Description

Technical Field

[0001] This invention relates to the field of additive-free baby wipes, specifically to a type of additive-free baby wipe. Background Technology

[0002] The market is flooded with baby wipes, but almost all of them contain bactericides, primarily quaternary ammonium salts such as benzalkonium chloride. Due to the special nature of infants' skin, long-term and frequent use of wipes containing quaternary ammonium salt cationic ingredients can cause skin redness, itching, and in severe cases, even rashes and ulcers. On the other hand, using polylysine hydrochloride instead of benzalkonium chloride as a bactericide in the formula results in poor bactericidal effect.

[0003] The unique physiological characteristics of infant and adult skin are as follows:

[0004] 1. Large body surface area, making them prone to dehydration; 2. Thin and delicate skin, resulting in poor skin barrier protection. External environmental stimuli such as excessive cold or heat, friction, and residues of feces and other substances can lead to dry, red, and itchy skin.

[0005] To address the aforementioned issues, existing technologies utilize the antibacterial activity of a natural extract—raspberry ketone. By adding raspberry ketone, the dosage of other additives such as preservatives can be reduced, thereby achieving better skin-feel properties. For example, patent document CN 114983834 A discloses a preservative-free wet wipe comprising a base fabric and a formulation liquid permeated with the base fabric. This formulation liquid contains raspberry ketone, with the raspberry ketone accounting for 0.05% to 0.5% of the formulation liquid by mass. However, in actual formulation, it was found that the formulation liquid containing raspberry ketone has a high viscosity, reaching 2 cP. This results in a sticky wet wipe product, leaving significant residue on the skin of infants and young children, which, with long-term irritation, can damage their skin. Summary of the Invention

[0006] In view of this, the present invention provides an additive-free baby wipe that has low viscosity when wiping away residue, good bactericidal effect, and will not irritate the skin.

[0007] To address the aforementioned technical problems, this invention provides additive-free baby wipes, comprising a formula liquid and a base fabric. The formula liquid contains raspberry ketone and is further formulated with caprylyl glycol and ethylhexylglycerin, wherein the ratio of caprylyl glycol to ethylhexylglycerin is as follows:

[0008] Octyl glycol: 0.03%–0.06%;

[0009] Ethylhexylglycerin: 0.02%–0.06%.

[0010] This invention reduces the overall viscosity of the formula by using caprylyl glycol. Caprylyl glycol typically functions as a preservative in wet wipes and skincare products. It is considered one of the relatively safe preservatives, inhibiting yeast and Gram-negative bacteria. At this concentration, it is non-irritating and can synergistically enhance the effects of other preservatives (i.e., 1,2-propanediol and hexanediol). The hydrophilic group of caprylyl glycol reduces the viscosity of raspberry ketone and other additives in the formula. Then, ethylhexylglycerin is used as a modifier to enhance the preservative and hydrophilic effects of caprylyl glycol itself, effectively reducing the amount of caprylyl glycol used. This allows a small amount of caprylyl glycol to achieve the same effect as using more. The reduced amount of caprylyl glycol and other additives further reduces the irritation and viscosity of the wet wipes, ensuring that the formula residue left on the baby's skin after use is easily evaporated and removed, thus protecting the baby's skin.

[0011] Furthermore, the base fabric is a spunlace nonwoven fabric.

[0012] Furthermore, the raspberry ketone accounts for 0.1%-0.4% of the mass percentage of the formulation solution.

[0013] Multiple experiments have shown that raspberry ketone, at a mass percentage range of 0.1%-0.4%, can effectively inhibit Escherichia coli, Staphylococcus aureus, and Candida albicans, while also controlling the excessive use of preservatives, reducing the amount of preservatives used, and minimizing skin damage.

[0014] Furthermore, the formulation also includes cetylpyridinium chloride, 1,2-propanediol, and hexanediol.

[0015] Furthermore, the cetylpyridinium chloride accounts for 0.02%-0.06% of the mass percentage of the formulation solution.

