The pigment may also be a pigment with special effects. The term “pigments with special effects” refers pigments that generally create a non-uniform colored appearance (characterized by a certain shade, a certain vivacity and a certain lightness) that changes as a function of the conditions of observation (light, temperature, observation angles, etc.). They thus contrast with colored pigments that afford a standard uniform opaque, semi-transparent or transparent shade.
Several types of pigment with special effects exist: those with a low refractive index, such as fluorescent, photochromic or thermochromic pigments, and those with a higher refractive index, such as nacres or glitter flakes.
Examples of pigments with special effects that may be mentioned include nacreous pigments such as titanium mica coated with an iron oxide, mica coated with an iron oxide, mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye especially of the abovementioned type, and also nacreous pigments based on bismuth oxychloride.

The filler may include a clay (such as kaolin, disteardimonium hectorite, or a combination thereof), which may include a swellable clay. By “swellable clay” it is meant a clay material that is capable of swelling in water. An example of a swellable clay are smectite clays. The crystal structure of the smectite group, is an octahedral alumina sheet between two tetrahedral silica sheets. In one notable embodiment, the swellable clay is bentonite. Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group, and is produced by in situ devitrification of volcanic ash. In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz. Bentonite has an ability to form thixotrophic gels with water, an ability to absorb large quantities of water. Variations in interstitial water and exchangeable cations in the interlayer space affect the properties of bentonite and thus the commercial uses of the different types of bentonite.
One notable swellable clay suitable for use in the cosmetic composition is BENTONE GEL® ISD V dispersion, commercially available from Elementis Specialties, East Windsor, New Jersey. BENTONE GEL® GTCC V dispersion is a dispersion of organically (disterammonium) modified hectorite in isododecane with added propylene carbonate.

A carbonate, such as propylene carbonate or calcium carbonate, may be present. If present, the carbonate may be present in an amount such that the ratio by weight of swellable clay to propylene carbonate is about 2:1 to about 5:1.
While in certain embodiments, certain fillers such as hydrophobic silica aerogels may be included. In certain other embodiments, the cosmetic compositions may be substantially free of hydrophobic silica aerogels. The cosmetic premix compositions may free or substantially free of hydrophobic silica aerogels.
Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized via a sol-gel process in liquid medium and then dried, usually by extraction of a supercritical fluid, the one most commonly used being supercritical CO2. This type of drying makes it possible to avoid shrinkage of the pores and of the material. The sol-gel process and the various drying processes are described in detail in Brinker C J., and Scherer G. W., Sol-Gel Science: New York: Academic Press, 1990. Silica aerogels, in general, have been disclosed in U.S. Pat. No. 9,320,689, the entire content of which is hereby incorporated by reference.
As hydrophobic silica aerogels that may be used in the invention, examples that may be mentioned include the aerogel sold under the name VM-2260 (INCI name: Silica silylate), by the company Dow Corning, the particles of which have a mean size of about 1000 microns and a specific surface area per unit of mass ranging from 600 to 800 m2/g.
Mention may also be made of the aerogels sold by the company Cabot under the references Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, ENOVA® Aerogel MT 1100 silica aerogel, ENOVA® Aerogel MT 1200 silica aerogel.
Use will be made more particularly of the aerogel sold under the name VM-2270 (INCI name: Silica silylate), by the company Dow Corning, the particles of which have a mean size ranging from 5-15 microns and a specific surface area per unit of mass ranging from 600 to 800 m2/g.
The silica aerogel particles if used can be used in the cosmetic compositions from 0.1% to about 8% by weight, preferably from about 0.1%, 0.2%, or 0.5% to about 0.5%, 1% 2% or 5% by weight, all weights based on the weight of the cosmetic composition.
The one or more additional materials may include one or more emulsifiers. As used herein, the term “emulsifier” refers to any substance or agent that aids in the formation of an emulsion. As used herein, the term “emulsion” refers to a generally stable and homogeneous mixture of two liquids that do not normally mix (i.e., they are immiscible between themselves), such as vegetable oil and water. Emulsions can be true colloids or less stable mixtures, which tend to separate in a short time. An emulsion can often be broken down (i.e. the liquids separated) by factors such as mechanical manipulation, chemical effects and/or time.
The emulsifier may be a surfactant. As used herein, the term “surfactant” refers to an amphiphilic molecule, i.e. a molecule that has two parts of different polarity, one generally being lipophilic (soluble or dispersible in an oily phase), and the other being hydrophilic (soluble or dispersible in water), and which is preferably capable of reducing the surface tension of water. Surfactants are characterized by their HLB (hydrophilic-lipophilic balance) value, the HLB being the ratio between the hydrophilic part and the lipophilic part in the molecule. The term “HLB” is well known to those skilled in the art and is described, for example, in “The HLB system. A time-saving guide to Emulsifier Selection” (published by ICI Americas Inc., 1984). For the emulsifying surfactants, the HLB generally ranges from 3 to 8 for the preparation of W/O emulsions and from 8 to 18 for the preparation of O/W emulsions. The HLB of the surfactant(s) used according to the invention may be determined via the Griffin method or the Davies method.
The emulsifier may comprise or consist of a polyester of polyglycerol having 2 to 10 glycerol units (such as polyglyceryl-6 polyricinoleate).
The emulsifier(s) may be present in a total amount of no more than 15% by weight of the cosmetic composition. The emulsifier(s) may be present in a total amount of no more than 10% by weight of the cosmetic composition. The emulsifier(s) may be present in a total amount of no more than 8% by weight of the cosmetic composition. The emulsifier(s) may be present in a total amount of no more than 7% by weight of the cosmetic composition.

According to other embodiments, the thickening agent may include a polysaccharide.
