Description

Soap-type cleaning composition

The present invention discloses a cleaning composition.

Cleansing compositions can be broadly classified into soap-type compositions, soap-free compositions, and semi-soap-type compositions. The soap type composition is obtained by neutralizing fatty acids with an alkali agent, while the soap-free type composition contains a weakly acidic synthetic surfactant, and the semi-soap type composition is obtained by mixing a soap type composition and a synthetic surfactant. . Among them, the known soap-type cleaning composition can form rich foam during cleaning, and has advantages such as excellent cleaning performance.

However, in a soap-type cleaning system obtained by neutralizing fatty acids, when such a system contains a high content of fat-soluble ingredients such as cream or oil, there will be a problem that the fat-soluble ingredients will act as a defoamer. The foaming is interrupted, resulting in a slippery feeling during rinsing. The reason is as follows: because there is a high content of fat-soluble components in the system, a material called scum will be produced, so there will be a fresh feeling when cleaning, and this material is composed of the carboxyl group (COO- ) Combined with divalent metal ions (magnesium or potassium) in the water. In the case of a soap-type cleaning system with a large amount of scum, it is difficult to stabilize the high content of fat through a formula that can neutralize fatty acids Soluble ingredients. In other words, in a soap-type cleaning system containing a high content of fat-soluble ingredients, it is impossible to form scum to prepare a formula containing a high content of fat-soluble ingredients to provide a fresh feeling during cleaning. This freshness is due to The slippery feeling caused by the fat-soluble component itself.

Therefore, in the case of conventional detergents containing high content of fat-soluble ingredients, a system has been used, which uses surfactants without carboxyl (COO-) groups as the base for emulsification. , And another cleaning composition based on related documents has been disclosed in Korean Patent Publication No. 10-0760973.

Hereinafter, the present invention will be described in detail with reference to examples. However, those skilled in the art will understand that the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[Example]

Prepare the facial cleansing composition according to Table 1 below, and then compare the foaming ability, defoaming ability of the facial cleansing composition, and the freshness of cleansing according to the following test methods.

In particular, the facial cleansing composition can be obtained according to a conventional method, and the conventional method includes: in a blender at 300-500 rpm, cross-linked with acrylate/C10-C30 alkanol acrylate cross-linked polymer And fatty acids, and emulsify high-content oil, cream or wax.

The results showed that in the soap-type cleaning system, Comparative Example 3, which did not add acrylate/C10-C30 alkanol acrylate cross-linked polymer, could not form a formula different from other compositions. Therefore, it can be seen that the acrylate/C10-C30 alkanol acrylate cross-linked polymer can stabilize the emulsion system in the soap-type cleaning system.

[Test Example 1] Foaming ability

Determination of foaming ability: 250ml of 1% facial cleansing composition is formed at a temperature of 25-30°C, and a SITA instrument is used to stir 10 times at 800 revolutions per minute, each time for 20 seconds, and the final stirring After the end of (the 10th time), the foam height was measured, and the results are shown in Table 2 below.

The results show that the addition of acrylate/C10-C30 alkyl acrylate cross-linked polymer to a soap-type cleaning system containing a high content of fat-soluble ingredients has the same foaming ability as conventional anionic surfactants (Comparative Example 1 ) And the cleansing composition (Comparative Example 2) that does not contain fat-soluble components have the same foaming ability. In particular, Example 1 exhibited remarkably high foaming ability.

[Test Example 2] Defoaming ability during cleaning

Measure the defoaming ability during washing: Take 5 panels for the sensory test exercise of the facial cleanser, which is expressed as the number of washing hands until the foam disappears during the washing period. In particular, take out 1g of each facial cleansing composition obtained in the above examples by hand, use 0.2-0.3g of tap water to make it foam 15 times with both hands, then rinse the hands with running tap water, and measure the disappearance of the foam Point in time. The results of the number of times of washing hands are shown in Table 3 below.

The results show that the addition of acrylate/C10-C30 alkyl acrylate cross-linked polymer to a soap-type cleaning system containing a high content of fat-soluble ingredients can defoam significantly and quickly even in contact with water, thereby achieving rapid cleaning efficacy. In addition, its effect is significantly higher than that of the conventional anionic surfactant composition of Comparative Example 1 without the addition of acrylate/C10-C30 alkyl acrylate cross-linked polymer.

[Test Example 3] Freshness during washing

To measure the freshness during washing: Take 5 panels to perform a sensory test exercise for the facial cleanser, and after testing the feeling of use, it is expressed by evaluating the freshness during washing. Especially, take out 1g by hand For each facial cleansing composition obtained in the above examples, use 0.2-0.3g of tap water to foam 15 times with both hands, then rinse the hands with running tap water, and measure the freshness (ie Refreshing feeling). The results of the degree of freshness are shown in Table 4 below, and the freshness is evaluated on a scale of 1 (weak freshness) to 15 (strong freshness).

The results show that the addition of acrylate/C10-C30 alkyl acrylate cross-linked polymer to a soap-type cleaning system containing a high content of fat-soluble ingredients is as fresh as a composition containing no fat-soluble ingredients (Comparative Example 2) The freshness is comparable. In addition, its effect is significantly higher than that of the conventional anionic surfactant composition of Comparative Example 1 without the addition of acrylate/C10-C30 alkyl acrylate cross-linked polymer.

Although representative embodiments of the present invention have been shown and described, those skilled in the art can understand that various forms and details can be made without departing from the scope of disclosure defined by the scope of the attached patent application. Change. Therefore, the scope of the present invention is meant to include all implementation aspects falling within the spirit and scope of the appended patent application.
