Alumina Magnesium Metasilicate
What Is It?
Silica, also called silicone dioxide, and Hydrated Silica are minerals. The Silica used in cosmetics and personal care products is amorphous Silica. This means that the Silica has no definite form. Crystalline silica, which has a specific arrangement of the atoms, is not used in cosmetics and personal care products.
Hydrated Silica has additional water atoms bound to Silica. Other silica compounds that may be used in cosmetic products include Alumina Magnesium Metasilicate, Aluminum Calcium Sodium Silicate, Aluminum Iron Silicates and Sodium Potassium Aluminum Silicate. Silica and Hydrated Silica are used in a wide range of cosmetics and personal care products including bath products, eye makeup, hair care products, makeup, nail care products, oral hygiene products and skin care products.
Why Is It Used?
The following functions have been reported for Silica and the related ingredients:
- Ingredients used for abrading, smoothing or polishing, such as emery or pumice.
- Silica, Hydrated Silica, Aluminum Iron Silicates Ingredients that have the capacity to absorb or soak up liquids.
- Silica, Hydrated Silica, Alumina Magnesium Metasilicate Ingredients or processing aids that prevent powdered or granular substances from forming clumps.
- Silica, Hydrated Silica Non-reactive, solid ingredients that are used to dilute other solids, or to increase the volume of a product.
- Silica, Hydrated Silica, Alumina Magnesium Metasilicate, Aluminum Calcium Sodium Silicate, Aluminum Iron Silicates, Sodium Potassium Aluminum Silicate Substances that reduce the clear or transparent appearance of cosmetic products. Some opacifying agents are used in skin make-up for hiding blemishes.
- Silica, Hydrated Silica Ingredients that polish the teeth, reduce oral odor, or otherwise cleanse or deodorize the teeth and mouth.
- Hydrated Silica Skin Conditioning Agent
- Hydrated Silica Suspending Agent
- Silica Viscosity Increasing Agent
- Hydrated Silica Viscosity Increasing Agent
- Alumina Magnesium Metasilicate
Silica is a compound composed of silicon and oxygen. The amorphous form is used in cosmetics and personal care products. Amorphous Silica includes fumed silica.
The Food and Drug Administration (FDA) permits Silica to be directly added to food as an anticaking agent. It is also permitted as an Indirect food additives are additives that may become part of the food in trace amounts due to its packaging, storage or other handling. For example, minute amounts of packaging substances may find their way into foods during storage. as a component of filters and polyester resins. Aluminum Calcium Sodium Silicate (as sodium calcium aluminosilicate, hydrated) is considered Generally Recognized as Safe (“GRAS” is an acronym for the phrase Generally Recognized As Safe. Under sections 201(s) and 409 of the Federal Food, Drug, and Cosmetic Act (the Act), any substance that is intentionally added to food is a food additive, that is subject to premarket review and approval by FDA, unless the substance is generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use, or unless the use of the substance is otherwise excluded from the definition of a food additive.) as anticaking agent in food.
The safety of Silica, Hydrated Silica, Alumina Magnesium Metasilicate, Aluminum Calcium Sodium Silicate, Aluminum Iron Silicates and Sodium Potassium Aluminum Silicate has been assessed by the The Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) Expert Panel.
The CIR Expert Panel evaluated the scientific data and concluded that these ingredients were safe as used in cosmetics and personal care products.
The CIR Expert Panel has also reviewed the safety of other silicate ingredient including Calcium Silicate, Potassium Silicate, Sodium Silicate and Zeolite. Please search this website for these ingredients for more information on their safety.
CIR Safety Review:
The CIR Expert Panel reveiwed data indicating that inhaling large doses of amorphous Silica can result in irritation of the respiratory tract. Once inhalation exposure to Silica stops, Silica is removed from the respiratory tract, and recovery is observed. Long-term oral exposure to Silica has not resulted in any adverse effects, including effects on reproduction and development. Amorphous Silica is not genotoxic or carcinogenic. When placed on the skin, Silica is not irritating, nor does it result in sensitization.
Based on the available data, the CIR Expert Panel concluded that Silica, Hydrated Silica, Alumina Magnesium Metasilicate, Aluminum Calcium Sodium Silicate, Aluminum Iron Silicates and Sodium Potassium Aluminum Silicate were safe as used in cosmetics and personal care products.
Link to Code of Federal Regulations for Silica and silica compounds
Silica, Hydrated Silica, Alumina Magnesium Metasilicate, Aluminum Calcium Sodium Silicate, Aluminum Iron Silicates and Sodium Potassium Aluminum Silicate may be used in cosmetics and personal care products marketed in Europe according to the Under the general provisions of the cosmetics regulation of the EU, ingredients appearing on the following function-specific annexes must comply with the listed restrictions and/or specifications: colorants (Annex IV), preservatives (Annex V), UV filters (Annex VI) and other ingredients with specific concentration limits and/or other restrictions (Annex III). Ingredients specifically prohibited from use in cosmetic products are listed in Annex II. Other ingredients listed in the EU cosmetic ingredient database (CosIng) may be used without restrictions..
More Scientific Information
Silica can absorb moisture from the air. Therefore, packets of Silica are often kept with items that must be kept in a low moisture environment. A common use of Silica in cosmetics and personal care products is as an abrasive. Abrasives are used in cosmetics to remove unwanted cells or foreign materials from various body surfaces.
The removed materials may include dead skin surface cells, A soft tissue that forms over a cut or an injury to a plant surface, or a localized thickening of the skin., or dental plaque. Generally, abrasives are irregular shaped fine or coarse solids. Harder abrasives include special forms of Hydrated Silica uses for tooth cleansing, while softer abrasives, such as oatmeal are used to remove dead skin surface cells.
