Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a kitchen detergent composition, and more particularly to a detergent composition containing a specific surfactant and capable of safely washing not only dishes but also dish towels. [Prior Art and Problems] Conventionally, kitchen detergents are mainly used for washing dishes by hand, so they have compositions that are less likely to cause roughness on hands. These are mainly formulated with a combination of amine oxide and higher alcohol/ether sulfate, and are less irritating to hands.
In addition, it has high cleaning power and foams abundantly, so it has become the mainstream of kitchen detergents. In addition, α-olefin sulfonate is alkylbenzene sulfonate, higher alcohol sulfate,
In recent years, its development has progressed as a surfactant used in kitchen detergents, along with higher alcohol ethoxy sulfates. That is, due to recent advances in the petrochemical industry, α-olefin sulfonate has been developed for application due to the cost advantage of its raw material olefin and its performance as a surfactant. However, in kitchen cleaners using α-olefin sulfonate or amine oxide,
Although there is no particular problem in cleaning dishes with oily stains, there is a serious drawback in that a dish towel gives off a strange odor when washed. This odor is further aggravated by drying clothes outdoors for a long time during the day. Dish towels are used to clean up washed dishes and play a variety of other auxiliary roles related to eating. Smells in the kitchen, not only strange odors, but even aromas, are something to be especially careful about as they affect the taste of food, and countermeasures have been desired. Of course, this problem can be easily solved by using a detergent that does not contain α-olefin sulfonate or amine oxide, but it is also troublesome for consumers to use another detergent for that purpose.
It is naturally preferable to wash dishes and dishcloths with one detergent. [Means for Solving the Problems] As a result of intensive studies by the present inventors to solve these problems, it was found that even with cleaning agents having the above composition, the addition of specific compounds significantly generates off-odor. The present invention was completed based on the discovery that this can be suppressed. That is, the present invention provides a kitchen cleaning composition containing an α-olefin sulfonate having an average of 12 to 18 carbon atoms or a mono-long chain alkylamine oxide having an average of 10 to 16 alkyl groups, A kitchen cleaner composition characterized by containing at least one compound selected from the group consisting of aliphatic aldehydros having 8 to 10 carbon atoms, aromatic aldehydes having 7 to 15 carbon atoms, and lower alkyl esters of anthranilic acid. It is something that provides something. The average of 12 to 18 carbon atoms used in the present invention is 1
The α-olefin sulfonate contained in the molecule is obtained by sulfonating olefin using a conventional continuous thin film sulfonation device, followed by neutralization and hydrolysis. In this case, the raw material olefin is a C ₁₂ to _{C 18} α-olefin obtained by a wax cracking method, a polymerization method using the Ziegler method, or an improved method thereof:
_C12 - _C18 inner olefins: _C12 - _C18 vinylidene olefins: and mixtures thereof are used. Also used as salts are alkali metal salts, alkaline earth metal salts, especially magnesium salts and mixtures thereof. In addition, the mono-long chain alkylamine oxide has the following formula (1)
