| Finished-product pH | Target range: pH 5.0–6.5 for many rinse-off cleansing products intended for routine skin or hair use. | Liquid shampoo and body wash: typically specify a controlled target and acceptance range, such as pH 5.0–6.5, based on the validated formula. | Request the product specification, test method, calibrated-meter records, and a recent certificate of analysis. pH should be confirmed on the finished product, not only on the raw materials. | Required specification |
| Soap format | Solid soap is generally an alkaline cleansing product because traditional soap is made from fatty-acid salts. | For solid hotel soap, define net weight, dimensions, fragrance level, appearance, hardness, lather, and packaging format rather than applying a liquid-shampoo pH target. | Confirm whether the product is true soap or a synthetic detergent bar. Request finished-product test results and packaging samples. | Format-dependent |
| INCI ingredient label | Ingredients should be listed using recognized International Nomenclature of Cosmetic Ingredients (INCI) names, subject to the destination market’s labeling rules. | Provide a complete ingredient declaration for shampoo, body wash, conditioner, lotion, and soap, including fragrance or allergen information where legally required. | Check the INCI list against the formula, ingredient documentation, allergen requirements, claims, and import regulations of the selling country. | Required label data |
| Ingredient order | Cosmetic ingredients are generally declared in descending order of predominance, subject to applicable local rules and concentration thresholds. | Use the final approved formula and ensure the artwork, carton, sachet, bottle, and refill packaging carry consistent ingredient information. | Compare the approved artwork with the master formula and regulatory review. Confirm that any colorants, preservatives, and fragrance components are correctly identified. | Label control |
| ISO 22716 GMP | ISO 22716 provides guidelines for the production, control, storage, and shipment of cosmetic products under good manufacturing practices. | Prefer a manufacturing site with a current ISO 22716 certificate or equivalent documented cosmetic GMP system relevant to the production facility. | Check certificate scope, issuing body, validity dates, site address, audit status, batch records, sanitation procedures, and change-control documentation. | Good practice |
| Microbiological quality | Water-based shampoos and body washes require microbiological controls. Acceptance limits depend on product type and destination-market requirements. | Define total aerobic microbial count, yeast and mold limits, and absence or control of specified microorganisms according to the applicable standard or customer specification. | Request a recent microbiological certificate of analysis, preservative-challenge or preservation-efficacy evidence where appropriate, and water-quality records. | Batch release check |
| Preservative system | Preservatives must be suitable for the formula and comply with the cosmetic regulations of the destination market. | Specify preservative type, concentration range, compatibility with packaging, and required in-use or stability testing. | Review the formula, regulatory status, stability data, microbial test results, and any restrictions applying to the destination country. | Regulatory check |
| Stability testing | A finished product should remain within defined quality specifications throughout its stated shelf life under labeled storage conditions. | Evaluate appearance, odor, color, pH, viscosity, packaging compatibility, phase separation, and microbial quality under suitable accelerated and real-time conditions. | Request a stability protocol, test results, expiry or period-after-opening rationale, and evidence that the tested packaging matches the wholesale packaging. | Shelf-life support |
| Packaging and dosage | Packaging should protect the formula, prevent leakage, and provide safe and practical dispensing in hotel environments. | Common formats include 20–50 ml bottles, 10–30 ml sachets, 20–40 g solid bars, wall-mounted dispensers, and bulk refill containers, subject to project needs. | Test closure torque, leakage, drop resistance, pump output, label adhesion, batch coding, recyclability information, and compatibility with the formula. | Project-dependent |
| Batch traceability | Each production batch should be identifiable through a batch or lot number linked to manufacturing and quality records. | Use readable batch coding on the primary container and outer carton, with documented retention samples and a defined recall procedure. | Check the batch-number format, production date, expiry or best-before information where required, retention-sample policy, and complaint-handling process. | Quality control |
| Certificate of Analysis | A batch-specific certificate of analysis should demonstrate conformity with the agreed finished-product specifications. | Include appearance, odor, color, pH where applicable, viscosity where applicable, net content, microbiology, and other critical quality attributes. | Confirm that the certificate matches the shipped batch, approved specification, test methods, release date, and authorized quality reviewer. | Recommended per batch |
| Claims and fragrance | Claims such as “moisturizing,” “mild,” “natural,” or “hypoallergenic” should be supportable and compliant with the destination market’s advertising rules. | Define fragrance profile, intensity, allergen disclosure, claim wording, and supporting evidence before approving packaging artwork. | Review claim substantiation, fragrance documentation, safety information, allergen declarations, and consistency between marketing text and formula. | Evidence required |
| Storage and transport | Cosmetic products should be stored and transported in conditions that preserve their quality and packaging integrity. | Define temperature range, humidity protection, pallet configuration, carton strength, transit testing, and protection from direct sunlight or freezing. | Request storage instructions, transport qualification where relevant, carton specifications, and a process for handling damaged or temperature-exposed goods. | Supply-chain control |
