Description

Liquid detergent composition {LIQUID DETERGENT COMPOSITION}

The present invention relates to a liquid detergent composition. Specifically, the present invention relates to liquid detergent compositions suitable for use in filling into foamer containers.

Good foam quality, since cleansers such as body washes and facial washes are commonly used after foaming and prevent the friction caused by direct contact of the skin by the fingers by washing with foam. A cleanser with is required. In recent years, in order to easily obtain a good quality foam, a pump former type cleanser that discharges a cleaning agent into a foam by being discharged with air from a fine hole has been popularized. From this point of view, the focus is on the care of the skin during washing and there is a high interest in cleansing power. So far, cleansers with a strong cleansing force have been recognized as good, but if the cleansing force is too high, the skin is degreased with makeup cosmetics such as lipstick and foundation, and in some cases skin roughness may be caused. Therefore, in recent years, there is a need for a cleanser that has a cleansing force capable of removing makeup cosmetics and can further provide a moist feeling after washing.

From this background, a detergent composition containing N-acylglutamic acid anionic surfactant, betaine type amphoteric surfactant, higher fatty acid soap, and polyhydric alcohol, showing good foam quality and providing a moist feeling after washing This was proposed (JP-A-2012-97009). However, the detergent composition of JP-A-2012-97009 has insufficient foam quality such as elasticity and persistence of foam.

In addition, JP-A-2013-155143 proposed a detergent composition containing amphoteric surfactant, cationic cellulose, N-acylamino acid-based anionic surfactant, and nonionic surfactant and showing good foam quality.

However, the detergent composition of JP-A-2006-183039 has insufficient foam quality such as elasticity and persistence of foam.

In addition, the detergent composition of JP-A-2013-155143 causes clogging problems when used with pump formers because the composition contains cationic cellulose.

Accordingly, the problem to be solved by the present invention is to provide a liquid detergent composition that has a cleansing force capable of removing makeup cosmetics, provides a moist feeling after washing, does not cause clogging, and provides elastic foam that persists even during washing. Is to do.

As a result of continuous research to solve the above problems, the present inventor has a cleansing force capable of removing makeup cosmetics by properly configuring the composition of the present application, provides a moist feeling after washing, and does not cause clogging, even during washing A detergent composition that provides a lasting elastic foam was invented.

When the gas-liquid interface is newly formed, component (b) excellent in dynamic surface tension is rapidly adsorbed from the inside of the water to the interface to stabilize the interface (FIG. 1). After component (b) adsorbs to the interface, component (a) later adsorbs to the interface, and the foam film is thickened by entanglement of the PEG chains, so that the elasticity and persistence of the foam are sharply enhanced (Fig. 2). When the added mole number of ethylene oxide was in the low molecular range, that is, when the added mole number of ethylene oxide was 80 moles or less, entanglement of the PEG chain did not occur as shown in FIG. 3, and the elasticity and persistence of the foam were insufficient. It turned out.

In addition, when [a + b + c] exceeds 30% by mass, not only is it not costly advantageous, but also the discharge performance from the pump former is deteriorated, and clogging may be caused. From this point, [a + b + c] is more preferably 25% by mass or less, and more preferably 20% by mass or less.

The mass ratio [a / b] of the content of component (a) to the content of component (b) is 1/3 to 40/1.
