Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a detergent composition having excellent ream retention. [0002] As a detergent composition for cosmetics, N-
Acylglutamic acid and its salts have been widely used.
Its production method is known. In the case of liquid cleaners in winter,
Low temperature stability is important, especially when used in cold regions.
Is a factor that causes the final product to solidify during
Products that were initially transparent were clouded or initially uniform
It is necessary to minimize the separation of a product into two phases
No. [0003] In the case of a creamy detergent, particularly in the summer, especially in warm weather.
Considering local use, cream shape retention under high temperature
It is an important factor, which makes the final product soft during storage
Or so-called "who"
And water separation should be avoided as much as possible.
Absent. To solve these problems, Japanese Patent Application Laid-Open No. 6-49
481 specifies the degree of neutralization of acylglutamic acid.
Attempts to improve low temperature stability by
However, its low-temperature stability is still insufficient, and
There is no description about the shape retention, and
At this time, there was no improvement in the physical properties. Also,
In JP-A-10-121091, the dipeptide moiety is acidic.
An N-long chain acyl dipeptide salt composed of amino acids;
Detergent composition containing N-long-chain acyl acidic amino acid salt
Is excellent in hypoallergenicity, hard water resistance and usability
Although disclosed, the present inventor considered that
Insufficient thermal stability and high temperature cream retention
Was. In JP-A-2001-107078, a counter ion
Improve low-temperature stability by specifying equivalent ratio of salt
Although it was done, it was still insufficient. [0004] The present invention mainly relates to N
-Containing an acylglutamic acid or a salt thereof at normal temperature (15 to
25 ° C) liquid or gel detergent composition
Excellent in low-temperature stability or cream retention at high temperatures
It is an object of the present invention to provide a cleaning composition. [0005] The present inventors have set forth the above object.
As a result of intensive studies to solve the problem, the specific N-
Acylglutamic acid or a salt thereof, N-acyl-α and
And / or γ-diglutamic acid or a salt thereof, and free fat
By preparing a composition containing an acid or a salt thereof,
Liquid at room temperature (15 to 25 ° C)
In the case of, the freezing point is sufficiently low to ensure low-temperature stability.
Excellent, gelled at room temperature (15-25 ° C)
Has a sufficiently high crystallization point for excellent cream shape retention
That the present invention has been completed.
You. Hereinafter, the present invention will be described in detail.
I will tell. The component (A) of the cleaning composition of the present invention,
N-acylglutamic acid represented by the general formula (1) and
With respect to the optical activity of the amino acid portion of the salt of
Both body and DL body may be used. Included in N-substituted acyl groups
The alkyl group has 7 to 23 carbon atoms. The archi
When the number of carbon atoms in the radical is within this range, the cleaning agent of the present invention
The composition is liquid or gel at room temperature and has a good low temperature
It will have stability or cream retention. Also,
The above general formula, which is the component (B) of the cleaning composition of the present invention.
N-acyl-γ or α jig represented by (2) or (3)
For glutamic acid and its salts,
Regarding optical activity, use any of L-form, D-form and DL-form
May be. In the present invention, the component (B) is
Having an N-substituted acyl group in common with (A), and
(C) is also common with the N-substituted acyl group of component (A).
It has an alkylcarbonyl group. N-substitution of component (B)
An acyl group and an alkylcarbonyl group of the component (C)
When such, the low temperature stability of the detergent composition
Or those with mild shape-dependency of cream shape retention
The operation of adjusting the composition of the composition having the desired effect is
It will be easy. In the present invention, component (A),
Ratio of component (B) to total amount of (B) and (C)
Is 0.1 to 5% by mass. In the present invention, the components
(B) Equivalent effect in both α-form and γ-form
Therefore, a predetermined ratio is included in the component (B) as a whole.
I just need to be. If the content is less than 0.1% by mass, low-temperature stability and
If the ream shape retention is not sufficient and it is 5% by mass or more, low
The temperature stability and the shape retention of the cream are reduced rather
Or, it is disadvantageous in terms of cost such as raw material cost. Like
Or 0.1 to 3% by mass. [0008] Component (C) in the cleaning composition of the present invention
The ratio of free fatty acids and salts thereof is determined by the components (A), (B),
And 0.1 to 5% by mass based on the total amount of (C).
0.1% by mass or less, low temperature stability and cream shape retention
On the contrary, when it is 5% by mass or more, the freezing point is
It increases in proportion to its content, and conversely, the crystallization point
It is not preferable because it decreases in proportion to the amount. Preferably
0.1 to 3% by mass. The cleaning composition of the present invention impairs its effects.
