Definitions
- the subject of the present invention is the use of silica as an agent controlling the thermal degradation of alkali metal, alkaline earth metal or ammonium bicarbonate, as well as the use of the silica / bicarbonate mixtures thus obtained in cosmetic and detergency applications.
- 100 ⁇ m are well-known constituent elements of cosmetic and detergent formulations, in particular because of their abrasive properties, for controlling pH.
- thermal degradation is meant more particularly the temperature at which carbon dioxide is released.
- the usual temperature for mixing is of the order of 50 ° C. in order to avoid any degradation of the bicarbonate which they contain. Now it would be advantageous if this temperature could be raised so as to ensure improved productivity of the process for formulating toothpaste.
- bicarbonate has another drawback related to its very high ability to caking, aptitude all the more marked as the particle size is fine. This poses problems in particular when using said bicarbonate after more or less long storage. It is therefore necessary to be able to have a bicarbonate having better storage stability.
- bicarbonate can be stabilized when it is mixed with silica, not only during storage, but also during use.
- the bicarbonate thus additivated has improved flowability compared to bicarbonate alone, as well as a reduced ability to clot.
- the temperature range at which the bicarbonate is degraded that is to say the temperature range in which there is a departure of carbon dioxide, is shifted to higher temperatures and the range is widened.
- the mixture according to the invention has the advantage of being able to be used directly by the user.
- the composition of the mixture according to the invention is indeed compatible with applications in cosmetics and detergency in particular, such as for example the formulation of toothpastes. This allows the applicator to dispense with an additional step of dosing bicarbonate and silica, while having a mixture which does not have the drawbacks of bicarbonate alone.
- the first objective of the invention is therefore to thermally stabilize the bicarbonate of fine particle size.
- the bicarbonate can be an alkali metal, alkaline earth metal, or even ammonium bicarbonate. More particularly, the stabilized bicarbonate is an alkali or alkaline earth metal bicarbonate. Preferably, the bicarbonate is sodium bicarbonate. The average size of the bicarbonate particles is less than or equal to 100 ⁇ m.
- the average size of the bicarbonate particles is between 10 and 90 ⁇ m. More particularly, the average size of the bicarbonate particles is between 20 and 80 ⁇ m and preferably between 20 and 60 ⁇ m.
- the particle size is measured using an AFNOR sieve or by laser diffraction using a SYMPATEC granulometer
- Bicarbonate is generally obtained by implementing a process essentially comprising two parts.
- alkali metal carbonate, alkaline earth metal or ammonium is prepared, according to the Solvay process for example.
- an aqueous solution is prepared by dissolving the carbonate thus obtained and then carbon dioxide is injected to obtain the bicarbonate.
- the bicarbonates sold are suitable for the present invention.
- the present invention is particularly advantageous for stabilizing bicarbonates of extra-fine particle size.
- Silica will now be described.
- a precipitated silica is used.

- the pH used is basic, neutral or slightly acidic.
- the method of preparation of the silica can be any, such as for example consisting of the addition of acid on a silicate base stock or the total or partial simultaneous addition of acid or silicate on a base stock water or silicate solution, for example. It is possible to use in the present invention abrasive or thickening grade silicas. It should be noted that the quality of the silica is, conventionally, dependent on the conditions under which the precipitation is carried out.
- the silica used is of abrasive quality.
- silicas which have subsequently undergone a calcination step at high temperature, for example greater than or equal to 450 ° C.
- the silica used as a bicarbonate stabilizer has an average particle size of between 8 and 30 ⁇ m.
- the average particle size is between 8 and 25 ⁇ m and preferably between 10 and 20 ⁇ m.
- the average particle size is generally determined by laser diffraction on a SYMPATEC granulometer.
- the precipitated silicas used in the present invention preferably have a BET specific surface of between 140 and 300 m / g, in particular between 210 and 250 m 2 / g.
- the BET specific surface is determined according to the BRUNAUER-EMMET-TELLER method described in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938 and corresponding to standard ISO 5764/1 (annex I).
- the silica used in the present invention preferably has a DOP oil intake of between 250 and 370 ml / 100 g, in particular between 300 and 350 ml / 100 g.
- the DOP oil intake is determined according to ISO standard 787/5 using dioctylphthalate.
- a silica is used whose total pore volume is greater than 2.10 cm 3 / g. In general, the total pore volume is less than 5 cm 3 / g.
- the pore volume can be measured by mercury porosimetry.
- the silica used in the present invention usually has a pH of between 6.8 and 7.5.
- the pH is measured according to ISO standard 787/9 (pH of a 5% suspension in water).
- the amount of silica used is more precisely between 0.1 and 15% by weight relative to the weight of bicarbonate. More particularly, the amount of silica varies between 1 and 12% by weight. It is preferably between 2 and 10% by weight, and according to an even more particular mode, between 4 and 10% by weight.
- the contacting of silica and bicarbonate can be carried out quite advantageously, by a simple dry mixing of the two products. Any type of mixer is used insofar as it makes it possible to obtain a homogeneous distribution of the silica within the bicarbonate. Preferably, a mixer with double ribbon is used.
- the mixture comprising the bicarbonate stabilizes according to the invention, and more particularly the bicarbonate of extra-fine quality, exhibits instantaneous flowability such that the index i is at least 7, and preferably at least 8.5.
- Such an index is characteristic of a product which flows easily (i between 4 and 10)
- the same non-additive bicarbonate has an index i of approximately 5.5
- index i we denote the ratio of the main stress or the maximum stress that can be reached during the steady flow ( ⁇ i) to the resistance to compression of the product (fc) It should also be noted that these flowability measurements are carried out in a shear cell such as the JENIKE cell.
- the mixture having these instantaneous flowability indices comprises a bicarbonate additivated by 2 to 10% by weight of silica relative to the weight of bicarbonate and preferably by 4 to 10% by weight silica compared to the same reference.
- the mixture comprising the bicarbonate treated according to the invention, and more particularly the bicarbonate of extra-fine quality has a flowability after storage for 7 days, of at least 3 and can even reach 4.5, which class baking additive according to the invention among cohesive products, or even products flowing easily.

- the stabilized bicarbonate according to the invention is more particularly an alkali or alkaline earth meta bicarbonate, the former being preferred.
- the present invention is particularly suitable for stabilizing sodium bicarbonate.
- the average size of the bicarbonate particles is between 10 and 90 .mu.m More particularly, the average size of the bicarbonate particles is between 20 and 80 .mu.m and preferably between 20 and 60 .mu.m

- the silica content varies between 1 and 12% by weight relative to the weight of bicarbonate. It is preferably between 2 and 10% by weight, and according to an even more particular mode, between 4 and 10% by weight.
- the characteristics of this mixture such as instantaneous flowability, flowability after storage at 7 days and the thermal degradation properties of the bicarbonate it contains have been explained previously and will not be repeated in this section. It is completely surprising that the use of silica in this very specific range of quantity makes it possible to achieve the objectives of thermal stabilization, increase in flowability and resistance to caking, of a bicarbonate whose average particle size is very fine, which is a character which significantly aggravates the drawbacks of bicarbonate.
