An alkyl 3-oxoalkanoate, a process for preparation and use for the synthesis of fatty hydroxylated amino acids, fatty amino alcohols and ceramides.

Alkyl3-oxoalkanoates

The invention is characterized by the use in cosmetic compositions of one or more lipophilic derivatives of amino deoxyalditols corresponding to the general formula:

Cosmetics of lipophilic derivatives of amino deoxyalditols, cosmetic compositions containing them, and novel alkyl carbamates

This invention includes an alkyl 3-oxoalkanoate, and processes for its preparation and use for the synthesis of fatty hydroxylated amino acids, fatty amino alcohols and ceramides.

Alkyl 3-oxoalkanoate and process for the preparation thereof

The present invention concerns hydrofluorocarbon compound with formula (I):

Hydrofluorocarbon compounds and their use in cosmetic compositions

Use in cosmetics of lipophilic derivatives of amino deoxyalditols, cosmetic compositions containing them, and novel alkyl carbamates. The invention is characterized by the use in cosmetic compositions of one or more lipophilic derivatives of amino deoxyalditols corresponding to the general formula: ##STR1## in which: R.sup.1 is a saturated linear C.sub.14 -C.sub.40 aliphatic radical;

Lipophilic derivatives of amino deoxyalditols, cosmetic compositions

The ceramides according to the invention are compounds corresponding to the formula: ##STR1## in which: R.sub.1 is a C.sub.11 to C.sub.21 alkyl or alkenyl radical; R.sub.2 is a linear or branched C.sub.1 to C.sub.29 hydroxyalkyl radical or a C.sub.7 to C.sub.29 hydroxyaralkyl radical, these compounds being in the form of a racemic mixture of the erythro and threo diastereoisomers for the aminodiol part ##STR2## in erythro:threo ratios of from 85:15 to 20:80. Application to cosmetic and dermopharmaceutical compositions.

Ceramides, process for their preparation and their applications in

New compounds of formula (I): ##STR1## in which: R.sub.1 represents a C.sub.4 -C.sub.18 alkyl or alkylene radical, R.sub.2 represents a C.sub.2 -C.sub.16 alkyl or alkylene radical, R.sub.3 represents a hydrogen atom or a C.sub.1 -C.sub.6 alkyl radical, and A represents a non-ionic hydrophilic group, as well as a cosmetic composition containing these compounds and the use of such a cosmetic composition in hair treatment.

Alkyl N-(hydroxyalkyl) carbamates and their application in cosmetics,

The use of alkyl N-(hydroxyalkyl)carbamates in a cosmetic or pharmaceutical composition provided in the form of an aqueous lotion, a gel, an emulsion, a cream, a foam or a paste.

Method of providing surfactant properties to a cosmetic or

Fluorinated hydrocarbon compounds have formula (I):

Fluorinated hydrocarbon compounds, their use in cosmetic compositions,

The invention relates to new hydrocarbon compounds containing a fluorinated chain of formula I ##STR1## and to their process of preparation. The invention also relates to the use of these new compounds as thickening agents, in particular for non-aqueous media, such as cosmetic compositions, and to the cosmetic compositions containing them.

Fluorinated compounds and compositions comprising them

Cosmetic compositions containing hydrofluorocarbon compounds

Use of hydro- and fluorocarbon compounds in cosmetic compositions;

The ceramides according to the invention are compounds corresponding to the formula: ##STR1## in which: R.sub.1 is a C.sub.11 to C.sub.21 alkyl or alkenyl radical;

The use of natural or synthetic ceramides as agents for thickening a medium, particularly a non-aqueous medium, and a thickened medium containing such a thickening agent The medium thus thickened may be used in the cosmetic, pharmaceutical, paint, varnish, lubricant, combustible, and food industries.

Use of ceramides as thickeners
