JP6565363B2 - Cleaning composition for pump former - Google Patents

Description

  The present invention relates to a cleaning composition for a pump former that is discharged in a foam form by a pump former.

  When using a foaming cleaning material, it is usually expected to have an effect of improving the cleaning power by increasing the retention in the parts to be cleaned by foaming with a palm or a foaming net. A buffering effect is produced, and an effect of reducing a physical load on the portion to be cleaned can be expected. However, the work of foaming at the time of use becomes a burden on the user, and depending on the degree of foaming, the effect of improving the cleaning power and the effect of reducing the physical load may not be sufficiently exhibited.

  Therefore, pump formers that can discharge the cleaning agent in the form of bubbles have appeared. The pump former has a porous film inside, and is discharged in the form of bubbles by being mixed with air when the cleaning material passes through the porous film. Accordingly, since the pump former needs to pass through the porous film, clogging may occur depending on the cleaning material, and uniform bubbles may not be discharged.

Therefore, a composition suitable for a pump former has been proposed. For example, Patent Document 1 proposes a liquid detergent article in which a surfactant such as alkyl glucoside, ethanol, and citric acid are combined. Patent Document 2 proposes a liquid detergent composition in which alkyl glyceryl ether, alkyl glucoside, alkyl benzene sulfonate, and magnesium are combined.
However, these detergent compositions do not have sufficient foam elasticity.

Then, the composition which combined glycol and sugar with the fatty acid salt excellent in foam quality is proposed. For example, Patent Document 3 proposes a cleaning agent in which a nonionic surfactant such as a fatty acid salt, an organic acid salt, or a stearic acid pentaglyceride is combined. Patent Document 4 proposes a detergent composition in which an anionic surfactant such as a fatty acid salt, glycosyl trehalose, and a hydrolyzed plant protein are combined. Patent Document 5 proposes a liquid detergent composition in which a fatty acid salt, an amphoteric surfactant, a polyoxyethylene sorbitan fatty acid ester, an alkylalkanol-type nonionic surfactant, and the like are combined. Further, Patent Document 6 proposes a detergent composition in which a fatty acid salt such as potassium myristate and a glycol are combined.
However, when these compositions are used from the top of makeup, there are problems that the persistence of the foam is insufficient or that a feeling of tension is generated after washing.
