Is container compatibility testing required for face scrubs in jars?

Yes. Facial scrubs are frequently packaged in wide-mouth plastic jars (PP, PET, or glass). During accelerated stability testing (8 to 12 weeks at 40°C), the laboratory confirms that the formula does not interact with the plastic wall or cap liner and that container seals prevent water evaporation or product drying.

Can an anhydrous scrub based on apricot seed powder bypass challenge testing?

Yes. If an exfoliating scrub is formulated without water (such as ground apricot seed powder suspended solely in botanical oils and butters), it presents low microbiological susceptibility under ISO 29621 and is exempt from challenge testing. However, if water is incorporated into the formulation, challenge testing under ISO 11930 is legally required.

How do you substantiate a "refines skin texture" claim for a face scrub?

The claim "refines skin texture" is a cosmetic, non-medicinal claim. It is substantiated through a documented consumer in-use study or sensory evaluation protocol on volunteer panels during formula development, recorded in Part B of the PIF.

Face Scrub PIF: Regulatory Compliance and Safety Validation for Facial Exfoliants

Facial scrubs and chemical exfoliants are essential skincare steps designed to slough off dead stratum corneum cells, refine epidermal texture, and restore facial radiance. Whether formulated with physical abrasives (mechanical scrubs) or fruit acids (AHA/BHA chemical exfoliants), these products act directly on delicate facial tissue. Marketing them across the European Union requires compiling an exhaustive Product Information File (PIF) compliant with Regulation (EC) No 1223/2009. Here is our expert compliance guide.

Formulation Constraints for Facial Exfoliants and Scrubs

Facial exfoliating cosmetics utilize mechanical or chemical peeling agents that receive targeted toxicological evaluation by our Cosmetic Safety Assessor during the Cosmetic Product Safety Report (CPSR):

Physical Exfoliating Particles: Hydrogenated jojoba wax beads (INCI: Hydrogenated Jojoba Oil), micronized bamboo silica, or finely ground fruit seed powders. The Safety Assessor confirms particle morphology to ensure smooth spherical edges that will not cause micro-tears in the epidermal barrier. The use of synthetic plastic microbeads (polyethylene) is strictly prohibited in the EU under Commission Regulation (EU) 2023/2055.
Chemical Exfoliants (AHAs and BHAs): Glycolic acid (INCI: Glycolic Acid), lactic acid, or salicylic acid. Salicylic acid is strictly capped at a maximum of 2.0% in facial cosmetics under Annex III of Regulation (EC) No 1223/2009. Finished product pH must be rigorously controlled (typically pH >= 3.5) to avoid severe cutaneous or ocular irritation hazards.
Carrier Emollient Lipids: Sweet almond oil (INCI: Prunus Amygdalus Dulcis Oil), apricot kernel oil, or jojoba wax to cushion the skin barrier against mechanical friction.

The facial scrub PIF compiles this formulation, analytical purity, and safety data. For baseline requirements on facial formulations, consult our guide on the facial skincare PIF and our central overview on the cosmetic PIF.

🔬 Insights from our Cosmetic Safety Assessor

"Aqueous facial scrubs must undergo a 28-day preservative efficacy challenge test in accordance with ISO 11930. Because these products are stored in warm, humid bathrooms and frequently sampled with wet fingers from jars or wide-mouth tubes, the risk of opportunistic bacterial contamination is acute. The preservative system must be robust, dermatologically gentle, and validated through certified laboratory testing."

Structure of the Product Information File (PIF) for Facial Scrubs

To validate your facial scrub for legal distribution in France, Switzerland, or the wider European Union, the compliance dossier held at your registered address must include:

Complete qualitative and quantitative formulation data.
The Cosmetic Product Safety Report (CPSR - Part A and Part B) signed by our qualified Safety Assessor under Article 10(2).
Official declaration certifying facility compliance with Good Manufacturing Practices (Cosmetic GMP / ISO 22716).
Accelerated stability and packaging compatibility test reports, alongside microbiological challenge testing.
Official CPNP electronic notification receipt.

⚠️ 3 Frequent Compliance Pitfalls in Facial Scrubs

Incorporating Banned Plastic Microbeads: Solid non-biodegradable synthetic polymer beads are prohibited across the EU. Formulate exclusively with natural abrasives (jojoba beads, silica, cellulose).
Thermal Instability of Suspended Particles: If exfoliating beads settle irreversibly or float to the surface during accelerated stability testing at 40°C, the formulation is considered physically unstable and cannot be approved.
Making Prohibited Medical Claims on Acne: Claiming that a facial scrub "cures cystic acne" or "eradicates acne scars" breaches cosmetic claims regulations. Restrict wording to cosmetic functions ("gently purifies", "unclogs pores", "smooths skin surface").
