PROBLEM TO BE SOLVED: A main factor in bad breath is a malodorous substance produced by periodontal disease-causing bacteria. Bad breath cannot be eliminated even during periodontal disease treatment. In the conventional oral intake of lactic acid bacteria, most of the lactic acid bacteria in the oral cavity are washed away by the stomach by swallowing beverages or swallowing saliva and die. There is a demand for means for constantly replenishing oral cavity with lactic acid bacteria to reduce bad breath. SOLUTION: Lip balm consisting of whey of yogurt, edible oil, egg yolk lecithin and thickener such as starch, or lipstick consisting of fats and oils and live lyophilized lactic acid bacteria and starch or sugar is applied to lips. As a result, lactic acid bacteria are engrafted on the folds of the lips, and are moisturized by the oil film, and at the same time, they are partially isolated from oxygen in the air. Unlike the oral cavity, the lips are not washed by swallowing beverages or saliva, so that lactic acid bacteria can grow and survive, and licking the lips with the tongue replenishes the lactic acid bacteria into the oral cavity.【課題】口臭では主な要因は歯周病原因菌の産生する悪臭物質である。歯周病治療中も口臭を無くすことはできない。従来の乳酸菌口腔内摂取では、飲料の飲み込みや唾液の嚥下により口腔内の乳酸菌の殆んど胃に流されて死滅する。口腔内に常に乳酸菌を補充して口臭を軽減する手段が求められている。【解決手段】ヨーグルトの乳清と食用油と卵黄レシチンとデンプンなどの増粘剤からなるリップクリーム又は、油脂と色素と生きた凍結乾燥させた乳酸菌及びデンプンや糖からなる口紅を唇に塗布することで唇のヒダに乳酸菌が生着し更に油脂膜によって保湿されるとともに一部は空気中の酸素からも隔離される。唇は口腔内と異なり、飲料や唾液の嚥下による洗浄がなされないため乳酸菌の増殖と生着が可能となり、舌で唇を舐めることで口腔内への乳酸菌の補充がなされる。
