Definitions
- This invention is situated in the domestic field of application of chlorinated products: the example which will serve as an explanatory basis in our presentation is bleach or more precisely the powders of dichloroisocyanurate and trichloroisocyanurate which, dissolved in water, lead to the formation of hypochlorous acid and hypochlorite ions.
- hypochlorite ions resulting from the dissolution of chlorine and chlorinated products into powders are very widely used as an industrial or household maintenance product for disinfection and bleaching.
- chlorinated products have a characteristic, pungent odor, which for some is a sign of cleanliness and disinfection but which for others is considered very unpleasant.
- the production of scented products must therefore be considered as the basis of a commercial argumentation but also ecological likely to preserve the environment of users.
- microencapsulation already known in other sectors but recently applied to the production of a mixture of incompatible products.
- chlorinated isocyanurate molecules can produce, under various constraints (humidity, temperature, pressure), a release of chlorine gas having a strong oxidizing potential vis-à-vis the perfume molecules.
- the liquid perfume is made pulverulent by adsorption on atomized silica so as to obtain a powder loaded with 50% by weight of perfume.
- chlorinated isocyanurate tested is Sodium Dichloroisocyanurate containing 60% active chlorine.
- Lime scent blend Pine fragrance blend Sodium dichloroisocyanurate Weight percentage of the scented additive 5 10 30 5 10 30 0
- Temperature rise observed during brewing 13 ° C 16 ° C Thermal decomposition 9 ° C 14 ° C 21 ° C 2 ° C Disappearance of "active chlorine available" in the powder 3.85% 10.6% - 2.5% 4.8% 13.64% 0
- the rise in temperature is a reflection of the oxidation reaction between the available chlorine and the perfume.
- the heat that can be dissipated here in the environment for the 20 grams of mixture produced could not be dissipated on mixtures of larger tonnage and the self-ignition observed for 20 grams of powder containing 30% of perfumes could appear for concentrations below 10% of scented powder.
- the microencapsulation processes of perfumes consist in including droplets of perfumes in a gangue of products insulating them from chemical attacks by chlorine.
- the film-forming agents for encapsulation selected for the application of the process with chlorinated isocyanurates must have particular qualities of chemical resistance to chlorinated oxidants and an important emulsifying power for the perfumes selected in order to obtain good water-dispersibility.
- the size of the perfume droplets obtained will depend on the dispersion formed before the spray-drying phase during which the outer shell of the capsule will dry and harden to give the protective covering. The result of this operation is a dry powder of variable particle size composed of grains highly charged with perfume but not having large quantities of perfume on the external face.
- the products selected and tested for this application belong to the chemical class of polymerized sugars such as dextrins, cyclodextrins, starches (modified or not) or dextroprotein complexes.
- microcapsules produced with the dextrins and the modified starch are in the form of grains of variable shape, of size less than 100 microns giving a powder which is not very runny.
- the charges for liquid perfume on these products reach 50% by weight of the final mass of the powder.
