A disposable absorbent article is provided with an 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. |
