Description

  The present invention relates to a dusting agent applied to a cleaning tool such as a mop or a shoe wiping mat.

  Conventionally, as a dusting agent used by being held on a cleaning tool such as a mop or a shoe wiping mat, a lipophilic (hydrophobic) liquid such as liquid paraffin or isoparaffin described in Japanese Patent No. 2576937 (Patent Document 1). Is used as a main component. When such mop yarns with conventional dusting agents are used for wiping and cleaning floors, furniture, etc., dust can be adsorbed by the adhesive force of the lipophilic liquid in the dusting agent, and its lipophilicity Due to the effect of the liquid, the mop yarn or the like is slightly charged with static electricity, and dust is easily taken into the mop yarn or the like.

  However, the adsorption power of lipophilic liquid to dust is not always strong. In addition, the amount of static electricity generated by the lipophilic liquid varies greatly depending on how it is used. However, since static electricity is generated in the mop yarn itself, the static electricity on the cathode ray tube screen and other places cannot be removed, and there is a risk of reattachment of dust.

  Furthermore, lipophilic liquids such as liquid paraffin and isoparaffin, which are the main components of conventional dusting agents, are accompanied by a risk of ignition and are not easy to wash away when they adhere to the user's hand.

  Japanese Patent No. 3411105 (Patent Document 2) describes an invention of a “dust control agent mainly composed of a solution comprising 50 to 70% by weight of propylene glycol and 50 to 30% by weight of water”.

  In the case of a dusting agent using an organic solvent or mineral oil, the present invention is `` After cleaning, an oil film remains on the target surface such as the floor, and it cannot be removed by water wiping, so the floor surface is slippery, In addition, the oil film tends to yellow and discolor, and the appearance of the cleaned floor may be damaged. The lightness of the mop, the finish, the sustainability of the effect, and the cleaning It is intended to provide a dusting agent having good properties.

  However, this dusting agent has room for further improvement in the persistence of the dusting effect in a mop or the like, and in particular in the uniformity of the dusting effect when the dusting agent is applied to a mop or the like in a general household.

JP-A-2003-81842 (Patent Document 3) discloses a wiping sheet obtained by impregnating a base material with an allergen-reducing component, and discloses an aromatic hydroxy compound and the like as the allergen-reducing component, Examples of the solvent for dissolving or dispersing the allergen-reducing substance include water, alcohols, hydrocarbons, ethers, ketones, amides and the like. However, the persistence of the dusting effect in mops, etc., in which allergen-reducing substances are dissolved or dispersed in such a solvent, and the uniformity of the dusting effect especially when dusting agents are applied to mops, etc. in general households I couldn't say enough.
