Abstract:
Metal salts of monoalkyl phosphates of the following formula ##STR1## in which each R represents a saturated or unsaturated, linear or branched hydrocarbon group having from 8 to 32 carbon atoms, and M represents an alkaline earth metal or divalent transition metal.The metal salts are particularly suitable as cosmetic powders, fillers for resins, and lubricants, parting agents and pigment dispersants for polymeric compounds. When used as cosmetic powders, the metal salts improve spreadability, moistness, smoothness, adherence, transparency and covering power of cosmetics.Preparation process of the metal salts is also disclosed.
Abstract:
Compounds of the formula I ##STR1## where the individual radicals R are identical or different and are each hydrogen, an alkali metal, or ammonium which is unsubstituted or substituted by organic radicals, or are each C.sub.1 -C.sub.20 -alkyl or a polyoxyethylene radical which contains from 1 to 10 ethylene oxide units and whose terminal OH group may be etherified by an alcohol of 1 to 3 carbon atoms, are used as sun screen agents.
Abstract:
The invention is directed to a cosmetic product comprising a powder/oil dispersion having high levels of cosmetic powder. More particularly, it is directed to an antiperspirant where at least part of the powder content is an astringent, such as aluminum chlorhydrate. By using one or more cationic or nonionic surfactants in an oily vehicle, a highly concentrated, stable dispersion having relatively low viscosity and creamy consistency, with a dry, non-oily feel is obtained.
Abstract:
This invention is directed to a cosmetic deodorant composition comprising:(a) from about 0.1 to 5 percent by weight, based on the weight of the total composition, of aminobenzoic acid amides of the formula ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represent hydrogen, an alkyl of from 1 to 12 carbon atoms; a hydroxyalkyl of from 2 to 4 carbon atoms; an aryl; an aralkyl or carboxyalkyl with from 1 to 3 carbon atoms in the alkyl moiety; or an alkoxyalkyl with from 1 to 8 carbon atoms in the alkoxy moiety and from 1 to 3 carbon atoms in the alkyl moiety, or R.sup.1 and R.sup.2 together with the amide nitrogen form an optionally substituted heterocyclic ring; and(b) the remainder conventional cosmetic deodorant composition compounds.
Abstract:
A powdered compressed cosmetic material comprising a hydroxypropyl-etherified glycolipid ester represented by the general formula; ##STR1## wherein R.sup.1 represents a methyl group or a hydrogen atom, R.sup.2 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 11 to 15 when R.sup.1 is a methyl group, or R.sup.2 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 12 to 16 when R.sup.1 is a hydrogen atom, A represents the group ##STR2## R.sup.3 represents a saturated or unsaturated hydrocarbon group having carbon atoms of 1 to 20 or --(A).sub.h H, and a, b, c, d, e, f, g and h are integers, whose sum ranges from 1 to 6.
Abstract:
The method of lubricating or softening the skin comprising the application of cosmetic preparations such as ointments, salves, creams, lotions, bar soaps, and the like, that contain a durable dry lubricant, comprising perfluorocarbon resins, said lubricant being inert to human and animal skin tissue, nonagglomerative, and sized to fit smoothly within the crease lines of human and animal skin tissue.
Abstract:
A process for non-migrating deposit of a composition for making up at least one keratinous material, such as, for example, a lipstick or a foundation, comprising including in said a-composition for making up at least one keratinous material at least one liquid continuous fatty phase comprising at least one dyestuff and at least one structuring polymer chosen from polymers of the following formula (I): in which n is an integer which represents the number of amide units such that the number of ester groups present in said at least one structuring polymer ranges from 10% to 50% of the total number of all said ester groups and all said amide groups comprised in said at least one structuring polymer, R1, which are identical or different, are each chosen from alkyl groups having at least 4 carbon atoms and alkenyl groups having at least 4 carbon atoms, R2, which are identical or different, are each chosen from C4 to C42 hydrocarbon-based groups with the proviso that least 50% of R2 are chosen from C30 to C42 hydrocarbon-based groups, R3, which are identical or different, are each chosen from C2 to C36 hydrocarbon-based groups, and R4, which are identical or different, are each chosen from hydrogen and C1 to C10 alkyl groups with the proviso that at least 50% of all R4 are chosen from hydrogen, and methods for making up the at least one keratinous material using the same.
Abstract:
The use of a thermally irreversible photochromic coloring agent, selected in particular from compounds belonging to the diarylethene family and/or those belonging to the fulgide family, as a coloring agent in a cosmetic composition, and to cosmetic compositions comprising it.
Abstract:
A method of improving the photochromism of a photochromic compound by including the photochromic compound in a composition with at least one component capable of scavenging at least one vacant state of an energy band, corresponding to an electron vacancy, of the photochromic compound. In particular, the component may be selected from components having at least one hydroxyl group, preferably a plurality of hydroxyl groups.
Abstract:
The invention relates to a cosmetic composition in the form of a compact powder comprising a fatty phase and a pulverulent phase, said pulverulent phase comprising a first incompactible filler and at least a second filler which may be compactible or incompactible, these two fillers being of different types. The composition preferably has an internal porosity of greater than 2 m.sup.2 /g. The composition is obtained by preparing an oil-in-water type emulsion of the fatty phase in an aqueous phase, dispersing the pulverulent phase in the emulsion, casting the dispersion obtained in a mould, and freeze drying the dispersion.
