Quality Control of Cosmetic Products

Cosmetic quality evaluates all materials and final products in accordance to ISO 22716 and the Modernization of Cosmetics Regulation Act of 2022 (MoCRA); the product safety substantiation requirements, require effective QA/QC and toxicological risk assessment based analytical testing, microbiological activity to identify potential product defects and safety concerns before products reach consumers.

DJC provides support for pre-testing new products and preliminary toxicological reviews, including the review of third-party testing results and gap analysis.

Regulatory Requirements

1. Raw Materials and Packaging Materials

Raw materials and packaging materials are identified, sampled, examined or tested against acceptance specifications. Materials failing acceptance criteria are identified and controlled to prevent their use in manufacturing.

References: ISO 22716:2007, Clause 6; FDA Cosmetic GMP Guidelines/Inspection Checklist, Section 4.

2. In-Process Quality Control

Testing during production evaluates intermediate product characteristics, mixing and processing, contamination, and conformance with process specifications. Measurements are recorded to determine acceptance or rejection at individual manufacturing stages.

References: ISO 22716:2007, Clause 7.2; FDA Cosmetic GMP Guidelines/Inspection Checklist, Section 5.3.

3. Laboratory Testing and Analytical Control

Raw materials, in-process samples, and finished products are examined for identity, physical and chemical properties, microbiological contamination, unwanted chemical contaminants, and compliance with established specifications. Testing methods and analytical results provide documented evidence for acceptance or rejection.

References: ISO 22716:2007, Clause 9; FDA Cosmetic GMP Guidelines/Inspection Checklist for Cosmetics, Section 6 — Laboratory Controls.

4. Microbiological Quality and Preservation

Microbiological testing evaluates contamination in raw materials, manufacturing water, intermediates, and finished products. Preservative effectiveness testing evaluates the adequacy of preservation under relevant storage and foreseeable consumer-use conditions.

References: ISO 22716:2007, Clause 9; FDA Cosmetic GMP Guidelines/Inspection Checklist, Sections 6.1, 6.3, and 6.4.

5. Finished-Product Testing and Release

Finished products are evaluated against established specifications before release. Test results, product identification, and control status are documented to establish whether the product meets acceptance criteria.

References: ISO 22716:2007, Clauses 8, 9; FDA Cosmetic GMP Guidelines/Inspection Checklist, Sections 6.1, 7.3.

6. Out-of-Specification Results and Product Rejection

Materials and products failing specifications are identified, investigated, and controlled to prevent unintended use or release. Deviations and corrective actions are documented and evaluated before disposition.

References: ISO 22716:2007, Clauses 10, 13; FDA Cosmetic GMP Guidelines/Inspection Checklist, Sections 4.5, 7.

7. Documentation and Quality Control Records

Manufacturing and laboratory records document raw-material identification, batch processing, sampling, testing, analytical results, and acceptance or rejection decisions. These records provide traceability of materials and finished products.

References: ISO 22716:2007, Clause 17; FDA Cosmetic GMP Guidelines/Inspection Checklist, Section 7.

8. MoCRA Requirements for Cosmetic Quality

FD&C Act §606 — 21 U.S.C. §364b, Good Manufacturing Practice: Directs FDA to establish cosmetic GMP regulations intended to protect public health and prevent adulteration. This statutory provision does not prescribe individual laboratory QC test methods itself.

FD&C Act §608 — 21 U.S.C. §364d, Safety Substantiation: Requires the responsible person to ensure and maintain records supporting adequate substantiation of cosmetic product safety. Quality Control testing, including chemical analysis, microbiological evaluation, stability testing, and preservative effectiveness testing, may contribute supporting evidence when relevant to the product's safety assessment.

QA / QC Related Cosmetic Product Recalls

Deficiencies in Quality Assurance (QA) and Quality Control (QC) can allow product defects, contamination, formulation inconsistencies, and packaging failures to go undetected during manufacturing and product release. Adverse events, consumer complaints, and product recalls may reveal gaps in existing testing procedures, acceptance criteria, or manufacturing controls. Strengthening QA/QC through expanded analytical testing, improved process monitoring, and retailer-specific compliance gap analysis can help identify potential product failures before distribution and reduce the risk of FDA recalls.

Based on FDA enforcement data analyzing cosmetic product recalls from 2011 to 2023, the causes of cosmetic recalls are heavily skewed toward a single major point of failure: microbiological contamination.

The FDA classifies recalls into three risk categories:

· Class I (Serious Risk): Dangerous products that could cause serious health problems or death.

· Class II (Moderate Risk): Products that might cause a temporary or medically reversible health issue.

· Class III (Low Risk): Products that violate FDA labeling or manufacturing laws but are unlikely to cause adverse health reactions.

Here is the breakdown of the most common causes for cosmetic product recalls:

1. Microbial Contamination (~77% of all recalls): This is by far the leading cause, responsible for 80% of all Class I (highest risk) recalls. The most common pathogens detected are Pseudomonas and Burkholderia species. These bacteria can cause severe infections, particularly when the cosmetic is used near the eyes, mucous membranes, or on damaged skin. This usually stems from inadequate preservative systems, poor water quality control during manufacturing, or unsanitary equipment.

2. Inorganic Contamination (~10%): This involves the unintended introduction of physical or chemical hazards into the product during manufacturing or from raw materials. The most common offenders in this category are heavy metals (like lead) and asbestos (often found as a contaminant in talc-based products).

3. Fungal Contamination (~8%): While less common than bacterial contamination, fungi such as Candida species and Aspergillus are frequently found in contaminated formulations, particularly those with high water content.

4. Undeclared or Incorrect Ingredients (~7%): This occurs when a product contains an active ingredient, allergen, or color additive that is not listed on the label, or when a banned or restricted ingredient is used.

5. Labeling and Packaging Errors (~5%): Missing expiration dates, incorrect net weight declarations, or packaging defects that compromise the product.

Product recalls can expose deficiencies in quality that may not be identified through routine manufacturing inspections and testing. For cosmetic manufacturers of all sizes, independent technical evaluations can identify gaps in existing practices, assess the effectiveness of corrective and preventive actions (CAPA), and determine whether potential causes of product failures have been adequately addressed. Desert Juice Company (DJC) provides independent QA/QC gap analysis, technical review of manufacturing practices, third-party testing evaluations, and CAPA assessments to help manufacturers identify overlooked deficiencies, strengthen product quality, and reduce the risk of initial or recurring product recalls.
