Abstract: An edible composition comprising a coated conditioner that contains a hydrophobization agent and inorganic particles is provided. When incorporated into an edible composition (such as a powdered pharmaceutical or food product), the coated conditioners inhibit caking and promote the free flow of powder. Suitable hydrophobization agents include food-grade fatty acids, food-grade oils, food-grade waxes, and food-grade gums, while suitable inorganic particles are selected from the group consisting of silica, silicates, calcium carbonates, phosphates, and clays. The coated conditioner is particularly suitable for use in pharmaceutical preparations, such as acetaminophen.
