Cosmetics & Personal Care Solutions
Laboratory Testing, Product Development & Scientific Support for Cosmetics & Personal Care Companies
Cosmetics and personal-care products combine ingredients, formulations, microorganisms,
preservatives, packaging, stability, biological interaction, manufacturing, and product
quality.
Scientific questions can arise throughout development and manufacturing
.
A cosmetics or personal-care company may need to understand:
Why did a formulation change unexpectedly?
Is microbial contamination affecting the product?
What analytical method is appropriate?
Is the preservative system performing as intended?
How should a new formulation or ingredient be characterized?
Could raw materials or suppliers be contributing to product inconsistency?
How does the product interact with biological systems?
CMDC Labs supports appropriate cosmetics and personal-care projects with multidisciplinary
resources spanning microbiology, preservative-related testing, cell-based testing,
biological-response studies, product characterization, raw-material evaluation, stability-
related investigation, contamination troubleshooting, product development, analytical
testing, scientific consulting, and quality support.

↓
Characterize the Contaminant
↓
Review Product & Manufacturing History
↓
Evaluate Product / Raw Materials / Water / Environment
↓
Compare Potential Sources
↓
Targeted Follow-Up Testing
The purpose is not simply to confirm that contamination exists, but to generate evidence that
can help narrow potential sources.
Raw Material & Ingredient Testing
Understand What Goes Into the Product
Ingredient and raw-material variability can influence finished-product quality, formulation
performance, microbiology, and stability.
Scientific evaluation may involve:
- Material characteristics
- Chemical composition
- Microbiological quality
- Contamination
- Heavy metals where appropriate
- Supplier differences
- Lot-to-lot variation
- Comparative performance
Testing incoming materials can become particularly useful when a product changes after a new
supplier or raw-material lot is introduced.
Supplier & Ingredient Change Investigation
A supplier change can introduce differences that may not be obvious from documentation alone.
A useful comparison may include:
Previous Ingredient
vs.
New Ingredient and Acceptable Product
vs.
Problematic Product
Analytical and microbiological testing can then focus on measurable differences that may be
relevant to the observed change.
Product Development for Cosmetics & Personal Care
Generate Scientific Information During Formulation
Developing or reformulating a product can introduce questions involving:
- Ingredients
- Preservatives
- Formulation
- Microbiology
- Product characteristics

CMDC Labs can evaluate appropriate development projects requiring analytical,
microbiological, biological, or multidisciplinary laboratory support.
Scientific work during development can help teams better understand the product before routine
manufacturing and quality testing are established.
Product Characterization
Product characterization can help establish measurable information about a cosmetic or
personal-care product during development, comparison, manufacturing, or troubleshooting.
Depending on the scientific objective, characterization may involve:
- Chemical characteristics
- Ingredients
- Microbiological characteristics
- Comparative formulations
- Raw-material differences
- Product consistency

- Water
- Temperature
- Light
- Moisture
- Packaging
- Microorganisms
- Product chemistry
Stability-related studies can help evaluate measurable changes under defined conditions.
When a product changes unexpectedly, scientific investigation may be needed to determine:
What changed?
and
Which variables may be contributing?
Product Consistency & Batch Investigation
Unexpected differences between production lots may result from:
- Raw-material variation
- Supplier changes
- Ingredient differences
- Formulation
- Manufacturing conditions
- Microorganisms
- Packaging
- Storage
- Process changes
Comparative laboratory testing can help determine whether measurable differences exist
between acceptable and problematic lots.
Those findings can then guide more targeted investigation.
Cell-Based Testing
Evaluate Biological Responses in Appropriate
Experimental Models
Some cosmetics and personal-care projects may require biological information beyond chemical
or microbiological testing.
Where appropriate, cell-based testing can help investigate how a product, ingredient, material,
or formulation interacts with biological systems.
Projects may involve:
- Comparative biological response
- Product or ingredient evaluation
- Cell-based assays
- Cytocompatibility-related questions
- Research

interactions involving products, ingredients, or experimental formulations.
Potential applications may include:
- Comparative testing
- Product-development studies
- Biological-response investigation
- Research
Project design should reflect the scientific objective and intended use of the results.
Cosmetics & Personal Care Troubleshooting
Some problems begin with an observation rather than a defined testing requirement:
“The formulation changed.”
“Microbial contamination appeared unexpectedly.”
“Shelf life decreased.”
“One batch behaves differently.”
“The problem began after changing an ingredient or supplier.”
“We don’t know whether the issue is microbiological, chemical, or formulation-related.”
These situations may require several scientific perspectives rather than a single routine test.
Manufacturing Troubleshooting
A finished product may change even when the intended formula remains the same.
Potential contributors may include:
- Raw materials
- Ingredients
- Water
- Suppliers
- Process conditions
- Equipment
- Environmental contamination
- Microorganisms
- Packaging
- Storage
CMDC Labs can evaluate multidisciplinary investigations where several potential variables need
to be differentiated experimentally.
