Measuring Cosmetics With a Gloss Meter
Products that we see every single day have standards if measurement in regard to weight and size specifications, but some industries have additional specifications such as glossiness.
Flavors and fragrances are used in processed food, personal and consumer care products. With growing affluence, production of these consumer goods is rising and the use of flavor and fragrance ingredients is growing in tandem.
To meet today’s demanding consumers’ choice of good quality products, the production of flavors and fragrances is an exact science. Flavor and fragrance ingredients are primarily tested for their taste and scent functionality but there is another test parameter that is becoming more critical over the years – color.
Considerable emphasis is placed on the appearance of products by consumers unconsciously; a judgement even before taste and aroma takes place, due to color being an indication of a product’s quality. Color quality of products is maintained, by technologist conducting color tests in laboratory, so as to ensure the consistency of colors.
The Gloss Measurement Process
Even a product as simple as lipstick has a comprehensive gloss test before it reaches shelves. First, a visual inspection of the gloss will be judged by the product development team. They will analyze how the shine of the lipstick looks to the eye and possibly test what it looks like on a model. Next, the gloss will be measured by applying the lipstick to a testing surface. Here is where the Gloss Meter is used. The Gloss Meter measures the amount of light reflected back through the meter. If the number is high, the gloss is high. It also determines the uniformity of the gloss throughout the lipstick.
How the Gloss Meter Works
As stated before, the Gloss Meter measures the amount of light reflected in order to determine the level of gloss on the surface of an object. This can be done at a variety of angles, but the industry standard is 60 degrees. This angle can be used to measure any surface from matte to mirror. Most surfaces are a medium or semi-gloss, so the 60 degree measurement angle is ideal. Konica Minolta’s Uni Gloss 60Plus is a portable and affordable instrument to handle all surfaces. However, if a more tailored reading is necessary, a 20 degree angle will provide better resolution for a high gloss surface. Low gloss surfaces should be metered at an angle of 85 degrees for a more exact measurement. Konica Minolta also has a Gloss Meter with the versatility of measuring in all 3 of these degree ranges – the Micro Tri-Gloss 268.
