- the pasta of the invention because of their composition and their ability to adhere to the skin or mucous membranes of the mouth, can be advantageously used as a dressing and especially as a hemostatic dressing.
- Example 1 A paste according to the preferred embodiment of the invention is obtained by the following method. This process is carried out at room temperature.
- the first solution containing the food grade blue dye is introduced into the second solution and homogenized.
- the pH of the solution obtained is 2.
- Aerosil® 200 4.05 g of Aerosil® 200 are added to this solution and the mixture is mixed to obtain a gel.
- the aluminum chloride used as astringent agent used as astringent agent.
- the rheological behavior of the paste obtained in this example was measured using a flow test in which the dough sample is applied to a given deformation speed (shear rate) and the corresponding stress is measured and this, for increasing values of deformation rates.
- Test type flow with equilibrium measurements, with for each point:
- Range of shear rates 0.05 - 5 s "1 .
- Measuring geometry 25 mm anodized aluminum plane.
- Air gap 1200 microns.
- FIG. 1 shows the revolution of the viscosity of the paste as a function of the shear stress. This curve clearly shows the rheofluidifying behavior of the product, that is to say that its viscosity decreases with increasing shear rate.
- Example 1 To demonstrate the stability of this rheological behavior and to evaluate the effect of sedimentation of the pulp, a portion of the paste obtained in Example 1 was centrifuged and the bottom portion of the centrifuged sample collected. This lower part is subjected to the same flow test as previously described.
- Table II below groups the threshold stress values and the corresponding viscosities obtained in the paste of the invention after centrifugation.
- the thioxotropic character of the paste of the invention that is to say its ability to regain its initial viscosity (viscosity at rest) after loading, has been demonstrated using the following test carried out at 23 ° C.
- FIGS. 3 and 4 represent the evolution of the viscosity in time before and after solicitation.
- FIG. 3 represents the evolution of the viscosity at the second step of the test, ie with a "strong" shear of 5 s -1, which is seen in FIG. a bearing viscosity is quickly reached.
- Figure 4 shows the measurements made in steps 1 and 3 called low shear (0.05 s "1 ) and simulating the rest.
- the first step makes it possible to evaluate the viscosity at rest which is then between 3500 and 4000 Pa. s.
- the paper used has a grammage of 80 g / m 2 .
- the loop tack test involves contacting a paper tab on a sample and measuring the force required for peeling off the paper or tacking force.
- the contact area is 625 mm 2 (25 mm x 25 mm).
- This test does not involve pressure contact, that is to say that the loop is simply placed on the surface to be studied, unlike the needle tack tests where a holding pressure is applied on contact.
- the "loop tack" test does not make it possible to measure the adhesion strength: the measured adhesive force is of the order of the measurement noise. It can thus be said that in the case of simple contacting, without pressure, the paste of the invention has adhesive properties. The failure facies observed with the paste of the invention confirms this conclusion. Indeed, after detachment of the loop, a deposit of the paste of the invention remains on the latter. It should be noted that the measured value of the tack force can not be associated with this inevitable overweight of the loop, since the curve returns to zero (measurement noise after the peak of separation).
- the "tack" force is defined as the force required to separate a material having instant adhesion, i.e. by contact, of a surface that is to be adhered to.
- the rupture is cohesive, which means that the adhesion of the paste of the invention is greater than the cohesion. In these conditions, it is called tackiness.
- this weak cohesion is not detrimental to the intended application since the paste of the invention is used in thin layers on the skin or on the gingiva.
- the threshold constraint is then sufficiently important to prevent the volume of the product from flowing under the effect of gravity or blood flow.
- the paper used has a basis weight of 80 g / m 2 .
- the tack forces measured on the sample paste are grouped in the following Table IV:
- the high humidity of the environment causes water absorption by the dough of the invention which is then waterlogged.
- the dough of the invention still allows to obtain adhesion on the gum without application pressure.
- the ambient humidity of the mouth ultimately has little influence on the behavior of the dough since it does not have, during this short phase, the time to acclimatize to oral hygrometry.
- the adhesion properties of the paste of the invention have also been demonstrated by contact angle measurements.
- the aim is to measure the contact angles made by controlled liquid volume reference drops, here two microliters deposited on the surface of a given substrate, here the paste of Example 1.
- the angles are measured to the right and to the left of the drop for better accuracy and two seconds after the deposition of the drop.
- the reference liquids used are water and physiological saline, which gives results close to those obtained in the case of saliva and blood bathing the gum.
- Example 1 The paste of Example 1 was coated on a microscope slide until a satisfactory flatness was obtained. About 1 g of this paste was used, to obtain a film of about 1 mm thick and 10 cm 2 of surface, which corresponds to a basis weight of about 1 kg of pulp per m 2 of blade.
- the contact angle is measured on at least 5 samples of the reference liquids with the paste of Example 1.
- the measurement of the contact angle makes it possible to visualize the spreading of the reference liquids on the paste obtained in Example 1, that is to say the affinity of these liquids for the paste of Example 1. These measurements make it possible to have an idea of the affinity of the paste of Example 1 for liquids in contact with the gum, such as saliva and blood.
- the contact angle measured will be high because the sample seeks to minimize its contact surface with the substrate (paste of Example 1).
- a method of manufacturing a paste according to the invention does not contain aluminum chloride is given below.
- This process is carried out at room temperature. We weigh 45.55 g of water. 10 g of this water, in which 0.05 g of food-grade blue dye is dissolved.
- the paste of the invention has a stickiness which when used as a mechanical dressing on a wound of the skin or gum allows adhesion without pressure, which is an asset to guarantee the painlessness of the skin. operation and cleanliness of the wound after treatment, since no significant pressure has been exerted on it.
- the paste of the invention is very easily removed, painlessly.
