Description

  The present invention relates to a hard surface cleaning composition.

  A detergent composition for a hard surface such as a detergent composition for hand-washing dishwashing is required to have abundant foaming during washing and persistence of the foam during washing. This foamability / foam persistence is a very important physical property that correlates with the persistence of washing, and until now, the development of a cleaning agent excellent in foamability / foam persistence has been mainly performed. On the other hand, in recent years, it has been preferable to reduce the amount of water used for washing for the purpose of reducing the environmental burden and effectively using water resources, and it is desired to reduce the rinse water after washing with a hand-washing dishwashing detergent as much as possible.

  In order to improve foamability / foam persistence, it is generally known that addition of a water-soluble polymer is effective. For example, Patent Document 1 discloses a liquid hand-washing detergent composition that uses a polymer material having the ability to retain positive charge characteristics, negative charge characteristics, or zwitterionic characteristics, has a large amount of foam, and has high foam persistence. It is disclosed. Patent Document 2 discloses a liquid detergent composition excellent in foam stability, which contains a polymeric surfactant. Patent Document 3 discloses a liquid detergent composition using a surfactant and a polyethyleneimine-based polymer and having excellent foaming durability.

-C-4: linear / branched mixed alcohol [Isalchem 123 (containing 12 alkyl groups and 13 alkyl groups, branching rate is 94 mol%) manufactured by Sasol Co.] 0.6 mol PO After addition, compound sulfated with sulfur trioxide and neutralized with sodium hydroxide (average molecular weight: 295)

<Evaluation of foaming power during cleaning>
A commercially available sponge (manufactured by Kikuron, material: polyurethane / nylon, 11.5 cm long, 7.5 cm wide, 3.5 cm high) was gently rinsed with tap water at 25 ° C. and washed 20 times with water. The sponge was squeezed firmly until it was impregnated. After 1 g of the composition was weighed on the sponge, the sponge was further impregnated with 20 mL of 25 ° C. tap water. From this state, the sponge was squeezed five times, and all the foam that was foamed at that time was collected in a 500 mL glass graduated cylinder, and the amount of foam at that time was read from the scale. This value was taken as the foaming power of the composition.

<Evaluation of foam disappearance during rinsing>
The composition was diluted to 3.2% with 3.5 ° DH hard water, and 3 g was obtained by using a pump former (manufactured by Kao Corp., used in the Cucut citric acid effect foam type (released in 2007)). Was produced in a 500 ml glass graduated cylinder, and the volume was recorded from the scale of the graduated cylinder (initial amount of foam). Next, the operation of adding 100 ml of 3.5 ° DH hard water to the foam through a handmade water jet and then adding 100 ml of hard water every 1 minute thereafter was carried out three times in total (adding 100 ml of hard water four times in total. The total amount added was 400 ml), and the amount of foam 30 seconds after the addition of hard water was measured. The hand-made water bottle is made by removing about one-third of the bottom of a 250 ml polypropylene wide-mouthed bottle (Aswan: Eyeboy wide-mouthed bottle), and uniformly opening 13 holes with a diameter of about 2 mm in the opening with the lid removed. A thin plastic perforated plate with the opening opened was fixed. About foam extinction property, it calculated | required from the foam amount change rate shown by following Formula, and made what passed 30% or less at the time of 400 ml total addition.
Foam amount change rate (%) = (foam amount after addition of 400 mL of hard water / initial foam amount) × 100

  From the results in Table 1, it can be seen that the compositions of the examples are excellent in foaming power at the time of washing and foam disappearance at the time of rinsing.
