Cosmetics and Personal Care

A cosmetics and personal care laboratory must extract and quantify trace analytes from complex matrices such as emulsions, oils, and aqueous formulations. Contaminants like preservatives, fragrance allergens, and residual solvents can interfere with product safety testing. Microl

Context

The Problem In This Sector

Pain Points

  • Low recovery of polar fragrance compounds due to strong adsorption on unselective sorbents
  • Matrix interference in LC-MS/MS analysis from co-extracted lipids and surfactants
  • Breakthrough of acidic or basic analytes during SPE due to insufficient retention capacity
  • Inconsistent results between batches caused by variability in sorbent performance
  • Method failure when switching between different column chemistries without revalidation

What This Sector Needs

  • Sorbents with high selectivity for polar, non-polar, acidic, basic, and neutral compounds in a single platform
  • Consistent bed packing and particle uniformity to ensure reproducible recovery and cleanup
  • Columns with stable performance across pH 1 to 14 for compatibility with diverse elution protocols
  • Pre-validated sorbent types matching international standards such as GB 29682-2013 and SN/T 2050-2008
  • Multiple column sizes (1, 3, 6, 10 ml) to support method development and high-throughput screening
Where It Is Used

Typical Application Scenarios

  • Extraction of residual antibiotics from cosmetic base formulations prior to LC-MS/MS analysis
  • Cleanup of quaternary ammonium preservatives from aqueous skincare products
  • Isolation of fragrance allergens from emulsified lotions using HLB or MCX sorbents
  • Trace analysis of perfluorinated acids in water-based personal care products
  • Method development for veterinary drug residues in animal-derived ingredients used in cosmetics
Process

How We Work With You

Specify

Select sorbent type based on analyte polarity and charge: HLB for broad-spectrum, MCX for basic compounds, WAX for strong acids, WCX for strong bases

Sample

Trial quantities of 3 ml and 6 ml columns are available for method validation and recovery testing

Standardise

Each column is assigned a unique Cat. No. and includes mass, volume, and package size for exact reorder

Supply

Repeat supply of the same sorbent chemistry and particle size (40 µm) with consistent packing and performance

FAQ

Frequently Asked Questions

Which sorbent should we use for fragrance allergens in emulsions?

Use HLB for non-polar to moderately polar allergens. For polar or ionizable compounds, consider MCX or WAX depending on the analyte charge.

Can we use these columns for LC-MS/MS method validation?

Yes. The HLB, MCX, WAX, and WCX sorbents are validated for use in methods such as GB 29682-2013 and SN/T 2050-2008.

What is the particle size and surface area of the sorbents?

All sorbents have a particle size of 40 µm and a surface area of 600 m²/g.

Do you supply under our own label?

Yes. The OEM division offers OEM contract manufacturing, private-label packing, and custom sorbent configurations.

Are the columns compatible with pH 1 to 14?

Yes. All polymeric sorbents (HLB, MAX, MCX, WAX, WCX) are stable from pH 1 to 14.
