1 Non-Contact Color management solutions for the cosmetics industry How do you choose a measurement instrument?
2 Challenges in Cosmetics Measuring, controlling and formulating the appearance of cosmetics products are real industrial challenges and a genuine problem due to the nature of these products in that they are commonly liquid, paste or powdered formCurrent methodologies and processes for measuring these products is to place the sample in a cuvette or petri dish and measuring through the glass or plastic using a contact based spectrophotometerWhile this process does provide repeatable results, it does not provide data that correlates with what the human eye sees, what the consumer sees in the finished product
3 Challenges in Cosmetics The human eye “sees” color based on a response to light reflecting off of the surface of the sample at a 45 degree angleThis color perception is a response to not only the reflective color of the sample, but also includes other surface appearance attributes of the sampleTotal surface appearance depends upon the texture and the gloss of the sample in addition to its color
4 Challenges in Cosmetics Typical lab based instruments use a spherical “diffuse” geometry, meaning that they illuminate with diffuse light and read the sample at 8 degrees and may or may not include the surface glossDiffuse geometry is preferred when formulating certain products, like paint, however 45 degree geometry is preferred for QCEven though 45 degree spectrophotometers are readily available, they are mostly contact based, meaning that the instrument must contact the sampleThis obviously makes measurement of powders, pastes and liquids difficult:
5 Challenges in Cosmetics Contacting these samples contaminates the instrument, which can result in costly instrument maintenance and repairA traditional method to address this problem is to place the sample in a cuvette or petri dish, and measure the sample through the glass or plasticThis method certainly addresses the contamination issue, but it does induce other errors into the measurement:Compressing these products will change the appearance of the product (ex. compressing powder into a cuvette reduces the amount of light scatter that is natural in its raw form)The glass or plastic barrier introduces a “depth of field” variable between the instrument and the sample. This becomes an error source that must be addressedThis glass or plastic barrier also introduces a first surface and second surface reflection error (typically 4% per surface) that must be accounted for.The glass or plastic barrier allows unwanted ambient light to “pipe” into the measurement area. This too, is a potential source of error
6 Challenges in Cosmetics Example of color difference of non-dairy creamer
7 Challenges in Cosmetics So, measuring through a transparent barrier, while providing repeatable results, will not correlate to the eyes natural response to the color in its natural formThe only way to truly measure a color and get a colorimetric result that correlates to the human eye is to measure the sample in its natural form, without contacting the sample, using 45 degree geometry!
8 A Revolution in Color Measurement X-rite is pleased to announce two new products that solve many of the problems related to color measurement for the cosmetics industry!A Revolution in Color Measurement
9 A Revolution in Color Measurement MA98 multi-angle spectrophotometerVS450 45/0° non-contact spectrophotometerA Revolution in Color Measurement
10 A Revolution in Color Measurement These products, when combined with our standard or customized fixtures and sample holders, provide a complete and comprehensive solution for lab analysis and evaluation, and production Quality Control for most cosmetics products including:FoundationsFree powderCompact powdersLipstickNail polishMascaraEye LinerA Revolution in Color Measurement
11 VS450VS450 is a non-contact, 45/0° spectrophotometer designed to measure all kinds of powder, paste and liquid samples in their natural form
12 VS450VS450 is the ideal product for use in production for Quality Control inspectionsCan detect change in color or surface appearance of the sample, reducing scrap and waste costs, and allowing further evaluation and analysis
13 VS450 PRODUCT FEATURES: Non-Contact 45/0° geometry Line of Sight™ targetingGloss measurementLarge and small measurement spot sizesLED illumination for long life and durabilityBest in Class color measurement accuracy
14 MA98Next generation multi-angle measurement tool designed for consistent, precise color measurement of pearlescent and other complex special effect pigmentsProvides 10 measurement angles and 2 illumination anglesMeasures according to the visual behavior of the Standard and Trial
15 MA98 Examples of 2nd and 3rd generation effect The message is that on such a sample the color you see in the "face" angle (normal to the sample) is not only depending on your observing angle but also on your illumination angle!The picture in the top left is very steep illuminated (light in the back) and the sample looks pretty greenish!The same observing condition is given in the lower left, but now the illumination is 45° where the sample looks blueish!So only a two lamp instrument according to ASTM E is capturing the full information (slides 28 to 30).MA98
16 MA98The color you see in the "face" angle (normal to the sample) is not only depending on your observing angle but also on your illumination angleThe picture top photo is very steep illuminated (light in the back) and the sample looks pretty greenish!The same observing condition is given in the bottom photo, but now the illumination is 45° where the sample looks blueishSo only a two lamp instrument according to ASTM E is capturing the full information
18 MA68II includes one additional angle (45°as-15°) detects the reddish content
19 The new MA98 using the second illumination is able to detect the turquoise / greenish look of the sample as wellMA98
20 MA98PRODUCT FEATURES:Accurate, repeatable sample positioning is obtainable with pressure feedback control and LED indicatorsPortable, lightweight, and rugged design featuring soft touch overmold case with two-hand configurationQuick reads, measurements are obtained within 2 secondsTen angles of measurement and two illumination angles allow for complete analysisStrategic design ensures aperture location and measurements that are unaffected by ambient lightCommunication available through USB or wireless (Bluetooth)
