Pickering emulsions, which are finely disperse systems of the water-in-oil or oil-in-water type, comprising (1) an oil phase, (2) a water phase, (3) at least one type of microfine particles which a) have an average particle size of less than 200 nm, which b) display both hydrophilic and lipophilic properties, i.e. which have amphiphilic character, and are dispersible both in water and in oil and which c) have optionally been coated on the surface, (4) at least one cyclodextrin and (5) at most 0.5% by weight of one or more emulsifiers.
摘要:
The present invention is related to compositions containing chitosan conjugated CLA (conjugated linoleic acid) and a chitosan conjugated Vitamin A or a null-cyclodextrin conjugated vitamin A. The invention also concerns the preparation of the compositions. The compositions according to the invention can be used as topical and cosmetic compositions as well as pharmaceutical compositions for treatment of atopical dermatitis, psoriasis eczema as well as eczema of different origins and solar dermatitis.
摘要:
Use of at least one agent chosen from cyclodextrins and the derivatives thereof as a pearlescent agent, in a composition, for example, a pearlescent cosmetic composition, comprising a physiologically acceptable aqueous medium. Use of at least one agent chosen from cyclodextrins and the derivatives thereof and at least one surfactant in compositions. Pearlescent compositions comprising, a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof, at least one surfactant, and at least one conditioning agent; as well as use of at least one agent chosen from cyclodextrins and the derivatives thereof as an agent for suspending an insoluble conditioning agent; wherein the compositions disclosed herein may be used in a form chosen, for example, from rinse-out products, for example, for washing and/or conditioning a keratinous material.
摘要:
Non-hydroxyalkylated cyclodextrins are disclosed wherein at least one primary alcohol function (CH2OH) is substituted, the nullOH portion being replaced by a substituent with formula nullOnullCOnullR or nullNR1R2, where: R, R1 and R2 independently represent a linear or cyclic, saturated or unsaturated, hydroxylated or non-hydroxylated alkyl group containing 1 to 30 carbon atoms, preferably 1 to 22 carbon atoms, more preferably a fatty chain containing 2 to 22 carbon atoms. These cyclodextrins are used as vectors for at least one active ingredient, in particular to encourage tissue penetration, in a cosmetic application, or for the production of pharmaceutical compositions, in particular dermopharmaceuticals.
摘要:
A complex of null-cyclodextrin or null-cyclodextrin and null-tocopherol is based upon null-cyclodextrin or null-cyclodextrin and null-tocopherol in a molar ratio of 2:1.
摘要:
An inclusion compound, which comprises a cyclodextrin or a branched cyclodextrin and a vanillyl alcohol derivative represented by the following formula (I) having been included therein: wherein, R represents a C1-6 alkyl group; and a composition containing the same. The inclusion compound exhibits remarkably reduce impure taste of VE and heightens its water solubility and stability. The inclusion compound considerably enhances and prolongs the pungent taste and warm-feeling imparting effect of VE per se and further increase and prolong the cool or refresh-feeling heightening effect of VE per se when used in combination with a refrigerant.
摘要:
The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy acids as teeth whitening/bleaching agents, particularly peroxyamidophthalamides together with hydrogen peroxide.
