Description

Technical Field

[0001] This application belongs to the field of toilet cleaning technology, specifically relating to foam shields and their preparation methods. Background Technology

[0002] With the development of technology and the improvement of people's living standards, toilets have become a common household item. However, the water ring in the toilet bowl easily splashes water during urination and defecation. This water contains various harmful bacteria, which can easily spread various diseases if splashed onto the human body, especially affecting women's health. Therefore, foam shields have emerged. Foam shield products produce foam when mixed with water, and can even form a foam shield to prevent toilet water from splashing.

[0003] The dirt on the toilet mainly consists of fecal matter, limescale, and dust deposits. Fecal matter and dust are easily flushed away by water, while fecal matter and limescale are difficult to flush away. Over time, they form a layer of "yellow grime" on the toilet surface, which greatly affects the user experience.

[0004] Existing foam shields on the market are mainly used to prevent toilet water from splashing and have antibacterial functions. However, in terms of deodorization, they mainly use fragrances to mask the odor and cannot achieve a good deodorizing effect. In addition, existing foam shields do not have a scale-inhibiting effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a foam shield and its preparation method. The foam shield of this application not only has excellent scale inhibition and deodorization effects but also highly efficient bactericidal effects. This application prevents scale formation by reacting trisodium phosphate with metal cations in water to generate a water-soluble chelating agent, thereby preventing the agent from combining with other scale-forming anions in the water. Citric acid is used to treat β-cyclodextrin, which can encapsulate and adsorb odor molecules, achieving deodorization. Furthermore, β-cyclodextrin forms an inclusion complex with the fragrance molecule lemon essential oil, reducing the volatilization of the fragrance molecule lemon essential oil and providing a slow-release effect, thus masking odors. The broad-spectrum bactericides imazalil and p-chloro-m-xylenol are used to achieve highly efficient bactericidal effects.

[0006] In one aspect, this application provides a foam shield comprising the following raw materials in parts by weight: 15-22 parts of potassium cocoyl glycinate, 4-8 parts of sodium cocoamphoacetate, 3-6 parts of cocamidopropyl betaine, 3-5 parts of sorbitol, 2-4 parts of glycerol, 8-15 parts of trisodium phosphate, 6-11 parts of cyclodextrin, 1-2 parts of organic acid, 0.5-2.6 parts of broad-spectrum bactericide, 0.6-1.2 parts of fragrance, and the balance being water.

[0007] In the embodiments of this application, the foam shield comprises the following raw materials in parts by weight: 16-20 parts potassium oleoylglycinate, 5-7 parts sodium cocoamphoacetate, 3-5 parts cocamidopropyl betaine, 3.5-4.5 parts sorbitol, 2.5-3.5 parts glycerol, 9-11 parts trisodium phosphate, 7-9 parts cyclodextrin, 1.2-1.8 parts organic acid, 1.1-2.4 parts broad-spectrum bactericide, 0.6-1.0 parts fragrance, and the balance being water.

[0008] In embodiments of this application, the fragrance is any one of lemon essential oil, rose essential oil, and lavender essential oil.

[0009] In embodiments of this application, the cyclodextrin is any one of α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin.

[0010] In the embodiments of this application, the organic acid is one or two of citric acid, acetic acid, and oxalic acid.

[0011] In an embodiment of this application, the broad-spectrum bactericide is a mixture of imazalil and p-chloro-meta-xylenol.

[0012] In an embodiment of this application, the foam shield comprises the following raw materials in parts by weight: 15 parts potassium cocoyl glycinate, 8 parts sodium cocoamphoacetate, 6 parts cocamidopropyl betaine, 3 parts sorbitol, 4 parts glycerol, 8 parts trisodium phosphate, 6 parts β-cyclodextrin, 1 part citric acid, 0.1 part imazalil, 0.5 parts p-chloro-m-xylenol, 0.6 parts lemon essential oil, and 47.8 parts water.

[0013] In an embodiment of this application, the foam shield comprises the following raw materials in parts by weight: 18 parts potassium cocoyl glycinate, 6 parts sodium cocoamphoacetate, 4 parts cocamidopropyl betaine, 4 parts sorbitol, 3 parts glycerol, 12 parts trisodium phosphate, 8 parts β-cyclodextrin, 1.5 parts citric acid, 0.7 parts imazalil, 1.0 part p-chloro-meta-xylenol, 0.8 parts lemon essential oil, and 41 parts water.

[0014] In an embodiment of this application, the foam shield comprises the following raw materials in parts by weight: 22 parts potassium cocoyl glycinate, 4 parts sodium cocoamphoacetate, 3 parts cocamidopropyl betaine, 5 parts sorbitol, 2 parts glycerol, 15 parts trisodium phosphate, 11 parts β-cyclodextrin, 2 parts citric acid, 1 part imazalil, 1.5 parts p-chloro-m-xylenol, 1.2 parts lemon essential oil, and 32.3 parts water.

[0015] On the other hand, this application provides a method for preparing the above-mentioned foam shield, the method comprising the following steps:

[0016] (1) Weigh the following raw materials by weight according to the composition of the foam shield: 15-22 parts of potassium cocoyl glycinate, 4-8 parts of sodium cocoamphoacetate, 3-6 parts of cocamidopropyl betaine, 3-5 parts of sorbitol, 2-4 parts of glycerol, 8-15 parts of trisodium phosphate, 6-11 parts of cyclodextrin, 1-2 parts of organic acid, 0.5-2.6 parts of broad-spectrum bactericide, 0.6-1.2 parts of fragrance, and the balance is water;

[0018] (3) Add the other components to the above mixture at room temperature and stir evenly to obtain a foam shield.

[0019] The foam shield of this application not only has excellent scale inhibition and deodorization effects, but also highly effective bactericidal effects. This application achieves this by reacting trisodium phosphate with metal cations in water to generate a water-soluble chelating agent, thereby preventing it from combining with other anions in the water that can form scale, thus avoiding scale formation. Citric acid is used to treat β-cyclodextrin, which can encapsulate and adsorb odor molecules, achieving deodorization. Furthermore, β-cyclodextrin forms an inclusion complex with the fragrance molecule lemon essential oil, reducing the volatilization of the fragrance molecule lemon essential oil and providing a slow-release effect, thus masking odors. The broad-spectrum bactericides imazalil and p-chloro-m-xylenol are used to achieve highly effective bactericidal effects.
