Technical Field

The invention relates to the field of disposable hygienic products, in particular to a non-woven fabric chip with slow-release tea polyphenol.

Background

According to the published data, the following materials are available: the tea polyphenols have various physiological activities of resisting oxidation, preventing radiation, resisting aging, reducing blood lipid, reducing blood sugar, inhibiting bacteria and inhibiting enzyme, etc.

Tea polyphenol mostly contains more than 2 ortho hydroxyl polyphenols, and has strong hydrogen supply capability, so that the tea polyphenol is an ideal antioxidant. Of the 4 major catechins, antioxidant capacity is expressed as EGCG > EGC > ECG > EC. As an antioxidant of oil food, the antioxidant has excellent antioxidant performance and far better effect than artificially synthesized antioxidants of 2, 6-di-tert-butyl-4-methylphenol (BHT) and Butylated Hydroxyanisole (BHA). The tea polyphenol has antioxidant effect, and can be used for meat product processing, oil storage, and preparation of baked food, dairy products, and fried food, and also for preventing skin aging.

The tea polyphenol is led into the pores of the diatomite to play a role in slowly releasing the tea polyphenol, and if the tea polyphenol can be acted on the skin of a human body, the long-acting and stable anti-aging function can be achieved. The invention aims to develop a non-woven fabric chip with slow-release tea polyphenol, which can be widely applied to female sanitary towels and other products contacting with human skin.

Disclosure of Invention

The invention aims to solve the technical problem of developing a non-woven fabric chip with slow-release tea polyphenol, which slowly releases tea polyphenol in the using process, thereby having the long-acting and stable anti-aging function.

The non-woven fabric chip with the slow-release tea polyphenol is formed by uniformly coating a layer of diatomite-loaded tea polyphenol paste on a spunlace non-woven fabric. The paste adopts the following formula by weight percent: 5-20% of diatomite loaded with tea polyphenol, 1-10% of stearic acid, 1-10% of glycerol, 0.5-5% of lanolin, 1-10% of liquid paraffin, 0.2-2% of octadecanol, 0.5-5% of triethanolamine, 0.02-0.2% of methyl p-hydroxybenzoate and the balance of deionized water. The weight percentage of the paste coated on the spunlace non-woven fabric to the spunlace non-woven fabric is (10-30): (90 to 70)

The diatomite loaded with tea polyphenol is prepared by the following method.

Adding 50.2-73.1 parts of water into a stirring kettle, adding 0.5-2 parts of 5040 type dispersing agent, 0.1-0.4 part of wetting agent and 0.1-0.3 part of 208 type defoaming agent, uniformly stirring, continuously adding 2-5 parts of tea polyphenol into the stirring kettle according to a proportion, slowly dropwise adding 0.2-0.5 part of Kh-570 type silane coupling agent, and stirring at a high speed to uniformly disperse the materials.

And then adding 25-40 parts of diatomite into the stirring kettle in proportion to continue dispersing, and uniformly stirring at the speed of 1000-1500 rpm for 2-4 hours.

And finally, drying the obtained solution, crushing the obtained solid, and sieving the crushed solid by a 100-mesh sieve to obtain the diatomite loaded with the tea polyphenol.

The present invention has the following advantageous effects.

The diatomite has a large number of pores, tea polyphenol can permeate into the pores of the molecular sieve, and after drying, most of the tea polyphenol is left in the pores of the diatomite, and a small part of the tea polyphenol is attached to the surface of the diatomite. When the obtained material is made into daily necessities (such as sanitary towels, sanitary pads, underwear, underpants and the like) and is directly or indirectly contacted with the skin of a human body, the tea polyphenol attached to the surface of the diatomite can directly play a role in resisting aging. Secondly, sweat, skin or body secretion generated by the skin of a human body are easily absorbed into pores of the human body by the diatomite, so that the tea polyphenol in the pores of the diatomite is slowly dissolved out and utilized by the skin, and the anti-aging effect is achieved. And thirdly, because the diatomite is loaded with the tea polyphenol and plays a role in resisting aging for a human body in a transdermal absorption mode, the process is slow and relatively uniform, and the problems that the anti-aging rapidly rises to reach a peak value and then rapidly falls and the duration is short in the absence of a slow release function can be solved.

In order to verify that the invention reduces the toxic and side effects of the product, according to the disinfection technical specification, a New Zealand little rabbit is adopted to carry out a patch irritation test, the patch area is 2.5 centimeters by 2.5 centimeters, the test time is 1 hour, 24 hours and 48 hours, and the test results are shown in the following table.

Test results show that the non-woven fabric chip with the slow-release tea polyphenol has no irritation.

In order to verify the stable controlled speed of the tea polyphenol-loaded functional non-woven fabric, a new Zealand small white rabbit is adopted to carry out a patch absorption speed test, the patch area is 2.5 cm by 2.5 cm, the content of tea polyphenol in the non-woven fabric in the patch after 4 hours, 12 hours, 24 hours and 48 hours is tested, and the change of the release rate of the tea polyphenol is obtained through the change of the content of the residual tea polyphenol after the transdermal absorption of the tea polyphenol. The tea polyphenol content test method is HPLC (high performance liquid chromatography). Scheme A is the scheme of the invention. In the method of the scheme B, the diatomite is replaced by the liquid paraffin, and the viscosity is adjusted to be basically consistent with the scheme A.

The test results are given in the table below.

It can be seen from the above table that the release rate of tea polyphenol in the non-woven fabric of the scheme a is more stable. The absorption rate of the solution B is obviously not stable compared with the solution A because the absorption rate is fast at the beginning and slow at the back.
