionally, emollient oils can provide a barrier that helps to lock in moisture and improve the longevity of the deodorant's effects.
