Description

Technical Field

[0001] The present disclosure relates to a method for preparing a cleaning composition, and more specifically, to a method for preparing a biodegradable cleaning solution.

Background Art

[0002] Detergents are used as cleaning agents worldwide. Such large-scale use generates a large amount of waste and further causes environmental pollution.

[0003] In this regard, over the past 30 years or more, many studies have been conducted, including treatment, alternatives to non-biodegradable detergents, and the impact on the environment. It has been found that even if a particular detergent is not directly toxic, at high concentrations in the soil, it may act as an agent that releases toxic pollutants such as polychlorinated biphenyls (PCBs). Furthermore, detergents enter wastewater treatment plants and may inhibit the performance of the plants. Detergents are an essential element of human life and are used for various hygienic purposes. Laundry detergents have a fresh smell like morning dew but contain very strong chemicals to remove stains and dirt. People experience the regular adverse effects of the components present in standard detergents on their skin. Laundry detergents can cause a condition called contact dermatitis, resulting in itchy red rashes that can spread widely or occur in specific areas such as under the armpits or groin. Allergies and sensitivities to laundry detergents can develop when a person is first exposed to the detergent or after repeated exposure. According to a report by NationalEczema.org, one in ten people will develop eczema in their lifetime, and the prevalence will peak in childhood. Furthermore, SLS / SLES, which is commonly used as the main surfactant in household detergents, is known as a skin irritant.

[0004] In detergents available in the prior art, it has not been verified that they do not contain SLES / SLS, formaldehyde, phosphates, EDTA, parabens, phthalic acid esters, and CDE / betaine in the formulation. Therefore, there is a need for a method to prepare a biodegradable detergent that can function as an alternative to non-biodegradable standard detergents, which are the cause of environmental and health problems.

Examples

[0042] Example 1: A biodegradable detergent was prepared using the following components.

Table 1

[0043] Example 2: Implementation of the biodegradability test OECD 301D (closed bottle) for the biodegradable cleaning liquid according to the exemplary embodiment of this specification, and its results. Formula for calculating the percentage of ready biodegradability = (BOD of the sample / COD of the sample) × 100 {When the standard parameter - reaches ≤ 60% in 28 days, the sample is considered biodegradable}

Table 2

[0044] Result - 95.5% of the prepared detergent is biodegradable in 28 days, and thus it is essentially environmentally friendly.

[0045] Example 3: In one provided example, spectral analysis was performed to compare the standard sodium lauryl sulfate with this biodegradable cleaning liquid. The results of the spectral analysis performed are shown in Figure 2 of the drawings, and it has been observed that the similarity between the prepared detergent and the sodium lauryl sulfate standard reaches only 31.69%, which confirms that the prepared sample detergent of the present invention does not contain SLES.

Table 3

[0046] This test was carried out using the MS1079:1987 method. Titration was performed using a high amine solution to measure the SLES content.

[0047] Example 4: High - performance liquid chromatography (HPLC) and the OF063 method, and their results, for testing that the biological cleaning liquid according to an exemplary embodiment of this specification does not contain parabens, phosphates, and phthalic esters.

Table 4

[0048] Results: The abundances of parabens and phthalate esters were found to be below the limit of reporting (LOR), and thus were considered non-detects (ND) and concluded to be absent from the prepared detergents. Phosphoric acid was detected only in trace amounts, indicating that no additional phosphoric acid was present in the prepared detergent samples.
