[0085] The filler may include a clay (such as kaolin, disteardimonium hectorite, or a combination thereof), which may include a swelling clay. By "swelling clay" is meant a clay-like material capable of swelling in water. Smectite clays are an example of a swelling clay. The crystalline structure of the smectite group is an octahedral alumina sheet between two tetrahedral silica sheets. In a particular embodiment, the swelling clay is bentonite. Bentonite is a rock formed from highly colloidal and plastic clays composed primarily 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 the ability to form thixotropic gels with water, a capacity to absorb large amounts of water.Variations in pore water and exchangeable cations in the interlayer space affect the properties of bentonite and thus the commercial uses of different types of bentonite.

[0086] A notable swelling clay suitable for use in 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 modified hectorite (disterammonium) in isododecane with the addition of propylene carbonate.

The fillers may be present in the cosmetic compositions of the present invention in a total amount of at least 1% by weight.

[0088] 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 weight ratio of swelling clay to propylene carbonate is from about 2:1 to about 5:1.

[0089] While in some embodiments, certain fillers such as hydrophobic silica aerogels may be included. In some other embodiments, the cosmetic compositions may be substantially free of hydrophobic silica aerogels. The cosmetic premix compositions may be free or substantially free of hydrophobic silica aerogels.

[0090] Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are usually synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction of a supercritical fluid, the most commonly used being supercritical CO2. This type of drying avoids shrinkage of the pores and 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: Academie Press, 1990. Silica aerogels, in general, have been disclosed in U.S. Patent No. 9,320,689.

[0091] As hydrophobic silica aerogels which can be used in the invention, examples which can be mentioned include the aerogel marketed under the name VM-2260 (INCI name: Silica silylate), by the company Dow Corning, the particles of which have an average size of about 1000 qm and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0092] Mention may be made of the aerogels sold by the company Cabot under the references Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, silica aerogel ENOVA® AEROGEL MT 1100, silica aerogel ENOVA® AEROGEL MT 1200.

[0093] More particularly, the aerogel sold under the name VM-2270 (INCI name: Silica silylate), by the company Dow Corning, whose particles have an average size ranging from 5 to 15 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g, will be used.

[0094] The silica aerogel particles may be used in the cosmetic compositions in an amount of from 0.1% to about 8% by weight, preferably in an amount of from about 0.1%, 0.2% or 0.5% to about 0.5%, 1%, 2% or 5% by weight, all weights being based on the weight of the cosmetic composition. Emulsifiers

[0095] The one or more additional materials may include one or more emulsifiers. As used herein, the term "emulsifier" means any substance or any agent that helps form 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., are immiscible with each other), such as vegetable oil and water. Emulsions can be true colloids or less stable mixtures, which tend to separate within a short time. An emulsion can often break down (i.e., the liquids separate) through factors such as mechanical handling, chemical effects, and / or time.

[0096] The emulsifier may be a surfactant. As used herein, the term "surfactant" refers to an amphiphilic molecule, namely a molecule that has two parts of different polarity, one generally being lipophilic (soluble or dispersible in the oil 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, HLB being the ratio of the hydrophilic part to 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 emulsifying surfactants, 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 present invention can be determined via the Griffin method or the Davies method.

[0097] The emulsifier may comprise or consist of a polyglycerol polyester having 2 to 10 glycerol units (such as polyglyceryl-6 polyricinoleate).

[0098] The emulsifier(s) may be present in a total amount of not more than 15% by weight of the cosmetic composition. The emulsifier(s) may be present in a total amount of not more than 10% by weight of the cosmetic composition.

Some notable cellulose derivatives include hydroxyl-modified cellulose polymers such as hydroxyethylcellulose, for example, those having a molecular weight greater than 500,000 daltons such as NATROSOL ® 250 HHR hydroxyethylcellulose and hydroxypropylcellulose, for example, KLUCEL® MF hydroxypropyl cellulose - both available from Ashland of Covington, Ky.

[0102] According to other embodiments, the thickening agent may include a polysaccharide.
