Hydrated Dental Silica ●
TL;DR. This ingredient is primarily used in toothpaste as an abrasive and polishing agent, helping remove plaque and surface stains. It can also help thicken gels and keep actives evenly suspended.
What does Hydrated Dental Silica do in a cosmetic formula?
This ingredient is primarily used in toothpaste as an abrasive and polishing agent, helping remove plaque and surface stains. It can also help thicken gels and keep actives evenly suspended.
Is Hydrated Dental Silica clean?
It is generally accepted in clean oral-care standards and is not a common sensitizer. The main quality variable is controlled particle size and abrasivity, since finished-toothpaste RDA should match the product’s use case.
Is Hydrated Dental Silica sustainable?
This material is mineral-derived and typically made by water-based precipitation from abundant inorganic feedstocks. It is not biodegradable in the biological sense, but it is inert, non-bioaccumulative, and has low persistence concern in normal rinse-off use.
Is Hydrated Dental Silica COSMOS-approved?
It is permitted under COSMOS natural and organic frameworks as an allowed mineral-origin ingredient, with no organic content contribution. From a Green Chemistry view, it aligns through abundant feedstocks, water-based processing, inertness, and low bioaccumulation potential, though it is not renewable.
How does Hydrated Dental Silica work chemically?
The molecule is an amorphous it inorganic oxide network with surface hydroxyl groups that bind water and influence viscosity, polishing strength, and compatibility with fluoride salts. In toothpastes, it is commonly used around 5% to 35%, with abrasivity governed more by particle size, porosity, and hardness than by concentration alone.
