Description

Technical Field

[0001] The present invention relates to the technical field of detergents, and in particular to a detergent composition that is highly effective in decontamination, safe, low-irritating and environmentally friendly, and a preparation method thereof. Background Art

[0002] Dishwashing liquids are commonly used by businesses, households, and individuals to clean dishes and grease. Their performance impacts human health and environmental sustainability. Traditional dishwashing liquids primarily rely on surfactants (such as sodium lauryl sulfate and sodium lauryl sulfate) to achieve their cleaning effect. According to research by Colby L. Presley, BS, BA, Michelle Militello, MS, Cara Barber, MD, Ryan Ladd, MD, Melissa Laughter, PhD, Heather Ferguson, PhD, Jesse Dewey, BS, Kayd J. Pulsipher, BS, Chandler W. Rundle, MD, and Cory A. Dunnick, MD, traditional surfactants may alter the skin barrier by disrupting lipids in the stratum corneum, leading to ICD. Anionic surfactants are widely considered strong irritants, while cationic surfactants are considered equally irritating but more cytotoxic. Nonionic surfactants have the lowest irritation potential. For example, sodium lauryl sulfate damages keratinocytes and keratin, downregulating structural proteins and lipids. It also disrupts tight junctions, causing damage to proteins such as keratin, cephalosporin, profilin, and loricrin. This exposes new water-binding sites, leading to overhydration of the stratum corneum and disruption of the lipid bilayer. Common dishwashing liquids on the market contain irritating surfactants (such as sodium lauryl sulfate and sodium lauryl sulfate), which can easily cause dryness or allergies in the skin, leading to irritant contact dermatitis. This is particularly harmful to hands with wounds. Furthermore, excessive foaming and other factors can lead to inadequate rinsing and residue. For example, random inspections of tableware have revealed the presence of dishwashing liquid residue. For example, the Suzhou Industrial Park Food Safety Inspection Notice (Issue 2, 2025) revealed that five batches of chopsticks, two batches of spoons, and one batch of plates were found to contain substandard anionic synthetic detergents.

[0003] In addition, traditional dishwashing liquids have poor environmental performance, low biodegradability, and a burden on the aquatic environment. For example, the environmental safety evaluation of surfactants (LAS & NIS) published by Yuan Pingfu, Liao Bohan and Lu Ming showed that anionic surfactants linear alkylbenzene sulfonate (LAS) and nonionic surfactants (NIS) are two types of surfactants with considerable production and consumption. The article analyzed their environmental safety from three aspects: biodegradability, toxicity, and accumulation in the environment and organisms. It is believed that surfactants (traditional surfactants) will have different degrees of impact on the environment. LAS is toxic to animals and plants and accumulates in the environment and organisms (although it is easily degradable), which should be taken seriously. The degradation products of fatty alcohol polyoxyethylene ether (APEO) in NIS are highly toxic and degrade slowly, posing a great threat to the environment.

[0004] Emulsifiers are often used in the food and pharmaceutical fields to reduce the surface tension of oil and water to produce water-in-oil solution products. Although the principle of producing water-in-oil solution is the same as the principle of removing oil stains, and food and pharmaceutical emulsifiers are safe and environmentally friendly, there are few stable emulsifiers that can remove oil stains at room temperature and the steps are complicated, making industrial production difficult. Therefore, a method for preparing a detergent composition comprising a formula of common edible and medicinal substances, which is efficient in decontamination, safe, low-irritation and environmentally friendly, and a preparation method thereof are proposed. Summary of the Invention

[0005] In view of this, the present invention proposes a method for preparing a detergent composition that has high decontamination ability, is safe, has low irritation and is environmentally friendly to solve the above problems.

[0006] The technical solution of the present invention is achieved as follows: A highly effective, safe, low-irritation, and environmentally friendly dishwashing liquid composition and its preparation method.

The active ingredients include mono- and diglycerol fatty acid esters, polysorbate 80, and glycerol. The oil phase component includes mono- and diglycerol fatty acid esters, and the aqueous phase component includes polysorbate 80, glycerol, sodium bicarbonate, and water.

[0007] Furthermore, a method for preparing a detergent composition having high decontamination ability, safety, low irritation and environmental friendliness comprises the following steps: Step 1: Prepare solution A: Heat and melt mono- and di-glycerol fatty acid esters to obtain solution A.

[0008] Step 2: Prepare solution B: Add polysorbate 80, glycerol, sodium bicarbonate and 70-100°C hot water and stir until the sodium bicarbonate is dissolved and the solution is mixed evenly to obtain solution B.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The formula of the present invention uses all commonly used edible and medicinal substances, has good safety, low irritation, reduces the impact on the environment, and has little potential harm to the human body.

[0011] The process of the present invention is simple, has good stability, is easy to achieve industrial production, and various raw materials are easily available and inexpensive, so the industrial production cost is low.
