Why Test Cosmetics?
Cosmetics and personal care products come into direct contact with the skin, hair, and eyes—making safety and quality non-negotiable.
Hidden contaminants or inaccurate labelling can:
- Cause skin irritation, allergies, or infections
- Lead to regulatory actions (BIS, CDSCO, FDA, EU Cosmetic Regulations)
- Result in costly product recalls and long-term brand damage
- Erode consumer confidence and market credibility

Regular Cosmetics Testing Helps You Ensure:

Regular Cosmetics Testing Helps You Ensure:
- Products are safe, effective, and free from harmful substances
- Compliance with BIS, ISO, FDA, EU, and other global cosmetic standards
- Accurate labelling to meet consumer trust and legal requirements
- Faster and smoother approvals for domestic and export markets
Types of Cosmetic Testing We Provide

Microbial Contamination Testing
Why : Cosmetics can harbor bacteria, yeast, or mold that cause infections.
What we test : Total viable count, E. coli, Pseudomonas, Staphylococcus aureus, Candida, Aspergillus.
Who needs it : Creams, lotions, shampoos, baby care products.

Heavy Metals Testing
Why : Metals like lead, arsenic, and mercury are toxic and restricted globally.
What we test : Lead, cadmium, mercury, arsenic, chromium.
Who needs it : Lipsticks, kajal, powders, hair dyes.

Preservative Efficacy (Challenge Test)
Why : Preservatives must control microbial growth during shelf life.
What we test : Preservative system’s ability to inhibit microbial growth over time.
Who needs it : All formulations with water content (lotions, creams, gels).

Stability & Shelf Life Testing
Why : Products must remain safe and effective over their storage period.
What we test : Physical, chemical, and microbial stability under different conditions.
Who needs it : Every cosmetic brand before product launch.

Safety & Toxicology Testing
Why : To assess irritation, sensitization, or toxicity risks.
What we test : Patch tests, in-vitro toxicity, dermatological assessments.
Who needs it : New formulations, baby products, sensitive skin products.

Label Claim Validation
Why : To back marketing claims with data (e.g., “paraben free,” “dermatologically tested”).
What we test : Ingredient verification, efficacy studies, compliance with BIS/Cosmetic Rules.

FAQs
How much sample is required for cosmetic testing?
Sample quantity varies by test:
- Microbiology: 50–100 g/ml
- Stability: 10–15 containers
- Challenge test: 6–12 units
- Heavy metals: 20–50 g/ml
We will tell you the exact quantity based on the test plan.
How should cosmetic samples be packed for testing?
Samples should be:
- Sealed in original packaging
- Labelled with batch number, MFG/EXP date
- Protected from heat and light during transport
Do you provide sample pickup?
Yes. Sample pickup is available, especially for bulk and urgent submissions.
Do cosmetics in India need BIS or CDSCO approval?
Yes. Depending on the product:
- Certain cosmetics (like hair dyes, skin creams) require BIS compliance.
- Imported cosmetics require CDSCO registration.

Yes. Reports follow ISO, BIS, FDA, EU Cosmetic Regulation (EC 1223/2009) standards, making them suitable for export markets.
Do cosmetics need additional testing for EU or US markets?
Yes. Export markets may require:
- Safety Assessment (CPSR)
- Stability & compatibility testing
- Preservative efficacy
- Heavy metals & allergens screening
- Label compliance check
Can international clients send samples for testing?
Yes. We accept samples from overseas brands with guidance on customs, shipping, and compliance.
Do you support cosmetic product development or reformulation?
Yes. We work with brands, formulators, and startups to refine formulations, choose preservatives, and improve stability.
Can you help test prototype or small-batch products?
Yes. We support startups and private labels with prototype testing, safety screening, and early-stage stability studies.
