EVALUATION OF pH AND VISCOSITY OF JUICE OF Zingiber officinale var. officinale MOUTHWASH FORMULATION

Abstract

Zingiber officinale var. officinale juice has many benefits. It can be used as a mixture of mouthwash. To analyse the difference of Zingiber officinale var. officinale mouthwashes 3,125%, 6,25%, and 12,5% on pH and viscosity values on day 0,14,28,42, and 56. Zingiber officinale var. officinale 3,125%, 6,25%, and 12,5% is mixed with propylene glycol, PEG-40 hydrogenated castor oil, oleum menthae, benzoic acid, sodium benzoate, calcium lactate, sorbitol 70% and calcium thiocyanate. The formulation has measured with pHmeter (Jenway, United Kingdom) and viscometer (Brookfield, Massachusetts) for 56 days. The pH data is analyzed using GLM Repeated Measures ANOVA and One-Way ANOVA (p<0,05). Viscosity data is analyzed using GLM Repeated Measured ANOVA and Kruskal Wallis (p<0,05). The pH value of 3,125% formulation shows significant difference for 56 days in range 5,50-5,61. The viscosity value shows no significant difference for 56 days in range 3,03-3,09 cP. The pH and viscosity values of 6,25% formulation shows no significantly different for 56 days with 5,78-5,83 pH value, while the viscosity is 3,12-3,13 cP. The pH and viscosity values of the 12,5% formulation shows no significantly different for 56 days with 4,90-4,97 pH value, while the viscosity is 3,43-3,50 cP. Zingiber officinale var. Officinale mouthwash formulations 3,125% has been unstable, but it has the lowest viscosity value and has been stabled for 56 days. The pH and viscosity values of 6,25% and 12,5% formulations have been stabled for 56 days. The highest pH value is in the formulation of 6,25%.
