PERSONAL CARE COMPOSITIONS AND METHOD FOR PREPARING THE SAME

Field of the Invention The present invention relates to personal care compositions and method for preparing the same. In particular, the present invention provides a personal care composition comprising extracts of organically certified herbs and organic essential oils, wherein the extract is prepared employing a super critical fluid extraction and water extraction. Background of the Invention

Various personal care products, like toners, mouthwashes, hand sanitizers etc. is prepared using ethyl alcohol to get transparent product and also keep the water insoluble ingredient solubilised. However due to stinging property and harsh nature of alcohol new water based transparent products are sold in the market. The solubilisers used in these products are generally ethoxylates and propoxylates like material. However these ingredients because of ethylene oxide used in manufacture can cause harm to consumer and environment.

Therefore, there is need to develop personal care compositions eliminates use of these types of solubilisers and provides improved formulations. Accordingly the present invention provides personal care compositions which avoids the drawback associated with the prior arts.
