Grant Lloyd provides comprehensive personal care Quality Control and Testing Services. Specifically, our onsite inspections safeguard product safety and confirm exact compliance at every stage of manufacturing.

In addition, we protect your brand’s reputation through accredited Laboratory Testing, Vendor Evaluation, and Regulatory Compliance Consultancy solutions.

Our end-to-end quality services cover Raw Material Screening, Microbiological Testing, Packaging Seal Integrity, and Vendor Audits. Consequently, we help you satisfy standards including EU Cosmetics Regulation (EC 1223/2009), US FDA MoCRA, REACH, and ISO 22716 Good Manufacturing Practices (GMP). As a result, you secure smooth global distribution and complete retail confidence.

Personal Care Quality Control & Product Testing Services

Beauty and personal care formulations require strict Quality Control to guarantee skin compatibility and formula stability. For this reason, Grant Lloyd delivers expert Quality Control Inspections, Vendor Audits, and accredited Laboratory Testing for skincare, hair care, and cosmetics. First, we identify formulation inconsistencies and packaging leaks early in manufacturing. Consequently, you deliver safe and compliant products to global markets with complete confidence.

Microbiological & Preservative Testing

Formulations containing water or botanical extracts are highly susceptible to microbial growth. Consequently, contamination can cause spoilage, bad odours, and skin infections. We perform comprehensive Laboratory Screening and Preservative Efficacy Testing early in production. As a result, we verify shelf-life stability and ensure your products remain safe for daily use.

  • Preservative Efficacy Testing (Challenge Testing): Evaluating formulation resilience against intentional microbial inoculation (ISO 11930 / USP <51>) to verify preservative system strength over time.
  • Total Viable Count (TVC) Screening: Quantifying aerobic mesophilic bacteria, yeast, and mould counts (ISO 21149 / ISO 16212) to ensure raw materials and finished batches meet strict hygiene thresholds.
  • Pathogen-Free Verification: Testing for specified high-risk microorganisms, including Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans (ISO 18415 / ISO 22718).
  • Raw Material & Water Quality Audits: Screening purified water systems, botanical extracts, and bulk ingredients for microbial loads prior to batch production.
  • Packaging Antimicrobial Integrity: Assessing container seals and dispensing mechanisms (such as airless pumps) to prevent secondary microbial contamination during consumer usage.

Chemical & Heavy Metal Safety

Formulations applied directly to the skin or hair can absorb toxic substances if raw materials are unverified. Therefore, we perform accredited Laboratory Testing to identify chemical impurities, heavy metal traces, and banned ingredients. Specifically, this screening protects consumer health and prevents regulatory barriers.

  • Heavy Metal Trace Analysis: Quantitative testing for toxic heavy metals (lead, arsenic, mercury, cadmium, antimony, nickel) via ICP-MS/AAS to ensure compliance with FDA and EU safety limits.
  • Restricted & Banned Substances Screening: Laboratory analysis to detect prohibited chemicals, including phthalates, parabens, formaldehyde releasers, dioxane, and 1,4-dioxane.
  • MoCRA & EU Cosmetics Regulation (EC 1223/2009): Comprehensive chemical audits verifying ingredient safety, concentration limits, and mandatory labelling requirements for US and European entry.
  • REACH & SVHC Compliance: Screening raw ingredients, packaging components, and synthetic compounds for Substances of Very High Concern (SVHC).
  • California Proposition 65 & Allergen Testing: Identifying reportable chemical warnings and screening fragrance allergens (26/56 EU fragrance allergens) to ensure clear packaging disclosures.

Stability & Compatibility Audits

Personal care formulations must maintain their texture, scent, and active performance throughout their shelf life. For instance, we perform accelerated Stability Trials and Package Compatibility Testing under varying temperature conditions. As a result, your formulations remain effective, stable, and visually appealing throughout distribution.

  • Accelerated Real-Time & Thermal Stability: Incubating formulations under controlled temperature and humidity conditions (40’c / 75% RH) to evaluate long-term shelf-life (6, 12, 24 or 36 months).
  • Package Interaction & Compatibility Audits: Testing for plasticiser migration, container stress cracking, product discolouration, or corrosion caused by formula interactions with primary packaging.
  • Organoleptic & Physical Property Evaluation: Monitoring changes in colour, texture, fragrance profile, phase separation, and viscosity over time.
  • pH Balance & Active Degradation Monitoring: Tracking pH fluctuations and key active ingredient concentration levels across testing intervals to guarantee product efficacy.
  • Freeze-Thaw Cycle Testing: Subjecting liquid, cream, and lotion formulations to extreme temperature fluctuations to prevent emulsion breakdown during transit.

Packaging Leak & Functionality Checks

Faulty dispensing mechanisms and packaging leaks can damage secondary cartons and ruin customer experience. Therefore, we conduct rigorous Mechanical Testing and Vacuum Leakage Audits on primary packaging. In addition, we verify that pumps, droppers, airless bottles, and tubes perform flawlessly during daily use.

  • Vacuum Chamber Leakage Testing: Testing filled containers under simulated atmospheric pressure drops to identify micro-gaps, thread defects, or cap seal failures.
  • Dispenser Functionality & Prime Rate Audits: Verifying pump stroke counts to first discharge, dose uniformity per actuation, and smooth spring-back action on lotions, sprays, and airless dispensers.
  • Torque & Closure Verification: Measuring application and removal torque on screw caps and flip-top lids to prevent leaking while ensuring ease of opening for consumers.
  • Tube Seal Integrity & Burst Testing: Evaluating heat-sealed crimps on flexible plastic and laminate tubes for pressure resistance and leak prevention.
  • Drop & Inverted Leakage Audits: Subjecting assembled units to drop impact tests and prolonged inverted storage to verify cap lock-outs and travel-safe durability.

GMP & Vendor Auditing

Brand reputation in the personal care industry depends heavily on strict hygiene and ethical manufacturing standards. First, our Vendor Audits evaluate vendor compliance against ISO 22716 Good Manufacturing Practices (GMP). Furthermore, we verify operational hygiene and local environmental regulations to safeguard your supply chain.

  • ISO 22716 Cosmetics GMP Compliance: Auditing cleanroom hygiene, equipment calibration, batch documentation, and cross-contamination prevention protocols.
  • Environmental & Waste Management: Evaluating hazardous chemical storage, wastewater discharge treatment, noise control, and local environmental permit compliance.
  • Social & Ethical Workplace Standards: Assessing workplace safety, fair labour practices, emergency preparedness, and worker health protections.
  • Raw Material & Inventory Controls: Verifying raw ingredient storage conditions, temperature / humidity controls, and lot traceability from arrival to finished goods.
  • Corrective Action Plan (CAP) Tracking: Partnering with vendor management post-audit to implement and monitor root-cause solutions for any identified non-conformities.
