JP5838477B2 - Cleaner for vehicle body - Google Patents

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.

JP 2002-348597 A

  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) viewed contains a polyethylene glycol fatty acid esters derived from recycled fatty acid to Minamotoshi waste cooking oil, body cleaning agent, characterized in that by blending a further myristyl dimethyl amine oxide.

  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 polyethylene glycol fatty acid ester in Reference Example 1 .

  The vehicle body cleansing agent of the present invention comprises a polyethylene glycol fatty acid ester derived from recycled fatty acid using waste cooking oil as a source.

  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.

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 the agent.
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.

Reference Examples 1-5, Example 1, Reference Examples 7-9
1 part by weight of recycled fatty acid (TFA-140F) and 4 parts by weight of polyethylene glycol (600), which are waste edible oil sources manufactured by Tsukino Food Industry Co., Ltd., were mixed with stirring. The mixture was heated to 80 ° C., 0.03 weight of sulfuric acid was added thereto, and the mixture was stirred at 80 to 90 ° C. for 90 minutes. Thereafter, it is allowed to cool to room temperature to prepare a cleaning liquid containing polyethylene glycol fatty acid ester as a main cleaning component, and a cleaning liquid obtained by adding 5% by weight of various surfactants to this cleaning liquid as shown in Table 1 below. Were prepared and used as car wash samples.

The FT-IR chart of the polyethylene glycol fatty acid ester in Reference Example 1 is shown in FIG. In the figure, the peak derived from the C = O stretching vibration of the carboxyl group dimer of the waste oil-derived fatty acid in the vicinity of 1700 cm ^{-1 in} (B) is not seen in (C), and the peak is in the vicinity of 1735 cm ^-1. It can be seen. Since this is a peak derived from the stretching vibration of C = O of the ester, it was confirmed that the ester was generated from the polyethylene glycol and the fatty acid by the above method.

Than this, towards the car wash agent of Reference Example and Examples by the cleaning liquid to a polyethylene glycol fatty acid ester derived from waste cooking oil as a main cleaning component is the commercially available washing solution equal to or higher than the level, especially the surfactant is blended It can be seen that the overall performance is superior to that of the comparative example.
In particular, the performance can be greatly improved by adding myristyldimethylamine oxide to the main cleaning component.
Therefore, effective utilization of resources, such as recycling of waste cooking oil, can be further expanded by using the present invention.

  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. Since it shows performance, it can be used greatly in industry.
