For example, if an ion-exchanged carrageenan having a first TG and a first TM is mixed with a subject to no ion exchange carrageenan having a second TG and a second TM is greater than the first TG and first TM, respectively, the resulting carrageenan would be a third TG between the first and second TG and TM third would be between the first and second TM.

The TG and TM of the mixture resulting carrageenan refer to the ratio of the amounts of the two fractions of initial carrageenan. Similarly, the mixture of carrageenan may also have a content that is gelling cation content between the two fractions of initial carrageenan, based on the ratio of the two fractions initial carrageenan.

This is further illustrated in the Examples below. Controlling the ratio of the two fractions of initial carrageenan, you can control the properties of the mixture of carageenan. In exemplary embodiments, you can combine two or more carrageenans in solution or gel form. In another exemplary embodiment, the two or more carrageenans may ds individually treated and then mixing dry powders together in dry form. When preparing gels, the cations present in two or more fractions can be interchanged to form a mixture of carrageenans as described above.

Various exemplary embodiments provide a process for preparing a mixture including carrageenan extract ion exchanged. Con referencia a la FIG. Valve 20 may be any device able to control exgraccion distribution of flow from inlet passage 10 into two portions: For example, the valve 20 may be a dispensing valve or other extrafcion device.

The valve 20 can direct the second portion 25 to and extract in an exchanger 30 ion. In exemplary embodiments, the ion exchanger 30 houses an ion exchange material, such as an acid cation exchanger in sodium form. The amount of ion exchange material and the flow rate of fluid through the ion exchanger can determine the effectiveness of ion exchange procedure ie, the amount of ions exchanged.

As the second portion 25 of extract flows through the exchanger 30 ions, carrageenan of the second portion extract is contacted with the ion exchange material, reducing the content of gelling cations carrageenan to produce a second portion 35 extract ion exchanged. The second portion 35 extrwccion extract and ion exchanged first portion 22 of extract are in a connector The connector 40 may be any device capable of combining the second portion 35 of extract ion exchanged and the first portion 22 extract to produce a 45 mixture of carrageenan.

In exemplary embodiments, the carrageenan can be used ion-exchanged or a mixture including carrageenan in ion-exchanged gel freshener cold setting.

However, the heating provides a substantial loss of the fragrance used in the air freshener formulation as some of the material of fragrance evaporates during heating.

Carrageenan products of the exemplary embodiments can be adapted to dissolve at temperatures at or below room temperature, which eliminates the loss of fragrance. Once dissolved, the formulation of freshening liquid can be poured into the final container containing gelling cations as discussed above which together with the carrageenan form the gel network.

Such cations can be added directly to the container before filling the container with the air freshener formulation or added cations as a coating, extaccion as a coating film, wherein the extracicon is precoated. As cations diffuse into the air freshener formulation resting conditions, formulation freshener gel in a homogeneous gel.

In exemplary embodiments, the carrageenan can be used ion-exchanged or a mixture including carrageenan in ion-exchanged water in oil emulsions, such as those for use carrahenina food carrxgenina or personal care products.

Las emulsiones de agua en aceite se caracterizan por una fase carragneina continua en que se dispersa una fase extdaccion de gotitas de agua. The water in oil emulsions are characterized by a continuous oil phase in which a discontinuous phase of dispersed water droplets. In many cases it is desired that the emulsion water in oil to an oil in water is reversed at a specified temperature so that the emulsion releases its water soluble constituents.

An example is margarine, wherein the emulsion is inverted in the mouth to release aromas and water soluble salts. La gelatina es el estabilizante preferido de la fase acuosa, puesto que la gelatina asegura que la fase acuosa funda a la misma temperatura que la fase oleosa. Gelatin is the preferred stabilizer of the aqueous phase, since gelatin ensures that the aqueous phase melts at the same temperature as the exhraccion phase.

That temperature is about the temperature in the mouth and thus through saliva and mouth shear, the emulsion inverts to an oil in water and release carragenian and salt. Conventional carrageenan products can not form gels that melt at the mouth temperature but carrageenan products of the present invention can be adapted to do so.

With respect to personal care products, extracciob lotions skin care is produced as oil-in water, the aqueous phase is the continuous phase. Esto es desventajoso debido a que requiere el uso de conservantes en las formulaciones de lociones para el cuidado de la piel.

This is disadvantageous because it requires the use of preservatives in the formulations of lotions skin care. Hay un deseo de eliminar los conservantes en lociones para el cuidado de la piel, en particular conservantes del tipo parabeno, debido a que presentan alguna similitud con las hormonas.

There is a desire to eliminate preservatives in lotions skin care, in particular preservatives paraben type, because they have some similarity to hormones. The use of carrageenan products of the exemplary embodiments makes it possible carrageniba provide a lotion skin care in the form of an emulsion of water in oil.
