2. How the Laboratory Study Was Conducted
2.1 Test Organism and Sample Preparation
The study evaluated Propionibacterium acnes. The report describes subculturing in Modified Brain Heart Infusion Broth under anaerobic conditions at 37°C for five days. The test strain concentration is stated as 5 × 104 CFU/mL.
The three test articles were diluted at a 1:10 ratio in Mueller Hinton Broth. These are laboratory preparation conditions, not instructions to dilute the face wash before use.
2.2 Exposure Times and Controls
The time-kill assessment used exposure intervals of 15, 30, 45, 60, 90, 120 and 180 seconds. Benzoyl peroxide was listed as the positive control, untreated P. acnes culture as the negative control, and fresh Mueller Hinton Broth as the sterility control.
The report describes an in-house standard test procedure, anaerobic incubation and an endpoint OD600 assessment. It presents colony counts, calculated CFU/mL, log values and percentage-reduction entries in its results table.
See sample preparation on page 8 and test procedure on page 9.
3. Comparative Results as Reported
The table below reproduces the percentage-reduction entries for the three test articles from page 11. These figures are presented as reported by the laboratory and have not been independently validated.
| Exposure Time | Sali-Cinamide Face Wash | Neem Powder | Neem Leaf Extract |
|---|---|---|---|
| 15 seconds | 4.39% | 0.84% | 2.58% |
| 30 seconds | 33.18% | 0.84% | 8.25% |
| 45 seconds | 63.68% | 3.48% | 14.78% |
| 60 seconds | 99.58% | 9.28% | 32.58% |
| 90 seconds | NA | 14.78% | 37.36% |
| 120 seconds | NA | 31.81% | 51.19% |
| 180 seconds | NA | 39.38% | 63.68% |
NA: The source table lists NA in the percentage-reduction column for Sali-Cinamide at 90, 120 and 180 seconds, while recording zero colonies at those time points. NA has been retained rather than converted into a 100% claim.
Important Note on the Reported Figures
Page 11 lists 99.58% reduction at 60 seconds for Sali-Cinamide. Page 12 also describes 100% kill at 60 seconds, although the page 11 table records a non-zero colony count at that time point. These statements are not consistent.
The percentage-reduction entries also do not consistently reconcile with the displayed CFU/mL and log-reduction values. The report additionally labels the negative control as untreated culture in the method but records zero colonies for that control in the results table. Laboratory clarification is needed before treating the numerical efficacy or comparative multipliers as verified claims.
This page therefore presents the laboratory's recorded values with their limitations. It does not establish 100% bacterial elimination, a guaranteed acne outcome, or equivalent results on human skin.
Review the complete results table on page 11 and the interpretation on page 12.
4. About the Tested Product
The official product page identifies The Derma Co Sali-Cinamide Anti-Acne Face Wash as a cleanser with 2% Salicylic Acid and 2% Niacinamide. The antimicrobial report names the tested article as Sali-Cinamide Anti-Acne Face Wash.
| Product Information | Official Product Page Details |
|---|---|
| Product format | Rinse-off face wash |
| Highlighted ingredients | 2% Salicylic Acid and 2% Niacinamide |
| Additional listed ingredients | Glycerin, Allantoin, Cica Extract, D-Panthenol and Aquaxyl-related sugar ingredients |
| Full formula and directions | View the official product page |
The antimicrobial report assesses the complete tested sample. It does not isolate the contribution of each ingredient or measure hydration, acne-mark fading, skin-barrier repair or human skin irritation.

6. Frequently Asked Questions
A: It was evaluated for laboratory antimicrobial activity against Propionibacterium acnes, alongside neem powder and neem leaf extract, in the supplied CCFT report.
A: The page 11 table lists 99.58% reduction for Sali-Cinamide at 60 seconds. Page 12 also states 100% kill at that time point, despite a non-zero colony count in the table. Because the reported percentages and counts do not consistently reconcile, these figures need clarification from the laboratory.
A: No. The supplied document describes an in-vitro antimicrobial study. It does not report a trial measuring acne lesions, acne marks or skin irritation in human participants.
A: The study was conducted at the Centre for Cruelty-Free Testing, MIET Meerut, for Honasa Consumer Limited. Nidhi Dixit is listed for Study Director approval on page 3, and Ms. Nidhi Dixit signs the declaration on page 14.
A: The complete PDF is linked in the View the Original Certificate & Full Report section. The signed declaration is on page 14; the results table is on page 11 and the interpretation is on page 12.
A: The report states that Sali-Cinamide Anti-Acne Face Wash, neem powder and neem leaf extract were diluted at a 1:10 ratio in Mueller Hinton Broth. This describes laboratory preparation, not directions for consumer use.
A: No. The 15-to-180-second intervals are laboratory exposure conditions. Follow the product label and official product directions for use; the study does not establish a recommended skin contact time.
A: No. This report evaluates antimicrobial activity and does not report human patch testing or certify the product as non-irritant. Any separate dermatological safety documentation must be assessed on its own evidence.
A: The source report lists NA in the percentage-reduction column for Sali-Cinamide at 90, 120 and 180 seconds. This page retains that notation and does not replace it with a calculated percentage or a 100% claim.
A: No. The report states compliance with OECD Principles of Good Laboratory Practices and no deviations from FDA GLP Regulations during the study. That statement does not constitute FDA product approval.
A: The cover lists Project No. CCFT-2025-06-1424H and Report No. MIET/CCFT/2025-06/1424H. The page headers use CCFT-2025-06-1424H, while the declaration text prints CCFT-2025-06-1424/MIC. These references are reproduced as printed rather than treated as identical.
7. Product Application Guidelines
The official product page provides the following steps. These directions are separate from the laboratory exposure conditions.
