Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning composition that has strong cleaning power, causes little environmental pollution, and has low foaming properties.

[Conventional technology] It has long been known that terpene compounds such as limonene and pinene have excellent cleaning power, and focusing on their low environmental pollution such as ozone depletion and accumulation in the natural world, It has been proposed that it can be used as a cleaning agent for stains on substrates, etc.

For example, Japanese Unexamined Patent Publication No. 54-14406 discloses a cleaning agent for hands, carpets, glass, etc. made of D-limonene, a surfactant, and water; discloses a printed wiring board cleaning agent comprising a terpene compound and a surfactant.

[Problem to be solved by the invention]

However, the surfactants used in the art to date are ethylene oxide adducts such as alkylbenzene sulfonates, polysorbate esters, alcohol ethoxylates and ethoxysulfonates, alkyl and dialkyl sulfosuccinates, alkylphenyl ethoxylates, sulfuric esters, sulfonate Since the detergent was an acid ester, there was a problem in that the waste water was very prone to foaming during or after use of the detergent. Foam does not pose a particular problem when used on a small scale, such as in the home, but when used industrially, there are problems such as foam overflowing from the tank and the need for an unnecessarily large cleaning device.

The present invention aims to eliminate these drawbacks and provide a cleaning composition with low foaming properties and less environmental pollution.

[Means for Solving the Problems] The present inventors have discovered that a cleaning composition comprising a terpene compound and a specific compound having surface activity has excellent cleaning power, low foaming properties, and is environmentally friendly. The present invention was completed after discovering that there is less contamination.

That is, the present invention is a cleaning composition comprising a terpene compound and a compound represented by general formula (1).

Examples include sucrose, raffinose, gentianose, melezitose, and their partially etherified or esterified products; and phenols such as catechol, resorcinol, hydroquinone, and phloroglucin.

The oxyalkylene group having 3 to 18 carbon atoms represented by AO includes oxypropylene group, oxybutylene group, oxytetramethylene group, oxystyrene group, oxyalkylene group, oxytetramethylene group, oxyhexadecylene group, oxyocta Examples include decylene groups, and only one type of these groups may be added, or two or more types thereof may be added at the same time.

Hydrocarbon groups having 1 to 24 carbon atoms represented by R1 include methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, tert-butyl group, hentyl group, isopentyl group, hexyl group, heptyl group, 2-ethylhexyl group, octyl group, nonyl group, decyl group, undecyl group, dodecyl group, tridecyl group, tetrazo°cyl group, hexadecyl group, isohexadecyl group, octadecyl group,

There is an acyl group derived from gallic acid, etc.

In general formula (1), at least 1 mole of oxyethylene group is required to make the terpene compound emulsifiable in water. It is preferable to include A◯ in order to make the waste water after washing less foamy, but it is not always necessary. In addition, the total number of added moles of oxyalkylene groups and oxyethylene groups needs to be 2 moles or more in order to have surface-active ability, and if it exceeds 500 moles, the viscosity increases significantly and it becomes difficult to use, so it should not exceed 500 moles. It requires something. In addition, the content of oxyethylene groups may be any amount suitable for emulsifying the terpene compound in water, and is not particularly limited as it varies depending on the type of terpene compound or the combination of compounds represented by general formula (1). However, if a natural oil such as orange beer oil is used, the preferred amount of ethylene oxide is 20 to 80% by weight of the molecular weight.

Moreover, the oxyalkylene group and the oxyethylene group may be added in a block form or may be added in a random form.

The proportion of the compound represented by general formula (1) in the detergent composition is the amount necessary to emulsify the terpene compound and cannot be particularly limited, but it is 2 to 40% by weight in order not to reduce the detergency. A range of is preferred.

(Effects of the Invention) The cleaning composition of the present invention combines a terpene compound and a low-foaming surfactant compound that can self-emulsify the terpene compound, so it can be used to remove household oil stains and print substrates. Easy to remove stains from rosin flux, liquid crystal, etc.
It is a cleaning agent that is extremely easy to rinse with water, can be easily treated as wastewater, and causes little environmental pollution.
