Significance of Viscosity
Viscosity is a crucial physical property that defines a fluid's resistance to flow, influencing various formulations. It plays a significant role in assessing the consistency and performance of substances such as gels, creams, and oils. Factors like temperature and formulation concentration can alter viscosity, thereby impacting application characteristics and effectiveness. Viscosity is essential for determining how easily a substance spreads, adheres to surfaces, and the rate of active ingredient release, making it vital in fields like pharmaceuticals and food science.

The concept of Viscosity in scientific sources
Viscosity is a fluid characteristic influencing oil movement in urine, honey thickness, liquid flow resistance in Masura ghrita quality, absorption rates of Vasti Dravya, and the oily consistency of Karpanpatru Taila linked to Kalka.
From: World Journal of Pharmaceutical Research
(1) The measure of a liquid's resistance to flow; higher viscosity formulations can increase drug contact time with the nasal mucosa, enhancing absorption.[1] (2) A measurement of a fluid's resistance to flow, determined at a controlled temperature using a cone and plate viscometer.[2] (3) A measure of a fluid's resistance to flow, affecting how long a drug remains in contact with the nasal mucosa.[3] (4) A measure of a fluid's resistance to flow, impacting its thickness and movement.[4] (5) The measure of a fluid's resistance to flow, expressed in centipoise (cp).[5]
From: International Ayurvedic Medical Journal
(1) A quantity that describes a fluid's resistance to flow, which affects the duration of contact between the formulation and the body.[6] (2) The measure of a fluid's resistance to flow, with Dashamoola Taila having a viscosity of 84.45.[7] (3) A measure of a syrup's thickness and flow, indicating how easily it can be dispensed, with differences noted between the two syrup formulations.[8] (4) The measure of the thickness or resistance to flow of the Madhutailika Basti formulation, influencing its stability and absorption characteristics.[9] (5) A measure of a fluid's resistance to flow, significant in assessing the texture and usability of oils.[10]
From: Journal of Ayurveda and Holistic Medicine
(1) A physical property of liquids that describes their resistance to flow, which is measured as part of the quality evaluation of Masura ghrita.[11] (2) A measure of the honey's thickness or resistance to flow, affected by its sugar and water content.[12] (3) A characteristic of fluids that influences the spreading and movement of oil in urine.[13]
From: AYU (Journal of Research in Ayurveda)
(1) A property of Vasti Dravya that affects its absorption; lower viscosity leads to quicker expulsion from the body.[14] (2) A property of Karpanpatru Taila indicating its thickness, linked to its oily consistency attributed to the presence of Kalka.[15]
From: Journal of Ayurveda and Integrative Medicine
(1) A measure of a fluid's resistance to flow, important for determining the application ease of topical formulations.[16]
