Absorbent article
Technical Field
The present invention relates to an absorbent article.
Background
In order to prevent the function of repairing allergic eczema on human skin, skin care agents are often coated on the contact surface contacting with human skin, and some skin care agents contain pectin, such as pectin contained in a water-soluble film in a disposable diaper disclosed in U.S. patent No. US4790836, and chinese patent 2004800347810 also discloses that a 1% pectin aqueous solution is used for the skin care agent, wherein the PH value of the aqueous solution of the pectin is 3-4.
Obviously, the absorbent article can hardly contain the aqueous pectin solution directly, because the water in the aqueous pectin solution can be absorbed by the water-absorbing material in the absorbent article quickly, and the quality performance of the water-absorbing material after absorbing the water in the aqueous pectin solution can seriously affect or can not absorb the moisture such as external urine, so that the performance quality of the absorbent article is seriously affected and even the effect of the absorbent article can not be achieved.
Disclosure of Invention
The invention provides an absorbent article, including but not limited to sanitary napkins, panty liners, menstrual pants, baby diapers (cloths), adult diapers, disposable mattresses, nursing pads, disposable feminine menstrual tampons and other disposable incontinence products, and the like, so as to solve the problem that when pectin aqueous solution is used as a skin nursing agent in the existing absorbent article, water in the existing absorbent article can be absorbed by water-absorbing substances in the absorbent article, so that the performance quality of the absorbent article is seriously affected, and even the effect of the absorbent article cannot be achieved.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
an absorbent article comprising a contact surface for contacting human skin, said contact surface being coated with a skin care agent, said skin care agent comprising an aqueous pectin solution, characterized in that said skin care agent further comprises an oiliness agent coating said aqueous pectin solution, wherein the pectin is present in said aqueous pectin solution in an amount of 1.1 to 10.5%; the pectin aqueous solution accounts for 45-75% of the skin care agent, and the rest is oily agent.
The content of pectin in the pectin aqueous solution is 1.5-8%.
The pectin content in the pectin aqueous solution is 2-5%.
The pectin aqueous solution accounts for 60-70% of the skin care agent.
The oiliness agent comprises animal and vegetable wax/oil, mineral wax/oil and humectant.
The oiliness agent also comprises low-carbon alcohol, functional additives, preservatives and antioxidants.
The oily agent also comprises deodorant for decomposing urine and feces.
After the technical scheme is adopted, the skin care agent also comprises an oiliness agent for coating the pectin aqueous solution, wherein the content of pectin in the pectin aqueous solution is 1.1-10.5%; the pectin aqueous solution accounts for 45-75% of the skin care agent, and the rest is oily agent. The aqueous pectin solution and the oily agent water emulsion coating the aqueous pectin solution are blended to form an emulsifier, no liquid water appears, and the water in the aqueous pectin solution cannot be absorbed by the water-absorbing substances in the absorbent articles, so that the problem that the performance quality of the absorbent product is seriously influenced or even the effect of the absorbent article cannot be achieved due to the fact that the water in the aqueous pectin solution is absorbed by the water-absorbing substances in the absorbent articles when the aqueous pectin solution is used as a skin care agent in the existing absorbent articles is solved.

Example 21:
a baby diaper comprises a contact surface contacting with human skin, and skin care agent coated on the contact surface, wherein the skin care agent comprises pectin aqueous solution and oiliness agent, the proportion of pectin aqueous solution is 75%, and the oiliness agent is 25%; the content of pectin in pectin aqueous solution is 10.5%; the pH value of the baby diaper is 3 before use, 4.5 after the first simulated human urine is used, 6.5 after the second simulated human urine is used, and 6.5 after the third simulated human urine is used, so that the skin care effect is good.
In the above embodiment, the oily agent may comprise 3-7% of animal and vegetable waxes and oils, 8-15% of mineral waxes and oils, 1-3% of humectant, 35-70% of water, 1-3% of low carbon alcohol, 0.5-0.7% of other functional additives, 0.1-0.3% of preservative, 0.3-0.5% of antioxidant, and 0.2-0.5% of deodorant for decomposing urine and stool.
