1 Kg Fumed Hydrophilic Silica

Product number: RMMN1KFUMHYDPHISIL
AU$66.00

Product Description


Ingredients: Silica

 

A rheology control particle, an absorbent; an anticaking agent; a bulking agent; an opacifying agent; a non-surfactant suspending agent.

Appearance: Super Fine white powder with high potential for becoming airborne, wear PPE when handling and avoid inhalation.

Origin:  Nature Identical. Mineral.

While Silica is naturally occurring mineral, in nature it is found bound up in forms that make it unsuitable for direct cosmetic application.  Silica is most commonly found in Sand and in the soil as the crystalline mineral Quartz.  Silica in the soil is utilised by plants as mono silicic acids to help them improve their drought tolerance and strength.   This silica is transferred to animals (including humans) when we eat the plants and here it helps with collagen production and general growth and development.  As the silica is Quartz is impossible to separate out sand (a rich source of silica) is put through several processing steps that result in the silica (Silicon Dioxide) that we are talking about here.  As the resulting chemical is a pure form of what can be found in nature it is listed as 'nature identical'.

Many grades of silica exist for the cosmetic chemist to use. When these particles are made they cool to form chained aggregates rather than perfect spheres, this gives them superior thickening power over our other type of silica.  Additionally, the presence of hydroxyl groups (-OH) at the surface of the silica mean it is water wettable.  This is not the case for all silica particles.

Solubility: Water wettable but does not dissolve, dispersible in emulsions, oil swelling/ thickening.

Average Particle Size: This type of silica forms aggregates with an average particle size (BET Surface Area) of around 200m2/g

pH of dispersed particles in water: 3.7-4.5

Applications: Silica is useful to increase the viscosity of water-in-oil emulsions, pigmented products, dispersions and other complex mixtures. A higher than 3% level will overcome the "greasy feeling" to leave a "dry skin feel". Silica contained in foundation will absorb sweat and oils from the skin which helps the applied makeup last longer on the skin and also reduces light reflection. Silica improves the smoothness and spreading of foundations and creams.
