Therefore, the substance zirconia aluminosilicate refractory ceramic fibres (SiO 2, Al 2 O 3, ZrO 2) as described in this document are a subset of the group of substances which are defined by the refractory ceramic fibres in Annex VI of the Regulation (EC) No 1272/2008.
Used as: anti-caking agent, anti-foaming agent, moisture absorbent, wine and beer fining agent. Definition: Composed of only silicon and oxygen, silicon dioxide is one of the most common anti-caking agents. It is also widely used in the construction and hydraulic fracturing (fracking) industries.uber Engineered Materials. Shanxi Jinjin Chemical Industrial Co., Ltd. wrote that âThere are no animal ingredients in the silicon dioxide.â. Yianlid Industrial Co., Ltd. said in an email that ââ¦There is not any animal content in the [silicon dioxide]â and sent a certificate analysis for silicon dioxide.
