Parabens Free Testing by HPLC-UV
Parabens testing by HPLC is used to verify paraben-free claims in cosmetic, personal care, and consumer product formulations. Pentyl Labs performs this analysis using high-performance liquid chromatography with ultraviolet detection (HPLC-UV) to screen for parabens and commonly used alternative preservatives at defined limits of quantification.
Parabens have been widely used as preservatives due to their antimicrobial effectiveness. However, many brands now market products as “paraben-free” in response to consumer preference and retailer requirements. Because of this, accurate analytical testing plays a critical role in substantiating these claims.
Pentyl Labs’ parabens testing by HPLC method detects a comprehensive panel of parabens and non-paraben preservatives, including:
Alternative Preservatives
-
Benzoic acid / sodium benzoate (LOQ: 10 ppm)
-
Sorbic acid / potassium sorbate (LOQ: 10 ppm)
-
Dehydroacetic acid / sodium dehydroacetate (LOQ: 10 ppm)
-
Phenoxyethanol (LOQ: 10 ppm)
-
Phenol (LOQ: 10 ppm)
-
Bronopol (LOQ: 50 ppm)
Parabens Panel
-
Methylparabene (LOQ: 5 ppm)
-
Ethylparabene (LOQ: 5 ppm)
-
Propylparabene (LOQ: 5 ppm)
-
Butylparabene (LOQ: 5 ppm)
-
Iso-propylparabene (LOQ: 5 ppm)
-
Iso-butylparabene (LOQ: 5 ppm)
-
Pentylparabene (LOQ: 5 ppm)
-
Phenylparabene (LOQ: 5 ppm)
-
Benzylparabene (LOQ: 5 ppm)
Testing may be performed on raw materials, bulk formulations, or finished products. This flexibility allows manufacturers to verify paraben-free status during development, reformulation, supplier qualification, or prior to market launch.
Parabens testing supports regulatory compliance, retailer requirements, and marketing claim substantiation. The results also help confirm formulation consistency and identify unintended contamination from raw materials or processing equipment.
This service is commonly included within broader Chemical Analysis Services and Preservative Testing Programs. Guidance from regulatory bodies such as the European Commission defines preservative use and labeling expectations for cosmetic products.
Overall, parabens testing by HPLC provides reliable, defensible data that supports paraben-free claims and strengthens consumer confidence.
