Step 2
Dissolve or suspend all the benzalkonium chloride in a sufficient portion of the water to provide a pre-mix solution or suspension totaling 0.2% weight of final product.
Step 3
In a separate mixing vessel, add water totaling 90.8% weight of the final product.
Step 4
Separately add each of the premixes (described in steps 1 and 2) to the water of step 3, and blend.
Step 5
Add all the phenoxyethanol and ethylhexylglycerin to the contents of the mixing vessel, and blend.
Step 6
Add all the glycerin to the components in the mixing vessel, and blend.
Step 7
Mix well (for >10 minutes) until all the ingredients are homogenized.
Tests for Disinfectant Performance
Each formulation was tested to see how effective it was in killing germs. This included a quantitative suspension test to evaluate bactericidal activity according to the well-known European test standard EN 13727. The formulations were also tested for virucidal activity by the surface carrier technique of ASTM 1053. Additionally, each formulation was subjected to tests to determine its effectiveness at 24 hours after being applied to human skin (hands). The tests were carried out as follows.
Step 1 (Culture Growth)
Two test organisms were selected and evaluated in the trial:
• Staphylococcus aureus NZRM 147 (ATCC 6538)
• Escherichia coli NZRM 2577 (ATCC 8739)
Culture suspensions were prepared for the organisms using overnight culture plates. The culture growth was harvested from each plate and inoculated to 10mL Tryptone Soy Broth (TSB) to achieve an approximate organism count of 109 cfu/mL.
Step 2 (Chemical Inactivation)
A combination of neutraliser and dilution was used to achieve an effective neutralising system. In particular, Tryptone soy broth with 0.5% Lecithin and 4% Tween 20 (TLT) was used as a neutralising solution. Hand Sanitizer Formulation at ‘ready to use’ (RTU) concentration was diluted at a ratio of 1 :1000 (10pL in 10mL TLT, the same volume and dilution ratio as treated Vitro-skin 2cm2). 10mL of the diluted formulation was then individually spiked to give a cell level sufficient to render a test organism concentration within the countable range. In the presence of TLT the antimicrobial property of the test products was neutralized in order to recover any viable micro-organisms. The recovery of the test organism in the presence of test product was not less than 70% of that recovered from the inoculum control.
Step 3
In a Biological Safety Cabinet, two 2cm2 synthetic skin swatches were each pre-treated with 10pL of the test product at the RTU concentration. Each pair of skin swatches was rubbed together to distribute the test product, and dried under HEPA laminar air. The formulation remained on the swatches for sufficient time to demonstrate the residual efficacy of each test product. Duplicate tests were performed at each time point for all test products (including the reference product) and the water control.
Step 4 - (Water control - Baseline Control)
The synthetic skin swatches were also pre-treated with sterile water in the same manner as the test product, and tested at the same time points along-side the test product.
Step 5
At various time points, each treated skin swatch was inoculated with 10pL of culture suspension at an approximate concentration of 109 cfu/mL, and evenly distributed with a sterile 1 piL loop. An exposure time of 5 minutes was allowed prior to transferring the skin swatch into neutralising broth (TLT).
The inoculated neutralising broth was mixed and serially diluted to aid in determining the number of viable bacteria remaining.
Step 7
Step 5 and 6 were followed to test the water control in the same manner as the test product.
Step 8
The neutralised solutions for the test products and the water control were serially diluted using 0.1% Peptone, and each dilution was plated in duplicate using Standard Plate Count Agar.
Step 9
The plates were incubated at 35°C ± 1°C for 48 hours.
The tests gave the results detailed below.
Results
Quantitative Suspension test for evaluating bactericidal activity
Nv is the number of cells per ml in the validation suspension.
A, B and C are the numbers of surviving cells in the experimental conditions control (A), neutralizer control (B) and method validation (C), at the end of the contact time
A, B & C should preferably be >50% the value of Nv.
By way of summary, (TMD 110, EN13727), Formulations A and B showed greater than 6 log reduction against S.aureus, E.coli, P.aeruginosa and E.hirae at 1 minute contact time.
