Description
Technical field
The present invention relates to a kind of absorbing products, particularly relate to a kind of absorbing products comprising tea polyphenols deodorant compositions.
Background technology
Such as disposable diaper, sanitary towel, etc. absorbing products be generally used for absorb body fluid, such as urine, feces, vaginal secretions, menses.When absorbing these fluids, absorbing products comprises many volatile compounds, it comprises fatty acid (such as isovaleric acid), sulfur-containing compound (such as mercaptan and sulfide), ammonia, amine (such as triethylamine), ketone (such as dipropyl ketone), alcohols and aldehydes (capraldehyde), and what they caused can being discharged by these products during absorbent article dress or when disposing makes us unhappy abnormal smells from the patient.Once fluid has absorbed in absorbent article, then these compounds can be present in body fluid or by chemical reaction and/or fluid degradation mechanism and formed gradually.In addition owing to contacting with microorganism and/or enzyme, described microorganism and/or enzyme also can generate cacodorous by-product due to mechanism such as such as corrupt degraded, acid degradation, protein degradation, fat acid decompositions.These abnormal smells from the patients can cause making the wearer of absorbent article and nurse unhappy.
As the prior art for removing this undesirable abnormal smells from the patient, as the deodorant such as silica gel or POLARGEL NF is directly flooded by Excreta, the occasion of porous deodorant, deodorant surface is covered by above-mentioned Excreta, deodorize function can not be given full play to, namely there is the problem that deodorising effect is low.As cyclodextrin has deodorization functions due to the odorous substance existed around the little enclose of granularity, but the compound under state before use due to the moisture cyclodextrin inclusion compound in air in air, cause deodorization functions to decline.And cyclodextrin is used alone and easily comes off from absorbent commodity.Deodorize function can not be given full play to, namely there is the problem that deodorising effect is low.In addition, use polymer as binding agent the powder of cyclodextrin to be fixed on situation on absorbent commodity although also disclose, absorbent commodity is hardening, has damaged its feel.
Although disclosed many sanitary towels with deodorant function in this area, but major part is all by non-woven fabrics soaking medicated liquid, then for sanitary towel, as Chinese patent application CN200820028805.7, there is infringement in this sanitary towel of life-time service to health, and deodorizing effect is not good.
Summary of the invention
The object of this invention is to provide a kind of absorbing products comprising tea polyphenols deodorant compositions.Abnormal flavour can be resisted with number of mechanisms, include but not limited to the molecular reaction producing abnormal smells from the patient and prevent stench from producing, thus there is the absorbing products of the abnormal smells from the patient control characteristic of wide spectrum.

Tea polyphenols is the general name of Catechin in Tea class (flavanol compound), flavonoid, phenolic acids and anthocyan compound, account for 15 ~ 25%. of dry weight of tea leaves in eighties of last century eighties, the research of tea polyphenols is developed, medicine, daily use chemicals, lightization, cosmetics, edible oil, oils and fats, health care etc. all many-sides have broad application prospects.In fact in tea polyphenols, most important composition is the multiple catechin of flavanol compound.With multiple activity hydroxy (-OH) in tea polyphenols molecule, can stop free chain reaction in human body, remove superoxide ion, the elimination factor of tea polyphenols to superoxide anion and Both peroxyl radical reaches more than 98%; Tea polyphenols cell membrane and cell wall have protective effect, fairly obvious to the eliminating effect of lipid peroxidation free radical, and tea polyphenols has inhibitory action widely to antibacterial; there is enhancing human body immunity ability, radioprotective, there is oxidation retardant Aging Mechanism; toxicologic study confirms, tea polyphenols is safe, nontoxic.Meanwhile, tea polyphenols has elimination effect to multiple abnormal flavour.Although tea polyphenols as one at the potential odor control agent of absorbing products tool, it is applied to disposable absorbent article field as odor control agent is known, but the abnormal smells from the patient span of control of its powder form, color and luster, stability, cost and relative narrower limits its application in absorbing products.
According to the present invention, absorbent device is by adopting any means well known in the art by each element as top flat, egative film are connected with absorbent article core.Such as, egative film and/or top flat can be connected to absorbent article core by the array of the line of the adhesive layer of the adhesive layer of uniformly continous, composition or discrete binding agent, helix or point and get angry and be connected with each other.Such as by heat bonding, pressure bonding, ultrasonic bonds, dynamic mechanically connection or any connected mode well known in the art and combination, each element can be connected.
By any method well known in the art, odour control particles can be attached in articles for use.Usual odour control particles is positioned at absorbent article core structure, such as, granule can on the core of absorbent device stratification or be blended in the fiber of absorbent article core.Odour control system is preferably clipped between two layers of sheet material.Optional, granule can with such as hotmelt or other suitable bonding system any are bonded between two layers of cellulose tissue layer.Binding agent is preferably also coated in laminated product edge guarantees product edges is connected to each other thus to make to be fixed on laminated product any loose
In absorbing products, the consumption of deodorant compositions depends on size and the character of the layer that said composition will add and absorbent article.Deodorant compositions consumption is normally at least greater than 0.005g/ sheet.Described absorbent sanitary product includes but not limited to sanitary towel, diaper, protective pad.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, control to need, have abnormal smells from the patient span of control wide for absorbing products abnormal smells from the patient.There is easy-to-handle application form, avoid the dust and application on site loss that occur in the powdered application of traditional odor control agent.By cyclodextrin inclusion compound tea polyphenols, enhance the stability of tea polyphenols, it also avoid the impact of tea polyphenols color and luster on absorbing products.Menstruating female uses this absorbent sanitary product to avoid unjoyful abnormal smells from the patient, can orthobiosis, work.
