NABL lab test report for Collagen & Vitamin C Overnight Moisture Wrapping Mask
Collagen & Vitamin C Overnight Moisture Wrapping Mask: NABL Lab Test Report
NABL lab test report for Collagen & Vitamin C Overnight Moisture Wrapping Mask: pathogens absent, microbial counts within limits, pH 5.54. Initial reading of an accelerated shelf-life study. Batch CM6E001.
Safety Summary: Collagen & Vitamin C Overnight Moisture Wrapping Mask
Is Collagen & Vitamin C Overnight Moisture Wrapping Mask safe? Yes. It was independently tested at Sigma Test & Research Centre, a laboratory accredited by NABL (Accreditation No. TC-15193). The tested sample, from batch CM6E001, was analysed against the limits in the referenced standards.
Free from harmful bacteria and fungi. Four organisms were tested: Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. All were reported Absent. Total microbial count was Less than 10 cfu/gm (limit NMT 1000 cfu/gm); Total yeast & mould count was Less than 10 cfu/gm (limit NMT 100 cfu/gm).
Skin-compatible pH. The sample recorded a pH of 5.54, within the mildly acidic range of healthy skin - relevant for a mask designed to sit on the face for 6 to 8 hours overnight.
Sulphate-free and paraben-free. The brand states on the product page that the formula is sulphate- and paraben-free. This is a brand statement, not a laboratory finding.
What this report is. These are the Initial readings of an accelerated shelf-life study (40°C ± 2, 65% RH ± 5). The laboratory recorded the product's baseline microbiology, pH, viscosity and density before the ageing cycles begin. Heavy metals were not part of this test panel.
What these results cover. The laboratory findings apply to the tested sample from batch CM6E001 and the parameters listed on this page. Skin tolerance is assessed separately, in the dermatological patch test certificate. NABL accredits laboratories, not products.

Understanding These Tests for Collagen & Vitamin C Overnight Moisture Wrapping Mask
Physical & Organoleptic
On the tested sample, Collagen & Vitamin C Overnight Moisture Wrapping Mask was recorded as an off white viscous liquid, off white in colour and with a characteristic odour.
These checks record what the laboratory observed in the sample as received, and form the baseline against which later ageing cycles will be compared.
Physico-Chemical Parameters
Collagen & Vitamin C Overnight Moisture Wrapping Mask recorded pH 5.54, viscosity 5615 cps and density 1.040 g/ml. The standard sets no numeric specification for these; they are reported as measured.
pH 5.54 sits in the mildly acidic range of healthy skin, which matters for a product worn on the face for a full night. Viscosity of 5615 cps describes a thick, spreadable liquid - consistent with a mask that is applied, dries to a film in 15 to 20 minutes, and peels off in the morning.
Accelerated Shelf-Life Study
The report is marked Accelerated Shelf Life Study, Initial, Temp: 40°C ± 2, Humidity 65% RH ± 5. In this design, the product is held at elevated temperature and humidity to simulate ageing, and the same parameters are re-measured after set cycles. The values on this page are the starting point.
An accelerated study cannot by itself set the shelf life; it is the comparison between this baseline and the later cycles that does. Only the Initial reading has been published here.
Microbial Counts
Collagen & Vitamin C Overnight Moisture Wrapping Mask recorded total microbial count Less than 10 cfu/gm against a limit of NMT 1000 cfu/gm and total yeast & mould count Less than 10 cfu/gm against a limit of NMT 100 cfu/gm.
These tests count viable microorganisms against the limits set by the standard.
Pathogens
In the tested sample of Collagen & Vitamin C Overnight Moisture Wrapping Mask, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans were reported Absent - not detected in the tested quantity.
Pathogen tests cover only the organisms listed, not all microorganisms.

What This Report Shows
What the results demonstrate
- Physical characteristics, pH, viscosity and density of the tested sample were recorded as the baseline of an accelerated shelf-life study.
- The tested sample met the microbiological count limits of the referenced standard.
- The four specified pathogenic microorganisms were reported Absent in the tested sample.
- Testing was performed by an NABL-accredited laboratory.
What the results do not demonstrate
- They do not certify the product; NABL accredits laboratories, not products.
- They do not include heavy-metal testing - lead, cadmium, arsenic, mercury and antimony were not part of this test panel.
- They do not establish shelf life on their own; only the Initial reading is published, not the later ageing cycles.
- They do not establish overall safety or suitability for every individual; skin tolerance is covered by the separate patch test certificate.
- They do not prove any cosmetic-benefit or performance claim; those are made on the product page.
- They apply to the tested sample from the stated batch, not necessarily to other batches.

View ProductFrequently Asked Questions
A: For the tested batch, microbial counts were reported within the limits of the referenced standard and Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans were reported Absent. These results indicate the tested sample met the referenced microbiological limits; they do not establish overall product safety.
A: Not in this report. This report is the Initial reading of an accelerated shelf-life study and covers microbiology, pH, viscosity and density. Lead, cadmium, arsenic, mercury and antimony were not part of this test panel.
A: The product is held at 40°C ± 2 and 65% RH ± 5 to simulate ageing, and the same parameters are re-measured after set cycles. "Initial" is the baseline reading before ageing begins. The values on this page are that baseline.
A: The sample recorded pH 5.54, which sits in the mildly acidic range of healthy skin. For a mask worn 6 to 8 hours, a pH in this range is the appropriate design target. Skin tolerance itself is assessed in the separate patch test certificate.
A: The brand states on the product page that the formula is sulphate- and paraben-free. This is a brand statement based on the formulation, not a laboratory finding - the report covers microbiological quality and physico-chemical parameters.
A: No. The report covers microbiological and physico-chemical parameters on a sample from the stated batch. Performance claims such as firming, brightening or hydration are made by the brand on the product page and are not part of this laboratory report.
A: "Absent" means a specified microorganism was not detected in the tested quantity using the referenced method. "Less than 10 cfu/gm" means fewer than 10 colony-forming units per gram were counted, which is the lower reporting threshold of the method.
A: No. NABL accredits laboratories, not products. This page reports the results of testing performed at Sigma Test & Research Centre, an NABL-accredited laboratory (Accreditation No. TC-15193) on a sample of this product. It does not represent a product certification by NABL.
A: The report covers batch CM6E001 (manufactured 05/2026, use before 24 months). The laboratory report states the tested sample as 50 ml x 5 in each cycle. Results refer only to the tested sample and the parameters listed.
