Problems solved by technology

It requires long periods of storing the pasteurized cosmetic at freezing temperatures; (ii) Pasteurization is not a sterilization method.
Handling pasteurized products requires extreme care; (iii) Maintenance of the pasteurization effect is also very difficult.
Hence pasteurization alone may not be enough to prolong the shelf life of cosmetic formulations.

Abstract

Disclosed is a novel method for preserving cosmetic/personal care formulations through a two component preservative system, said system comprising (a) Component I which functions to eliminate the existing microbial contamination load in a natural cosmetic formulation base through an optimized pasteurization method that avoids deep freezing; and (b) Component II that includes the step of adding synergistic blends of fractionated essential oils, extracts and isolated compounds to the pre-pasteurized cosmetic base obtained through the method of component I, wherein the synergistic blends sustain the effects of pasteurization through anti-microbial and anti-oxidant effects, said anti-oxidant effects enhancing further the anti-microbial effects by virtue of inhibiting lipid per oxidation that facilitates the undue proliferation of microbe.

Description

[0001]This application is a non-provisional filing of provisional application No. 61 / 050,050 filed on May 2, 2008.FIELD OF THE INVENTION[0002]The invention in general relates to methods of preserving cosmetic / personal care formulations to enhance shelf life and stability. In particular, the present invention discloses a novel method of preserving cosmetic / personal care formulations through a two component preservative system, said system comprising (a) Component I which functions to get rid of the existing microbial load (contamination) in a natural cosmetic formulation base using an optimized pasteurization method that does not involve the step of deep freezing; and (b) Component II that includes the step of adding synergistic blends of fractionated essential oils, extracts and isolated compounds to the pre-pasteurized cosmetic base obtained through the method of component I, wherein the said synergistic blends sustain the effects of pasteurization through anti-microbial and anti-o...
