Problems solved by technology

Tea polyphenol is also a potential odor control agent, which is known as an odor control agent in the field of disposable absorbent products, but its powder form, color, stability, cost and relatively narrow odor control range limits its use in absorbent articles
[0004] Zeolites are known in the art for odor control applications, but their odor control range and particle size limit their use in absorbent articles

Embodiment 1

[0033] Embodiment one is calculated by every part of 10g

[0034]

[0035] 1) Use commercially available FAU zeolite powder, with a silicon-aluminum ratio of 72, and add it to the adsorption column. The adsorption column has a height of 45cm, an inner diameter of 3cm, and a zeolite adsorbent loading capacity of 120g.

[0036] 2) Weigh 10g of tea leaves, add 100ml of deionized water, extract at 70°C for 1 hour, filter to remove insoluble impurities, extract 3 times, combine the extracts, concentrate to 5% tea polyphenols content; adjust the flow rate to stabilize at 5.5ml / min , through the adsorption column. Then use 1 to 1.5 times column volume of deionized water to elute and remove impurities, take out the adsorbent, and remove excess water by suction filtration to obtain tea polyphenol zeolite.

[0037] The tea polyphenol extract with a tea polyphenol concentration of 5 is absorbed by an adsorption column filled with zeolite, and the column bed diameter-to-height ratio ...

Embodiment 2

[0042] 10g per serving

[0043]

[0044] 1) Use commercially available FAU zeolite powder, with a silicon-aluminum ratio of 15, and add it to the adsorption column. The adsorption column has a height of 45cm, an inner diameter of 3cm, and a zeolite adsorbent loading capacity of 115g.

[0045]2) Weigh 100g of tea leaves, add 1500ml of deionized water, extract at 90°C for 2 hours, filter to remove insoluble impurities, extract twice, combine the extracts, concentrate to 2% tea polyphenols content; adjust the flow rate to stabilize at 10ml / min, through the adsorption column. Then use 1 to 1.5 times column volume of deionized water to elute and remove impurities, take out the adsorbent, and remove excess water by suction filtration to obtain tea polyphenol zeolite.

[0046] The tea polyphenol extract with a tea polyphenol concentration of 2 is absorbed by an adsorption column filled with zeolite, and the column bed diameter-to-height ratio H (zeolite filling height) / d (column...

Embodiment 3

[0050] Embodiment three is in every part of 10g:

[0051]

[0052] 1) Use commercially available FAU zeolite powder, with a silicon-aluminum ratio of 72, and add it to the adsorption column. The adsorption column has a height of 45cm, an inner diameter of 3cm, and a zeolite adsorbent loading capacity of 120g.

[0053] 2) Weigh 100g of tea leaves, add 2000ml of deionized water, extract at 80°C for 1.5h, filter to remove insoluble impurities, extract twice, combine the extracts, concentrate to 8% tea polyphenols content; adjust the flow rate to stabilize at 8ml / min , through the adsorption column. Then use 1 to 1.5 times column volume of deionized water to elute and remove impurities, take out the adsorbent, and remove excess water by suction filtration to obtain tea polyphenol zeolite.

[0054] The tea polyphenol extract with a tea polyphenol concentration of 8% is absorbed by an adsorption column filled with zeolite, and the column bed diameter-to-height ratio H (zeolite ...

Abstract

The invention provides a deodorizing composition for absorptive products, which comprises tea polyphenol zeolite, binding materials and odor control agent. The invention additionally provides a preparation method of the deodorizing composition for absorptive products. The preparation method comprises the following steps of: firstly extracting tea leaves in water to obtain extract, mixing the extract, and condensing the extract till the content of tea polyphenol in the extract is 0.1-10 percent; then absorbing the tea polyphenol through an absorbing column filled with zeolite to enrich the tea polyphenol to obtain the tea polyphenol zeolite, wherein the ratio of height to diameter (H / d) of a bed of a chromatographic column is 1:1 to 25:1; and finally mixing the tea polyphenol zeolite with the binding materials and the odor control agent to obtain the deodorizing composition for absorptive products. The deodorizing composition for absorptive products has the beneficial effects that the composition has a multi-dimensional odor control effect, an easy-to-treat application form is realized, and by adopting the zeolite for absorption, dust and online application losses during application for a reason that the traditional odor control agent is powder are avoided.

Description

technical field [0001] The invention relates to a deodorant composition and a preparation method thereof, in particular to a deodorant composition applied to absorbent products. Background technique [0002] Absorbent articles such as disposable diapers, sanitary napkins and the like are commonly used to absorb body fluids such as urine, feces, vaginal discharge, menstrual blood. In absorbing these fluids, absorbent articles contain a number of volatile compounds including fatty acids (such as isovaleric acid), sulfur-containing compounds (such as mercaptans and sulfides), ammonia, amines (such as triethylamine), ketones (such as 4 -heptanone), alcohols and aldehydes (decyl aldehyde), which cause unpleasant odors that can be emitted by these products during wear or disposal of absorbent articles. Once the fluid has been absorbed into the absorbent article, these compounds may be present in bodily fluids or evolved through chemical reactions and / or fluid degradation mechanis...
