Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.

Personal care compositions comprising coated/treated metal silicate absorbent particles

Disclosed is a fluid cosmetic composition comprising a sebum-absorbing calcium silicate. These cosmetic compositions provide effective, long-lasting facial cosmetic coverage that is highly resistant to the sebum-caused deterioration that results in the discoloration and fading typically experienced by conventional cosmetic compositions after a sustained period of use. The cosmetic composition may be in the form of a cr&#xe9;me, lotion, gel, semi-solid, dispersion, suspension, foam, mousse or spray.

Cosmetic compositions comprising calcium silicates

Disclosed is an oral care composition comprising a calcium metasilicate having an aspect ratio (average major axial diameter/average minor axial diameter) of from about 1:1 to about 2.5:, and an oil absorption of from about 20 ml/100 g to about 220 ml/100 g. Also disclosed is an oral care composition comprising: a calcium metasilicate having an aspect ratio (average major axial diameter/average minor axial diameter) of from about 1:1 to about 2.5:, and an oil absorption of from about 20 ml/100 g to about 220 ml/100 g, a disintegration aid, an organoleptic enhancing agent, and an abrasive.

Oral care products comprising calcium metasilicates

Disclosed is calcium metasilicate having an aspect ratio (average major axial diameter/average minor axial diameter) of from about 1:1 to about 2.5:1, and an oil absorption of from about 20 ml/100 g to about 220 ml/100.

Calcium metasilicates and methods for making

An amorphous silicate pigment having a pore volume of at least about 4.0 ml/g as measured by mercury intrusion, a BET surface area of at least about 300 m,/g, and an Al,O,content of about 2.0-10.0 wt % is provided. The invention can be successfully used in recording media coatings, particularly coatings for recording media used in ink jet printing systems.

High surface area silicate pigment and method

Pigmented paper fibers of improved brightness and light scattering ability are produced by treating the pulp fibers with 0.1 to about 10 wt. % of a silica/alumina sulfate sol composition at a temperature of about 50 to 80.degree. C. and good agitation.
