is still suiTable for use in treating wounds on the skin. 
If a topical preparation has a pH range that does not 
match the pH of the skin, then the preparation has the 
potential to cause irritation and erythema to its users.  
Gel base viscosity was measured at a speed of 0.1 
rpm for 30 seconds. According to Indonesian 
National Standars 16-4399-1996, the standard 
viscosity value for gel preparations is 6000-50000 cP 
or 6-50 Pa.S. Viscosity measurement results for the 
entire formula, resulting in a value that is included in 
the standard that is 9000-10500 cP. The research of 
Srividya et al (2001) describes corbopol 940 as a gel 
forming agent oflaxacin antibacterial agent in 
combination with hydroxypropyl methylcellulose 
(Methocel E50LV) which acts as a viscosity 
enhancing agent. The formulation developed is a 
therapy that is effective, stable, non-irritating and 
provides continuous drug release over an 8 hour 
period.  
Sari's research (2016), aims to find out the right 
comparison between 940 carbohydrate gel base and 
hydroxypropyl methylcellulose (HPMC) on the 
stability of physical properties of extract gel and 
methanol fraction of kesum leaves with Simplex 
Lattice Design (SLD) method, there is no significant 
difference between the properties physical extract gel 
and methanol fraction of kesum leaves (Polygonum 
minus Huds.). 
5  CONCLUSIONS 
Based on the organoleptic test, the four formulas are 
semi solid, yellowish-white, thick and odorless. 
Homogeneity testing, homogeneous preparations but 
there are bubbles The higher the concentration of 
putat air (B. racemose) extract, the more bubbles as 
well as the color of the yellowish gel. This is also due 
to high saponin levels. The pH test shows it is ideal 
for topical preparations, which is between pH 6-6.2. 
The highest pH is found in formulas with a 
concentration of putat air (B. racemose) extract 1%. 
Viscosity measurement results for the entire formula, 
resulting in a value that is included in the standard that 
is 9000-10500 cP. Based on the physical essence, this 
gel preparation is still suiTable for treating wounds 
on the skin.
