A disposable absorbent article is provided with a odor control powder which is unscented in a dry state and releases a burst of fragrance when wetted, such as by human waste. The powder contains a relatively small amount of fragrance oil, such as 0.5% to 4% by weight, to prevent skin irritation to the wearer. The small amount of fragrance oil is microencapsulated in a starch which constitutes from about 50% to 90%, and preferably about 70%, of the total weight of the particles. Sodium bicarbonate is also included in the particulate odor control material in an amount ranging from 5.0% to 45%, and preferably about 25% by weight, of the total weight of the particles. The sodium bicarbonate promotes skin wellness by controlling the pH levels of the fragrance oil, starch and human waste. A small amount of flow agent is also contained in the particulate odor control material.
