2% Salicylic Acid Serum for Acne: NABL Lab Test Report
NABL lab test report for 2% Salicylic Acid Serum for Acne: heavy metals not detected and pH 5.34. Batch AC5E015.
Safety Summary: 2% Salicylic Acid Serum for Acne
Is 2% Salicylic Acid Serum for Acne 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 AC5E015, met every safety limit the laboratory checked.
Free from lead, cadmium and arsenic. The report found no detectable lead, cadmium or arsenic - each was below the laboratory's detection limit of 0.25 mg/kg.
Free from harmful bacteria and fungi. Total microbial count was Less than 10 cfu/gm (limit 1000 cfu/gm); Total yeast & mould count was Less than 10 cfu/gm (limit 100 cfu/gm).
Gentle, skin-friendly pH. The measured pH is 5.34, which is mildly acidic.
Sulphate-free and paraben-free. The published ingredient list contains no sulphates, parabens, silicones or mineral oil. Preservation uses phenoxyethanol, ethylhexylglycerin and sodium benzoate.
Is it chemical free? No cosmetic is chemical-free - water itself is a chemical. This one is free from sulphates, parabens, silicones, mineral oil and any detectable lead, cadmium or arsenic.
What these results cover. The laboratory findings apply to the tested sample from batch AC5E015 and the parameters listed on this page. Skin tolerance is assessed separately, in the dermatological patch test certificate. NABL accredits laboratories, not products.

A: For the tested batch, microbial counts were reported within the limits of the referenced standard and the specified pathogens were reported Absent. These results indicate the tested sample met the referenced microbiological limits; they do not establish overall product safety.
A: The measured pH in this report is 5.34.
A: The published ingredient list for this product contains no sulphates, parabens, silicones or mineral oil. This is based on the ingredient list, not on the laboratory report, which covers contaminants and microbiological quality.
A: No. The report covers chemical and microbiological parameters on a sample from the stated batch. Performance and cosmetic-benefit claims are made by the brand on the product page and are not part of this laboratory report.
A: It means the substance was below the laboratory's stated detection limit using the specified method, so it was not found at or above that limit in the tested sample.
A: A ULR (Unique Lab Report) number is a one-of-a-kind identifier that NABL-accredited laboratories print on every test report, making it traceable. The ULR for this report is TC1519325000003635F. The original report PDF linked on this page carries the laboratory letterhead and authorised signatory details.
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.
