  • Publication number: 20080207481
    Abstract: Conventional perfumed consumer products are characterized by a uniform odor throughout the entire product. Consumer products are described that comprise at least two differently smelling perfume oils which are not evenly distributed in the product in proportion to one another. This allows the consumer to produce, using one and the same product, a variety of odors during applications and overcome the monotony of the olfactory experience associated with conventional perfumed consumer products.
