Low molecular weight acetal, alcohol, O-acylated alcohol and ester compounds are identified that block the odor of specific carboxylic acids especially propionic acid, butyric acid, isovaleric acid 3-methyl-2-hexenoic acid and hexanoic acid. These compounds exhibit surprisingly high odor blocking properties and are therefore useful additives to compositions such as: a) personal care products including underarm deodorant and antiperspirant, hair shampoo and conditioner, toilet soap, and skin lotion; b) fabric care products including laundry detergents, fabric conditioners, and fabric fresheners; c) pet care products including deodorant, shampoo, conditioner, and d) home care products including air fresheners, carpet fresheners, surface cleaners and hand wash dish detergent.
识别出低分子量的
缩醛、醇、O-酰化醇和
酯类化合物,可以阻止特定
羧酸的气味,特别是
丙酸、
丁酸、
异戊酸、
3-甲基-2-己烯酸和
己酸。这些化合物表现出惊人的高气味阻断性能,因此可作为以下配方的有用添加剂:a)个人护理产品,包括腋下除臭剂和止汗剂、洗发
水和护发素、香皂和皮肤乳液;b)织物护理产品,包括洗衣液、织物柔顺剂和织物清新剂;c)宠物护理产品,包括除臭剂、洗发
水、护发素;d)家居护理产品,包括空气清新剂、地毯清新剂、表面清洁剂和手洗碗清洁剂。
