EC number: 266-340-9 | CAS number: 66402-68-4 This category encompasses the various chemical substances manufactured in the production of ceramics. For purposes of this category, a ceramic is defined as a crystalline or partially crystalline, inorganic, non-metallic, usually opaque substance consisting principally of combinations of inorganic oxides of aluminum, calcium, chromium, iron, magnesium, silicon, titanium, or zirconium which conventionally is formed first by fusion or sintering at very high temperatures, then by cooling, generally resulting in a rigid, brittle monophase or multiphase structure. (Those ceramics which are produced by heating inorganic glass, thereby changing its physical structure from amorphous to crystalline but not its chemical identity are not included in this definition.) This category consists of chemical substances other than by-products or impurities which are formed during the production of various ceramics and concurrently incorporated into a ceramic mixture. Its composition may contain any one or a combination of these substances. Trace amounts of oxides and other substances may be present. The following representative elements are principally present as oxides but may also be present as borides, carbides, chlorides, fluorides, nitrides, silicides, or sulfides in multiple oxidation states, or in more complex compounds.@Aluminum@Lithium@Barium@Magnesium@Beryllium@Manganese@Boron@Phosphorus@Cadmium@Potassium@Calcium@Silicon@Carbon@Sodium@Cerium@Thorium@Cesium@Tin@Chromium@Titanium@Cobalt@Uranium@Copper@Yttrium@Hafnium@Zinc@Iron@Zirconium

Any other information on results incl. tables
Under the experimental conditions adopted, LSDF ® RG (Batch No.90121) was found to be not irritating for the skin of the rabbit.
Classification according to DSD (Directive No.67/548/EEC) and subsequent amendments and CLP (Regulation No.1272/2008) is not required.

- Executive summary:
Bouchard, A. (2010)
In a primary dermal irritation study, the skin irritation/corrosion potential of LDSF® RG (Batch No.90121) was tested. 0.5 g of the test substance was applied on the skin of 3 rabbits under semi-occlusive conditions for 3 minutes, 1 hour and 4 hours on the skin of the first animal and for 4 hours for the two other animals.
The application of the test item did not induce colouring of the application site and did not interfere with grading of any skin lesion.
Any cutaneous lesion was evaluated approximately one hour, 24, 48, and 72 hours.
No other cutaneous lesion was observed.
Under the experimental conditions adopted, the test item was found to be a non skin irritant.
On the basis of the results of the present study, classification according to DSD Directive No. 67/548/EEC and subsequent amendments and CLP regulation No. 1272/2008 is not required.
