Plan: The aim of current investigation to develop a novel cream formulation from essential oil of Acorus calamus and Hyptis suaveolence for the treatment of skin infection.
Preface: The delivery of pharmaceutical products through topical route is widely accepted for skin infection. So the development of topical formulation are designed to produced a systematic effect and benifical for the account of several advantages over other route of drug administration.
Methodology: Cream formulation consisting essential oil of Acorus calamus (Vach) and Hyptis suaveolence (Vilayati tulsi) was prepared and the formulation was subjected, microbial studies and In- vitro diffusion studies of formulation.
Result: The developed cream from essential oil was found to be safe and effective in skin infection

2. Chemical Composition
Suaveolens seed oil contained linoleic acid(76.13%),oleic acid(10.83%),palmitic acid(6.55%), stearic acid(4.56%) & heptacosanoic acid(1.94%) etc. As the major consituents.
Triethanolamine, Propyl paraben, Methyl Paeaben, Liquid Paraffin, purchased from Pure chem Laboratories, Dehradun
Steric acid Steric Acid was purchased from Vinayak Scientefic Industry,Dehradun& Hyptis suavelones entire plant was obtained from Ranipokhri,near Jolly grant (Dehradun) &Acorus calamus was collected from UIPS botanical garden
B. Preparation of Crèam Formulation
Preparation of Aqueous Phase: The water was heated to 65-70? C. Propylene glycol, terithanolamine, methyl paraben & propyl paraben were added and the temperature was maintained to 65-70? C.
Preparation of Oil Phase: White bee wax, stearic acid, stearyl alchol, cetyl alcohol were melted in a stainless steel vessel & to this mixture paraffin (liquid) was added and allowed to melt. The temperature of oil phase is maintained between 65-70? C.
C. Development of Cream Formulation
Oil portion was then slowly added to the aqueous phase while maintaining the temperature at 65-75 7 mixed for 10 to 15 minutes. When the addition of oil phase is done the solution is gradually dropped to 40 with continuous stirring and garlic oil is added. The obtained emulsion is then cooled to room temperature to form a semi-solid cream base. The pH of the crème base was kept between 4.5-6.

D. Evaluation Parameters
Take about 1gm of the crème in a clean petri dish and observe visually.
E. Physical Examination
The prepared topical crème were inspected visually for their colour, homogeneity, consistency spreadablity& phase separation. The pH of the crème is measured by using pH Paper.
F. Viscosity
The viscosity of the creme formulated is measured by “Brook field Viscometer LVD” using spindle S-94 At different speeds and shear rates. The viscosity determination is done at room temperature.
G. Tube Extrudability
Metage cream extruded from tube on application of finger pressure. The formulation is extruded in a clean collapsible aluminium tube of 5gm capacity with a nasal tip of 5mm opening. The extrudability was then determined by measuring the amount of crème extruded through the tip when pressure is applied from the finger.thod adopted for evaluating cream formulation was based upon the quantity in perc.
H. Micro Biological Studies
Microbiological testing is done by ‘Disk Diffusion Method’ by studying the out come of inhibition zone. In it the sample of active moiety from the antifungal creme is dropped in centre of culture of petri dish of culture of following colonies-
Staphylococci
Streptrococci
Yeast Mold.
The Inhibition zone is measured by ‘Zone Reader’
III. RESULT
Physical Evaluation: The creme obtained is Yellowish in color & Having a smooth texture. It is Homogenous with no sign of phase separation.
pH Measurement:The pH of the creme was found to be 6.2
Viscosity Measurement: It was found to be 67545 with Brook’s Field Viscometer.
A. Microbiological Studies
From the microbial study it was found that the cream showing good effect on microbial growth the zone of inhibition was calculated by zone reader. The zone of inhibition of candida albicans was 41.34 mm and E. Coli it was 33.23mm.
IV. DISCUSSION
From the above above compiled data the study clearly shows that the formulation is showing good in- vitro anti-fungal activity against E.coli & Candida albicans.
V. ACKNOWLEDGEMENT
I author wish to thank “Uttaranchal Institute of Pharmaceutical Sciences” for providing facilities and carry out research work & also Dr. Proff. Vikash Jhakhmola, Dr. Amit Semwal & Mr. Saraswati Prakash Bhatt for guiding me throughout my project tenor.
Conclusion
The formulation of Antifungal agents along with Hyptis suaveolones & Acorus calamus oil exhibited enhanced rate of diffusion and antifungal activity. The result of diffrent chemical and physical test of cream showed that it could use topically in order to protect against skin infection caused by fungus or bacteria.
