pH value: Verify according to the category standard range to avoid deviating from the skin tolerance range or affecting the stability of the formula
Viscosity: For creams, gels, and cleansing products, the viscosity range needs to be confirmed to avoid significant variations between batches
Microbiological indicators: Verify the total bacterial count and specific bacterial indicators according to the compliance requirements of the target market, ensuring they meet the local access standards
Heavy metals and restricted substances: Verify the presence of prohibited and restricted ingredients in accordance with the regulations of the target market to avoid customs clearance risks
The core risks of oil and fat products are oxidative rancidity and turbidity at low temperatures, which should be emphasized during procurement:
Stability assessment: Whether there is a rancid odor or color deepening under high-temperature accelerated testing; whether there is solidification or stratification under low-temperature testing, and whether it can be restored after returning to room temperature
Raw material specifications: Confirm the concentration %w/w of base oil and active ingredients, fatty acid composition, and check the addition of antioxidant system
Packaging material compatibility: Confirm the light-proof property of the bottle and the sealing integrity of the dropper/pump head to prevent oxygen from entering and accelerating oxidation
Representative products for reference: GHK-Cu blue copper peptide essence oil, kojic acid and niacinamide spot-fading essence oil, camellia brightening and repairing essential oil, and other OEM customized products, which require additional verification of the solubility and system homogeneity of the active ingredients
The core risks of freeze-dried powder are excessive moisture content and loss of activity. The key points of quality inspection include:
Appearance: Confirm that the powder is loose, without collapse or melting marks, and the color is uniform
Moisture content: Strictly control the moisture content to avoid caking or decreased activity during storage and transportation
Remelting performance: Test the dissolution rate and clarity to confirm the absence of visible insoluble substances
Tightness: Verify the sealing strength between the rubber stopper and aluminum cap of the vials to prevent vacuum failure
For sheet facial masks, attention must be paid to both the stability of the mask fabric and the essence. The following key points should be checked:
Essence: Confirm the viscosity, pH, and content uniformity, with no stratification, discoloration, or off-flavor
Film material: Verify the film weight, size, and material type, ensuring no flakes or damage
Tightness: Inspect the heat sealing strength of the packaging bag to ensure no leakage after simulating transportation vibration
Representative products for reference: niacinamide brightening facial mask, hyaluronic acid ceramide repairing facial mask, etc. Additional verification is required for the adsorption between the essence and the film to avoid the essence sinking after long-term storage
The core focus of facial cleansing products lies in balancing cleaning efficacy with gentleness, as well as ensuring stability under low/high temperatures:
Stability: It does not separate or thin at high temperatures; it does not solidify or clump at low temperatures, and returns to its normal state upon returning to room temperature
Foam performance: Test the amount of foaming and the fineness of the foam to confirm consistency with the sample
pH value: Confirm that it falls within a mild range to avoid being unfriendly to sensitive skin
Representative product reference: Nicotinamide amino acid cleanser, which requires simultaneous verification of the proportion of amino acid surfactant and cleaning performance
Face cream is a water-oil mixed system, with stratification and demulsification being the main risks. The focus of quality inspection is:
Thermal cycling test: After undergoing high and low temperature cycles, there is no oil-water separation, no coarse particles, and no discoloration
Viscosity and hardness: Confirm that the paste has a moderate consistency, is easy to spread, and feels smooth without any granular sensation
Emulsification system: Verify the type and ratio of emulsifiers, and confirm the stability of the system
Representative product reference: Niacinamide and tranexamic acid brightening face cream, which requires additional verification of the uniform dispersion of active ingredients in the emulsification system
Essence lotions have a high concentration of active ingredients, which are prone to precipitation and discoloration. Attention should be paid to the following:
Clarity: Confirmation of no precipitation, sedimentation, or suspended particles (slight characteristic color is allowed in highly active systems)
Stability of active ingredients: Verify the retention of key active ingredients after accelerated testing
pH and osmotic pressure: Ensure they fall within the skin compatibility range to avoid irritating the user's skin
Lip products come into contact with mucous membranes and have a low melting point, necessitating a focus on temperature stability and safety:
Heat resistance test: no melting, no deformation, no oil leakage at high temperatures; no cracking at low temperatures
Smell and taste: Confirmed to have no off-odors, and the flavor is consistent with the sample
Microorganisms and heavy metals: Conduct rigorous verification according to the standards for lip products to ensure compliance
Toner is mostly a water-based system, which is prone to microbial contamination and active ingredient precipitation. The key points include:
Clarity: Transparent toner is free from turbidity and sedimentation; moisturizing microemulsion system is uniform and does not stratify
pH value: confirmed to be mild and non-irritating, compatible with the skin's weakly acidic environment
Preservation system: Verify the effectiveness of preservation to prevent microbial growth during storage and transportation
Massage products need to remain on the skin surface for extended periods, necessitating a balance between lubricity and stability:
Lubricity: Test the spreadability during application and the smoothness during massage, ensuring there is no dryness or muddy residue
Stability: It does not thin or separate at high temperatures; it does not solidify at low temperatures and spreads easily
Ease of cleaning: It is confirmed that after massage, it can be easily wiped or rinsed off, leaving no residue
The core concerns of exfoliating products lie in the uniformity and gentleness of the particles. The key points for quality inspection are as follows:
Particle state: Confirm that the exfoliating particles are of uniform size and lack sharp edges and corners to avoid scratching the skin
System stability: The particles are evenly suspended without sinking or clumping, and can be easily shaken to uniformity before use
Mildness: Verify the pH value and surfactant system to avoid excessive exfoliation that may cause barrier irritation
Suppliers are required to simultaneously provide preliminary data on stability tests, including basic observations on high temperature, low temperature, thermal cycling, and light exposure tests
Maintain the sealed sample confirmed by both parties as the benchmark for subsequent bulk product comparison
For high-activity products (such as essential oils, essences, and freeze-dried powders), the testing methods and acceptable ranges for active ingredients should be agreed upon in advance
Sample by batch, giving priority to inspecting inventory batches with older production dates, to verify the stability under actual storage conditions
Conduct a rapid on-site inspection: appearance, odor, pH, viscosity, and sealability can be verified on the spot
For items requiring laboratory testing, such as microorganisms and active ingredient content, the inspection cycle and non-conformance handling plan shall be agreed upon
Suppliers are required to provide a factory inspection report for each batch, ensuring that key indicators are consistent with the contract agreements
Regularly conduct spot checks on goods in transit or at the warehouse, compare them with factory data, and assess the impact of storage and transportation processes
Conduct a review of the supplier's stability testing system on a quarterly or semi-annual basis to ensure that there are no unauthorized changes to the formula and process
Oxidation of oil and fat products: Prioritize suppliers who add a reasonable antioxidant system and use light-proof packaging materials, and shorten the shipping and warehousing cycles
Microbial contamination exceeding standards in water-based products: Focus on verifying the cleanliness of the supplier's production environment and the validation data of their anti-corrosion system
Cream and lotion stratification: Suppliers are required to provide a thermal cycling test report to confirm the stability of the emulsification system
