Description

  The present invention relates to a fragrance composition for an automatic dishwashing agent comprising fragrance components having different vapor pressures.

  In the cleaning composition, various fragrance components are used for masking and scenting the original odor of the cleaning composition, and for deodorizing and scenting the cleaning composition. In particular, deodorizing the object after washing, or leaving a desirable scent on the object (hereinafter referred to as residual fragrance) is an important factor.

  For example, as described in Non-Patent Document 1 and Non-Patent Document 2, the fragrance component is a top note (relatively high vapor pressure) or base note (relatively low vapor) due to a difference in volatilization speed, that is, vapor pressure. Pressure) and middle notes (between the two), and these are mixed and used in a balanced ratio according to the purpose. In general, it is expected that a perfume component used in a cleaning composition imparts sufficient deodorizing performance and fragrance performance to an object during or after cleaning. Therefore, it has been necessary to increase the perfume rate in the cleaning composition. However, if the perfume rate is simply increased, the scent of the cleaning composition itself becomes too strong and may cause discomfort.

In particular, for fragrances that are sensitive to odors that are attached to people, such as tableware and cooking utensils, and are blended in cleaning agents used in automatic dishwashers used in closed spaces, The scenting (residual property) performance of the object is not so important. Rather, performance that reduces these odors against steam generated during operation and generation of food odors in the storage after operation is desired. Therefore, a cleaning composition for an automatic dishwasher has been proposed which contains a specific amount of an oxygen bleach and suppresses the content of a fragrance (see Patent Document 1). In addition, a detergent composition for an automatic dishwasher that uses an oxygen-based bleach, a bleach activator, and a plant water extract to suppress the growth of bacteria remaining in the cabinet and to reduce unpleasant odors. Has been proposed (see Patent Document 2).
