Definitions
- the subject of the present invention is a composition comprising at least one alkaline or alkaline-earth fatty acid salt and a cellulose compound (preferably cellulose); the use of this composition to impart "whitening" properties to a film-forming composition intended for coating ingestible solid forms, more particularly, intended for the coloration of dry forms in the pharmaceutical industry, the preparation of food supplements and / or food and the veterinary field (capsules, tablets, pellets ).
- the invention also relates to the coating processes using said coating compositions and the colored coated products obtained by the implementation of the coating processes comprising the use of said coating compositions.
- compositions have the particularity of being free of titanium dioxide, a compound that is very widely used in these industrial fields, while retaining the covering and white coloring properties of dry forms, characteristic properties of titanium dioxide.
- Dry forms used in the human or veterinary pharmacy industries, and food supplements are generally in the form of tablets, capsules, dragees, granules, which are made by agglomeration of solid particles comprising at least one principle active ingredient and / or at least one nutritional ingredient and at least one excipient agent.
- These dry forms can be prepared by the implementation of many techniques known to those skilled in the art, such as compression techniques, pelletizing, granulation, compaction or extrusion.
- the coating compositions are well known to those skilled in the art and generally consist of at least one film-forming agent and of a dyeing system, consisting of pigments of mineral origin, such as, for example, iron oxides, or by dyes.
- Titanium dioxide ( ⁇ 2) is used in many applications (food additives - European Identification E171 cosmetics, pigments) for its ultraviolet absorption properties and its performance as a white dye.
- the purpose of the ANSES was to determine whether this study was "likely to call into question the conclusions of the EFSA (European Food Safety Authority) concerning the re-evaluation of the E171 published in September 2016", namely that "the available data on titanium dioxide (E171) in foods did not indicate a problem for the health of consumers ", while recommending the completion of additional studies.
