Description

  The present invention relates to a cleaning agent for a vehicle body (including window glass) (hereinafter also referred to as a vehicle body) of an automobile or the like, in particular, a car wash for a vehicle, for example, a cleaning agent for cleaning a vehicle body, a vehicle body, particularly a painted surface thereof. The present invention relates to a wax agent or the like for imparting water repellency to water.

  So far, as car body cleaning agents, shampoos made of cleaners and foams made from petroleum-derived surfactants and animal and plant-derived surfactants, and waxes such as petroleum paraffin and wax are often used. These cleaning agents are generally applied to the vehicle body through a car wash machine and used for car wash processing (see, for example, cited document 1).

  In recent years, chemicals with low environmental impact have been developed in consideration of environmental issues, and in particular, chemicals based on chemicals whose raw materials have been changed from petroleum to animals and plants have been studied. The depletion of the problem is regarded as a problem.

  Under such circumstances, an object of the present invention is to provide a vehicle body cleaning agent that uses a used raw material that is derived from animals and plants and is not virgin. .

  As a result of earnest research to achieve the above-mentioned problems, the present inventors paid attention to waste cooking oil to the extent that most of it is used for livestock feed and partially reused as a raw material for fuel. Was used as a raw material for a vehicle body cleaning agent, it was found to exhibit performance inferior to that of virgin even though it was used, and the present invention was made based on this finding.

That is, the present invention is as follows.
(1) A vehicle body cleaning agent comprising at least one agent selected from recycled fatty acid-derived fatty acid esters, polyethylene glycol fatty acid esters, and fatty acid soaps, which are derived from waste cooking oil.
(2) The vehicle body cleaning agent according to (1), further comprising a surfactant.

  The car body cleansing agent of the present invention is not inferior to those using virgin products such as those derived from genuine fatty acids, despite using a recycled fatty acid-derived chemical sourced from used waste cooking oil. It has the advantage of showing performance.

2 is an FT-IR chart of a base soap in Example 1. FIG. 2 is an FT-IR chart of polyethylene glycol fatty acid ester in Example 10. FIG.

  The vehicle body cleansing agent of the present invention comprises at least one agent selected from polyethylene glycol fatty acid esters derived from recycled fatty acids, fatty acid esters, and fatty acid soaps that are made from waste edible oil.

  Although it does not specifically limit as waste cooking oil, For example, the used cooking oil etc. which were used for manufacture of processed foods, such as fried food, were discarded. Examples of edible oils include salad oil, soybean oil, rapeseed oil, canola oil, olive oil, sesame oil, corn oil, safflower oil, palm oil, safflower oil, safflower oil, rice oil, sunflower oil, peanut oil, coconut oil, Examples thereof include cocoa oil and rice bran oil.

  The polyethylene glycol fatty acid ester is an ester obtained by reacting a recycled fatty acid and polyethylene glycol. As the polyethylene glycol, those having a molecular weight of 200 to 20000, preferably 400 to 4000 are used.

The fatty acid ester is an ester obtained by reacting a recycled fatty acid with an aliphatic monoalcohol.
In order to use this fatty acid ester as a wax agent, the aliphatic monoalcohol is preferably linear or branched having 8 to 22 carbon atoms.

The fatty acid soap is a recycled fatty acid alkali metal salt or a salt of recycled fatty acid and amine.
Examples of the amine include monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, methyldiethanolamine, morpholine and the like.

In order to enhance the performance as a cleaning agent, various surfactants such as an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant can be added to these agents.
The addition amount of the surfactant is preferably selected in the range of 1 to 20% based on the weight with respect to the cleaning agent.

  Among such surfactants, examples of the anionic surfactant include alkyl sulfate ester salts, polyoxyethylene alkyl sulfate ester salts, and alkane sulfonate salts.

  Nonionic surfactants include, for example, alkyl ether ethylene oxide adducts, alkylphenyl ether ethylene oxide adducts, polyoxyethylene fatty acid esters (fatty acid ethylene oxide adducts and polyethylene glycol fatty acid esters, hardened castor oil ethylene oxide adducts), sorbitan fatty acids. Examples include ester ethylene oxide adducts, aliphatic amine alkylene oxides (for example, polyoxyethylene alkylamines), alkyl alkanolamides, alkylamine oxides, alkylamidopropylamine oxides, and the like.

  Examples of amphoteric surfactants include alkyl betaines and alkyl amide betaines.

  When the vehicle body cleaning agent is used as a wax agent, a surfactant, especially a nonionic surfactant or a cationic surfactant is blended in order to efficiently disperse, emulsify and dissolve in water. Is preferred.

  Examples of the cationic surfactant include monoalkyl ammonium chloride, dialkyl ammonium chloride, ethylene oxide adduct of alkyl ammonium chloride, and alkylamine acetate.

  Although the vehicle body cleaning agent of the present invention depends on the type of active ingredient, it is preferable that the active ingredient concentration is adjusted to about 1 to 20% by weight, and this is applied to the vehicle body via a car wash machine or the like. In car washing treatment such as washing or waxing, it is practically preferable to dilute with water until the preferred concentration is 20 to 1000 times.

  In addition, the vehicle body cleaning agent of the present invention is blended with optional additive components such as organic solvents, ultraviolet absorbers, dyes, rust preventives, preservatives and the like as long as they do not impair the purpose of the present invention. be able to.

  EXAMPLES Next, although an Example demonstrates this invention further in detail, this invention is not limited at all by these examples.

Example 19 and Comparative Example 9
The wax agent which consists of various components of the predetermined dose shown in following Table 3 was prepared, and the performance of this wax agent was evaluated. The evaluation method is to create a coated plate by baking paint for automobile body made of acrylic-melamine resin in the laminated form of base coat and top coat on the plated steel plate material for automobile body. After polishing, washing and air-drying to prepare a test piece, each wax agent was applied to the test piece after being diluted 20 times, and the contact angle to water on the obtained coating film was measured with a contact angle measuring device (Kyowa). Measured using an interface DropMaster). The results are shown in Table 3.

  From this, it can be seen that when the waste edible oil-derived fatty acid ester is used as a water repellent component, it has performance comparable to conventional wax agents mainly composed of paraffin wax and olefin wax.