[0016] Cetylpyridinium chloride is a nitrogen-containing cationic surfactant, primarily used as a bactericide and disinfectant. It is a cationic quaternary ammonium salt that achieves its bactericidal effect mainly by altering cell membrane permeability and does not induce drug resistance. It is effective against both Gram-positive and Gram-negative bacteria at pH 4–10, exhibiting broad-spectrum bactericidal activity.

[0017] Furthermore, the 1,2-propanediol accounts for 0.3%-0.6% of the mass percentage of the formulation solution.

[0018] 1,2-Propanediol is a safe and mild ingredient, mainly used as a preservative, moisturizer, thickener, and solvent. As an organic polyol moisturizing solvent, it helps ingredients penetrate the skin.

[0019] Furthermore, the hexanediol accounts for 0.1%-0.4% of the mass percentage of the formulation solution.

[0020] Hexanediol, as a raw material, is a polyol that can synergistically combine with other antimicrobial substances to achieve moisturizing, anti-allergic, antibacterial, deodorizing and antiperspirant effects, while being gentle on the skin.

[0021] Furthermore, the specific preparation steps for the formula liquid are as follows:

[0022] S1. Weigh out each raw material according to the proportion;

[0023] S2. Dissolve raspberry ketone in 1,2-propanediol and stir to obtain mixture A;

[0024] S3. Next, mix octyl glycol and ethylhexylglycerin, add mixture A, and stir to obtain mixture B;

[0025] S4. Add cetylpyridinium chloride and hexanediol to mixture B in sequence, add water weighed according to the proportion, stir evenly to obtain the formula solution.

[0026] Furthermore, the water in step S4 is EDI pure water.

[0027] Furthermore, the stirring time in step S4 is 15-20 minutes.

[0028] In summary, this application has at least one of the following beneficial technical effects compared with the prior art:

[0029] 1. The raspberry ketone in this invention application is a potent inhibitor that has a great inhibitory effect on Staphylococcus aureus, Candida albicans, and Escherichia coli. It can greatly reduce the use of other preservatives. The preservative (polyol raw material) can improve the antibacterial properties of the wipes and inhibit the discomfort caused by Staphylococcus aureus, Candida albicans, and Escherichia coli.

[0030] Raspberry ketone and other preservatives are sprayed evenly and effectively onto the spunlace nonwoven fabric, enabling it to effectively inhibit bacteria and moisturize, thus protecting the skin of infants and young children. When used on patients with sensitive skin, it has a significant effect on improving the symptoms of infants and young children with sensitive skin.

[0031] 2. Another beneficial effect of the present invention is that the use of 0.03% to 0.06% caprylyl glycol reduces the viscosity of the inventive formula liquid, so that the finished wet wipes are less sticky and have less residue after use, and will not harm the skin of infants and young children with long-term use.

[0032] 3. The beneficial effect of this invention also lies in the use of cetylpyridinium chloride, which changes the cell membrane permeability of the bacteria to be killed at the molecular level, thereby killing the bacteria without causing them to develop drug resistance, and can be used for a long time.

[0249] As can be seen from Examples 1 to 8, the octyl glycol of the present invention, within the range of 0.03-0.06%, can effectively ensure sterilization efficiency and low viscosity.

[0250] As can be seen from the comparison between Comparative Example 1 and the Example, although the present invention achieves the sterilization rate by using excessively high levels of caprylyl glycol, the viscosity is higher than 1.5 cP, which is unacceptable. Therefore, simply pursuing a high sterilization rate cannot make the wipes have the corresponding low viscosity, thus avoiding damage to infants' skin.

[0251] As shown in Comparative Example 2, when using high-concentration ethylhexylglycerin, using 0.10% ethylhexylglycerin will result in excessive viscosity in 0.03-0.06% octyl glycol wipes, which does not meet the viscosity effect required by the present invention.

[0252] Comparative Example 3 also shows that although the use of polylysine hydrochloride satisfies the requirement of low irritation, the bactericidal efficiency is low and it does not have the corresponding bactericidal ability.

[0253] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
