Is cold-process soap (CP soap) suitable for facial cleansing?

Cold-process soap is a gentle body cleanser, but its naturally alkaline pH (typically between 8.5 and 10) temporarily raises the skin's acidic surface pH (approximately 5.5). For dry, reactive, or acne-prone facial skin, formulators often favor soap-free syndets or gentle cleansing emulsions adjusted to physiological pH.

Can I display a "hypoallergenic" claim on my face cream?

The claim "hypoallergenic" is strictly regulated under EU Regulation (EU) No 655/2013. It does not signify zero risk of allergy, but indicates that the formula was deliberately formulated to minimize allergic potential. To substantiate this claim, you must exclude known allergens and conduct clinical sensitization testing (such as the Human Repeat Insult Patch Test: HRIPT) demonstrating the absence of sensitization.

How do you evaluate skin tolerance for a new face cream?

The standard protocol is a clinical patch test under dermatological supervision. The finished formulation is applied under an occlusive patch to the backs of 20 to 30 healthy human volunteers for 24 to 48 hours. A board-certified dermatologist grades cutaneous reactions to confirm the absence of primary irritation, generating a clinical report for the PIF.

Facial Hygiene & Skincare: Formulation & EU Regulation

Facial Hygiene and Skincare: Dermatological Routine Guide and EU Regulatory Compliance

Facial hygiene and skincare represent the historic heart of the cosmetics industry. Cleansing, hydrating, targeting, and protecting form the four pillars of healthy, balanced skin. However, formulating and marketing a complete facial care range (cleansing gels, milks, concentrated serums, emulsions) in Europe involves strict regulatory obligations. Daily application to the delicate facial epidermis requires rigorous safety assessments under Regulation (EC) No 1223/2009. Here is our complete regulatory guide.

The 4 Pillars of a Cohesive Facial Skincare Routine

A scientifically sound facial skincare routine relies on sequential targeted steps that respect skin physiology:

Cleansing (Hygiene): Removing excess sebum, cosmetic residues, and urban pollution. Double cleansing (using a botanical cleansing oil followed by a gentle foaming wash) is widely adopted for its efficacy. The cleanser should be formulated at a slightly acidic physiological pH (around 5.5) to preserve the protective cutaneous acid mantle.
Hydration & Moisture (Care): Supplying water through humectants (glycerin, hyaluronic acid) and locking it in with plant-based emollients. Face creams combine these phases as stable oil-in-water or water-in-oil emulsions.
Targeted Treatment (Serums): Highly concentrated active formulations (vitamin C, niacinamide, retinol) formulated to address specific concerns (wrinkles, hyperpigmentation, barrier repair).
Cutaneous Protection: Daily barrier reinforcement against environmental and oxidative stressors.

Regulatory approval of these formulations requires compiling an exhaustive cosmetic PIF. For foundational criteria governing facial cosmetics, review our guide on the facial skincare PIF.

🔬 Insights from our Cosmetic Safety Assessor

"The SCCS estimates daily facial cream application for an adult at approximately 1.54 grams per day. While this volume is lower than total body lotion exposure, cutaneous penetration is heightened due to the relative thinness of the facial stratum corneum. Selecting mild preservatives and fragrance blends is critical to maintaining a Margin of Safety (MoS) above 100 while eliminating irritation or sensitization risks."

Regulatory Steps to Ensure Compliance for Facial Care Ranges

To market your facial skincare collection legally in France, Switzerland, or the wider European Union, complete the following stages:

Accelerated Stability and Packaging Compatibility Testing: 8 to 12 weeks of thermal stress testing at 40°C to verify that emulsions maintain structural homogeneity without phase separation.
Microbiological Challenge Testing: Compulsory under ISO 11930 for all water-containing formulations (face creams, serums, cleansing gels).
Cosmetic Product Safety Report (CPSR): Comprehensive toxicological review and official sign-off by our qualified Safety Assessor under Article 10(2).
CPNP Registration: Mandatory notification of every finished cosmetic shade on the European Cosmetic Products Notification Portal prior to distribution.

⚠️ 3 Frequent Compliance Pitfalls in Facial Skincare

Exceeding Permissible Active Ingredient Concentrations: For example, salicylic acid is limited to a maximum concentration of 2.0% in leave-on facial products under Annex III of Regulation (EC) No 1223/2009. Over-concentration invalidates the formula.
Omitting Fragrance Allergen Disclosures: If your perfume or essential oil blend contains linalool, limonene, or other regulated allergens above 0.001% in a leave-on face cream, they must appear in the INCI list.
Making Prohibited Medical Acne Claims: Stating that your facial wash or moisturizer "treats cystic acne" or "cures pimples" breaches European cosmetic claims regulations. Stick to authorized cosmetic wording ("purifying", "helps balance blemish-prone skin").
