Solublizing agents for UV filters in cosmetic formulations

The present invention relates to the use of the compounds (A) corresponding to formula whereinRis hydrogen; a linear or branched C-Caliphatic hydrocarbon residue comprising 0, 1, 2 or 3 double bonds;Rindependently from each other are hydrogen; methyl; ethyl; &#x2014;OH; &#x2014;COOR; &#x2014;CH&#x2014;OH; and &#x2014;CH&#x2014;COOR;Ris hydrogen; or a linear or branched C-Caliphatic hydrocarbon residue comprising 0, 1, 2 or 3 double bonds;Rindependently from each other are hydrogen; methyl; ethyl; &#x2014;OH; &#x2014;COOR; &#x2014;CH&#x2014;OH; and &#x2014;CH&#x2014;COOR;Ris hydrogen; or a linear or branched C-Caliphatic hydrocarbon residue comprising 0, 1, 2 or 3 double bonds;n is at least 0.1 on average;m1 and m2 independently from each other are 0; or 1;with the proviso, that at least one of the radicals R, Ror Rrepresent a linear or branched C-Caliphatic hydrocarbon residue comprising 0, 1, 2 or 3 double bonds,as solubilizing agent for organic UV filters (B) selected from(B1) benzophenone derivatives;(B2) hydroxyphenyl triazine derivatives; and(B3) trianilino-s-triazine derivatives.

Solubilizing agents for UV filters in cosmetic formulations

Disclosed is the use of an insoluble or sparingly soluble micronized substance class which is not a cosmetic UV absorber and which is dispersed in the oil- or water-phase of a cosmetic or dermatological composition for the enhancement of light protecting action of this cosmetic or dermatological composition comprising at least one cosmetic UV filter which is soluble in the water- or oil-phase. The cosmetic preparation according to the invention shows a remarkable increase in SPF.

Light protecting-effective cosmetic or dermatological preparations

Use of benzotriazole derivatives of formula (1), wherein Ris C-Calkyl; CCalkoxy; C-Calkoxycarbonyl; C-Ccycloalkyl; C-Caryl; aralkyl; &#x2014;SOM; a radical of formula (1) Ris hydrogen; CCalkyl; CCalkoxy; halogen, preferably Cl; or hydroxy; Rand Rare each independently of the other hydrogen; or d-Calkyl; m is 1 or 2; n is O or 1; if m=1, Ris hydrogen; unsubstituted or phenyl-substituted d-C-Calkyl; or C-Caryl; if m=2, R2 is the direct bond; or &#x2014;(CH)&#x2014;; and p is 1 to 3; for enhancing the photostability of cosmetic or dermatologic compositions comprising at least one further organic UV absorber. 

Use of benzotriazole derivatives for photostabilisation

Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic compound which has a UV-Vis spectrum with a maximum from 380 to 420 nm; and (b) an anionic dispersing agent for protecting the human skin from browning and skin aging.
