| abstract |
An improved process for the preparation of cosmetic formulations containing a cosmetic active and a continuous phase comprising a water-immiscible liquid carrier, that are structured by a cyclo dipeptide (CDP) having the general formula in which R1 and/or R2, which may be the same or preferably different, each represents a hydrocarbon or alkylene ester group and the other may alternatively represent hydrogen,which employs a monohydric alcohol having a melting point of below 30oC and a boiling point of greater than 100oC and a cosmetic active material optionally together with at least one water-immiscible liquid carrier oil to assist in the dissolution of the structurant and modify the gelling temperature of the resultant mixture. Preferably, the CDP is dissolved in the monohydric alcohol and optionally up to half the water-immiscible oil prior to being mixed with the remaining ingredients of the composition. |
