Mineral Powder Sunscreen for Oily Skin | SPF 50: NABL Lab Test Report
NABL lab test report for Mineral Powder Sunscreen for Oily Skin | SPF 50: heavy metals not detected, pathogens absent and pH 7.38. Batch SCPS0001.
Safety Summary: Mineral Powder Sunscreen for Oily Skin | SPF 50
Is Mineral Powder Sunscreen for Oily Skin | SPF 50 safe? Yes. It was independently tested at Sigma Test & Research Centre, a laboratory accredited by NABL (Accreditation No. TC-5369). The tested sample, from batch SCPS0001, was analysed against the limits in the referenced standards.
Free from lead, cadmium, arsenic, mercury and antimony. The report found no detectable lead, cadmium, arsenic, mercury or antimony - each was below the laboratory's detection limit of 0.25 mg/kg.
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 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 7.38, which is mildly acidic.
Sulphate-free and paraben-free. The published ingredient list contains no sulphates, parabens or mineral oil.
Is it chemical free? No cosmetic is chemical-free - water itself is a chemical. This one is free from sulphates, parabens, mineral oil and any detectable lead, cadmium, arsenic, mercury or antimony.
What these results cover. The laboratory findings apply to the tested sample from batch SCPS0001 and the parameters listed on this page. Skin tolerance is assessed separately, in the dermatological patch test certificate. NABL accredits laboratories, not products.
