Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition in which even a fragrance composition containing less limonene is uniformly dissolved in the detergent composition and has good stability.

[0002]

2. Description of the Related Art Generally, household detergents such as laundry detergents, dish detergents, household detergents, and body cleaning agents such as shampoos and soaps, which are generally used at home, have various types suitable for the purpose and product image. Fragrance-like fragrances have been proposed and perfumed.
These fragrances are composed of a single substance or a plurality of organic compounds, and the fragrance material as an element thereof includes those derived from chemical synthesis and naturally derived substances such as plant essential oils. In the present invention, for the sake of explanation, a single fragrance compound and a fragrant natural essential oil generally known as a fragrance component are referred to as a fragrance, and a prepared fragrance obtained by combining these is called a fragrance composition.

The liquid detergent composition used at home as described above contains a surfactant, a solvent such as ethanol, a fragrance composition, and other optional components depending on the intended use and purpose.
It is common that the balance contains water. It is extremely important that the liquid detergent composition is stable from the time of preparation to long-term storage so as not to impair the performance such as detergency and the commercial value, and it is of course necessary to consider a formulation that does not cause phase separation. For some commercial products, a substantially transparent liquid detergent composition having no turbidity is desired. Perfume compositions can also contribute to their stability, so in addition to palatability, stability in liquid detergent compositions also needs to be considered.

By the way, since the citrus-like one is preferred as the perfume composition for the conventional dishwashing detergent and the stability is also good, limonene or a natural orange essential oil containing it as a main component is preferred. A fragrance composition (amount of limonene: about 85 to 100% by weight) containing a large amount of the like is used. However, if the blending amount of limonene in the fragrance composition is reduced to less than 85% by weight, there is a problem that solubility in a liquid detergent during production and storage stability deteriorate. As a cause, compatibility between the fragrance composition and the cleaning component is considered, and especially when the surfactant composition in the cleaning composition is large, the problems of solubility and storage stability due to the addition of the fragrance composition become remarkable. Become. On the other hand, in order to obtain a fragrance composition having a scent other than citrus, it is necessary to set the amount of limonene to be 85% by weight or less and to mix a non-citrus fragrance such as fruit, herb, green or mint. Therefore, by using a fragrance composition containing less limonene, a liquid detergent composition having excellent solubility during production and excellent storage stability, in particular, a liquid detergent composition with a scent of a non-citrus scent is obtained. It was difficult.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid detergent composition which is evenly dissolved in a detergent composition and has good stability even in a perfume composition having a low limonene content. is there.