Formulation C showed greater than 6 log reduction against E.coli, P.aeruginosa and E.hirae and greater than 5 log reduction against S.aureus at 1 Minute contact time. All three formulas resulted in a >99.99% reduction in microorganisms after 1 minute contact.
Note:
Presence of virus is presented in a X+ of 4 format i.e. X+/4:
X+ - number of wells (X) with presence of virus (+)
4 - total number of inoculated wells.
Example: In the event of a 3+/4 result, this indicates that 3 of the total 4 wells show a positive virus response.
Absence of virus in each response is recorded as “0”
Cytotoxic response is recorded as “C”
Calculated virus titre = 106.77TCID50/0.1 ml (6.77 Iog10)
Cell control - 4 wells with healthy cell monolayer
* The Reed & Muench LD50 Method was used for determining the virus titre endpoint.
To summarise the results (TMCV 006, ASTM E1053), regarding cytotoxicity and neutralisation, the Formulations A and B showed virucidal efficacy against MHV1 by achieving 3.44 log reduction in virus concentration after 1 minute’s exposure period at room temperature. The formulations C also showed virucidal efficacy against MHV1 by achieving 3.10 log reduction in virus concentration after 1 minute’s exposure period at room temperature. This indicates that each formulation results in >99.9% reduction in viral count after 1 minute contact time, with Formulas A and B exhibiting slightly better results than Formula C.
Results
The 24-hour Residual Anti-Microbiological Study of the Hand Disinfectant Product Methodology: The above Custom In-vitro Study Protocol
By way of summary, Formulation B (at RTU volume) demonstrated residual efficacy with log reduction of between 2.27 and >6.57 throughout the 24 hour’s period (at 5 mins, 30 mins, 1 hr, 2hr, 4hr, 6hr and 24hr) against Staphylococcus aureus NZRM 147 and Escherichia coli NZRM 2577. In comparison, Formulations A and C did not exhibit effective residual efficacy against either bacterial strain (maximum log reduction for either organism did not exceed 0.2 at any time point).
Formulation B demonstrated residual biocidal activity against both Staphylococcus aureus and Escherichia coli after 24 hours (4.93 and 2.46 log reduction, respectively). This translates to a >99.99% and >99% reduction in the count of Staphylococcus aureus and Escherichia coli, even if exposure to either organism occurs 24 hours after application of Formula B. Conversely, Formulation A exhibited a low log reduction against Staphylococcus aureus (0.02) after 24 hours, in addition to exhibiting a negative log reduction against Escherichia coli (-0.10), indicating growth of organism. Similarly, Formula e resulted in negative log reductions against both Staphylococcus aureus (-0.04) and Escherichia coli (- 0.12) after 24 hours, indicating organism growth.
This is significant as it indicates that Formula B exhibits residual efficacy against microorganisms on synthetic skin, even after significant time has passed following application of the formula. This is believed to be related to a synergistic interaction provided by the Benzylkonium and Organosilane ingredients in Formulation B.
Other Forms of Benzlakonium
While preferred formulations according to the invention utilise Benzlakonium chloride, in other embodiments this may be substituted by other forms of Benzlakonium, for example Benzalkonium free base or one or more alternative Benzalkonium salts (e.g. Benzalkonium Bromide, Benzalkonium Saccharinate and Acesulfame Benzalkonium)-.— In each case the weight amounts would be adjusted to provide more or less equivalent function.
Other Organosilanes
Similarly, while preferred forms of the invention utilise 3-(trimethoxysilyl)propyl dimethyl octadecyl ammonium chloride, in other embodiments this may be substituted by other organosilanes, for example one or more of S-(trihydroxysilyl) propyl dimethyl octadecyl ammonium chloride (CAS 199111 -50-7) and n,n-dimethyl-n-[3-(trimethoxysilyl)propyl]-1- tetradecanaminium chloride (CAS 41591 -87-1 )- In each case the weight amounts would be adjusted to provide more or less equivalent function.
Preservatives, Humectants and Surfactants
Further, formulations according to the invention may use alternative preservative, humectant and/or surfactant materials to those of Formulations A, B and C, adjusting the weight amounts as appropriate to provide more less equivalent function. Examples of these are as follows -
