Sensitive Skin Solutions Body Wash

Root Cause

Inadequate sealing (no induction seal), incorrect cap torque, weak bottle material, pump not secured for shipping.

What to Specify / Ask Supplier

Require induction seals on all bottles. Specify dispenser type (e.g., locking pump) and require pumps to be taped down for shipping. Request transit testing.

QC Check (What "Good" Looks Like)

Invert a sealed bottle and apply pressure. Perform a drop test on a sample shipping carton to simulate transit stress.

Root Cause

Incorrect pH, undeclared allergens/fragrances, raw material contamination, formula not matching 'tear-free' or 'hypoallergenic' claims.

What to Specify / Ask Supplier

Require a specific pH range (e.g., 5.0-6.0). Demand third-party testing reports for 'Dermatologist Tested', 'Hypoallergenic', and 'Tear-Free' claims. Request a Certificate of Analysis (COA) for each batch.

QC Check (What "Good" Looks Like)

Use pH strips to test a sample from each batch. Conduct a user panel test with pre-production samples. Cross-reference the INCI list with the approved formula.

Root Cause

Poor process control during mixing (temperature, time), variation in raw material quality, lack of master standard.

What to Specify / Ask Supplier

Provide an approved physical 'master' sample. Specify acceptable viscosity range (in cPs) and color/scent parameters (e.g., Pantone for color).

QC Check (What "Good" Looks Like)

Visually compare production sample against the master sample for color and clarity. Check viscosity with a viscometer. Perform a sensory check for scent consistency.

Root Cause

Ineffective preservative system, contaminated water source, unhygienic production environment (non-GMP compliant).

What to Specify / Ask Supplier

Require supplier to have GMP (Good Manufacturing Practices) certification. Request micro-challenge test results (PET) for the formula and microbial testing reports for each production batch.

QC Check (What "Good" Looks Like)

Review the Certificate of Analysis (COA) for each batch to ensure it passes microbial limits (e.g., Total Viable Count, Yeast & Mold).

Root Cause

Poor emulsion stability, incorrect ingredient mixing order, temperature fluctuations during shipping/storage.

What to Specify / Ask Supplier

Require formula stability testing data (e.g., 3 months at 40°C). Specify shipping and storage temperature requirements.

QC Check (What "Good" Looks Like)

Keep a production sample at room temperature and in a warmer spot (e.g., sunny window) for 2 weeks. Check for any separation or changes in texture.

Root Cause

Low-quality pump mechanism, cracked bottle due to thin walls, incorrect bottle/cap threading.

What to Specify / Ask Supplier

Specify pump output volume (e.g., 2cc per pump) and require a minimum number of actuations without failure (e.g., 500). Specify bottle wall thickness.

QC Check (What "Good" Looks Like)

Test the pump on 10-20 sample units to check for smooth action, consistent output, and no clogging. Squeeze bottles to check for weakness.

Root Cause

Use of old raw materials, production long before shipping, poor inventory management by the supplier.

What to Specify / Ask Supplier

Specify a minimum remaining shelf life upon delivery (e.g., 'at least 24 months'). Require the manufacturing date and expiration date to be clearly printed on each unit.

QC Check (What "Good" Looks Like)

During inspection, check the printed expiration dates on a sample of units and the outer cartons to ensure they meet the specified requirement.