The skin care agent also comprises an oiliness agent for coating the pectin aqueous solution, wherein the content of pectin in the pectin aqueous solution is 1.1-10.5%; the pectin aqueous solution accounts for 45-75% of the skin care agent, and the rest is oily agent. The aqueous pectin solution and the oily agent water emulsion coating the aqueous pectin solution are blended, oil molecules wrap water molecules to form a stable substance structure, an emulsifier is formed, no liquid water appears, and the water in the aqueous pectin solution cannot be absorbed by the water absorbing substances in the absorbent article, so that the problem that the performance quality of the absorbent product is seriously influenced or the effect of the absorbent article cannot be achieved due to the fact that the water in the aqueous pectin solution is absorbed by the water absorbing substances in the absorbent article when the aqueous pectin solution is used as a skin care agent in the existing absorbent article is solved. Moreover, because the content of the pectin aqueous solution is 1.1-10.5%, a weak acid protective film coating is generated when the pectin aqueous solution contacts with a human body, and the functions of moisturizing, effectively preventing and repairing allergic eczema of the skin of the human body and the like can be realized. At this time, the skin care agent has good stability, stable chemical properties, excellent functionality, and excellent weak acidic effect, can form a layer of weak acid protective film on the surface layer of the skin by active or passive smearing or friction, so that the bacteria can not realize the environment of reproduction and growth, fully achieve and realize broad-spectrum bacteriostasis and balance the pH value of the surface of the skin, and simultaneously have the functions of moistening the skin, thereby preventing and repairing skin allergic eczema, ulcer, bedsore and other skin problems, when the specific gravity of the pectin is larger, the stronger the weak acid balance of the composition, the more rapid and long-lasting control effect can be satisfied, and when it exceeds 10%, a saturated solution is hardly formed, and when the specific gravity of pectin is less than or equal to 1%, the weak acid balancing capacity of the composition is such that there is little appreciable functionality in the end product when it is used, i.e. the rapidity and longevity of the balancing function is weak.
The skin care agent is not an aqueous solution or a pure oily solvent, but is an aqueous emulsion blended emulsifier formula, can meet the production and technical requirements of disposable products in the aspect of disposable sanitation or medical treatment, does not have the influence, obstruction and safety standard of moisture on the product quality or the production process, and basically and completely covers the skin health requirements of normal people. The emulsion formula of the invention achieves the technical requirement of practical application by improving the specific gravity of pectin and reducing the spraying or application dosage of unit products. For example, a total amount of about 1.6 grams of emulsion per unit of product is required for a specific gravity of 2.5%, and a total amount of about 0.46 grams is required for a specific gravity of 8%. The pH value can be controlled to meet the requirement of repeatedly long-acting and rapidly and instantly balancing the pH value of the skin for 2 times or even more. When the specific gravity of the pectin is 1% or less, under the condition of the same dosage or spraying amount, the pH value and the capability of treating acid-base balance degree which can be achieved by the pectin are relatively low, and the effect of long-acting for many times is obviously insufficient, and if the traditional disposable sanitary products, such as the Chinese baby diaper (diaper), are taken as an example, at least 5 g of pectin aqueous solution can only ensure the effect of controlling the pH within 6.0 for 2-3 times. If 1 g of the emulsion is sprayed on a medium baby diaper or a diaper, 2.5 percent of the emulsion can meet or achieve the effect of 2 times or more, and 8 percent of the emulsion can achieve the effect of at least 8 times or more. All stool or urine tests were based on actual use of infants in China and east Asia and southeast Asia. However, because of the aqueous solution, the disposable sanitary product and the government do not allow the production environment process, and the technical level of instantly drying or volatilizing the moisture is not reached. Therefore, for some industries such as disposable sanitary products, this is only a theoretical technique and cannot be practically applied.
