Abstract

PURPOSE:To provide a detergent improved in detergency and safety, by blending a detergent for hard surfaces with a polyoxyalkylene benzyl ether. CONSTITUTION:At most 5mol. of polyoxyalkylene chains (b), pref. polyoxyethylene or polyoxypropylene, are added to benzyl alcohol (a) to prepare a polyoxyalkylene monobenzyl ether (B), which is then blended with a detergent for hard surfaces (A).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning agent that is safe and has excellent cleaning properties. Specifically, the present invention relates to a cleaning agent for hard surfaces in which a novel solvent with excellent safety and high solvent properties is added for the purpose of enhancing the cleaning effect.

[Conventional technology]

Cleaning hard surfaces such as floors, glass, tiles, and walls often requires the use of a combination of acids, alkalis, and solvents because they often contain dirt that is very difficult to remove. For example, floor wax, which is a mixture of resin and wax, is applied to the floor to protect it and give it a shine, and dirt, asphalt, and oil stains on shoes are rubbed off against this floor wax. It is strongly stuck to the floor because it has been stepped on or stepped on. Paint may adhere to walls, glass, etc., and proteins released from the human body often adhere to tiles.

In order to remove such a variety of stains, a cleaning agent must combine the effects of penetrating and emulsifying effects using an interfacial agent, saponification and dispersing effects using an alkali, and stain dissolution using a solvent.

Solvents used in such cleaning agents include cellosolve, carbitols, polypropylene glycol, and benzyl alcohol.

[Problem that the invention seeks to solve]

The requirements for such a solvent include: it must be safe, it must not emit any strange odor during or after work, it must have excellent solvent properties to enhance the cleaning effect, and it must be resistant to water. To dissolve, etc. - to be blown away. However, the solvents conventionally used have advantages and disadvantages, and the reality is that they are unavoidably used despite their problems.

Among cellosolve and carbitol, butyl cellosolve is often used because it has excellent detergency. However, in recent years, in the United States, the EPA (US Environmental Agency) has
A: We have recommended these preventive regulations to the US Department of Labor Safety and Health Administration, based on our judgment that they will cause problems such as testicular shrinkage, blood disorders, and abnormalities in the reproductive organs. OSHA has acknowledged this and has submitted a draft rule. Thus, the use of cellosolves has become a social problem.

Although polypropylene glycol does not have such safety problems, its cleaning performance is several steps lower, so it cannot be used in various cleaning agents.

Although benzyl alcohol has excellent solvent properties, it has the drawback of not being soluble in water, and in order to use it, it is necessary to use more surfactant than necessary in order to solubilize the pencil alcohol.

Cleaning agents that use a large amount of surfactants in this way are not only expensive, but also tend to foam easily, requiring a large amount of rinse water to wash away the cleaning agent, and rinsing may be insufficient. This results in disadvantages such as excess surfactant remaining and causing stains.

[Means for solving problems]

We have conducted extensive research to develop a cleaning agent that does not have these problems, and have discovered an ideal cleaning solvent that satisfies all of these requirements.

That is, it has been found that when polyoxyalkylene is added to benzyl alcohol, it becomes water-soluble, reduces odor, is excellent as a cleaning solvent, and has excellent safety.

The polyoxyalkylene chain is preferably polyoxyethylene or polyoxypropylene, and a combination of these two types may also be added. As the polyoxyalkylene chain becomes longer, the water solubility increases and the odor decreases, but the solvent property decreases and the performance as a cleaning solvent deteriorates. When the number of moles added was examined in detail, it was found that 5 moles or less had excellent performance as a cleaning solvent.
