Mea­sure­ment of cos­metic prod­ucts

The cos­metic indus­try is very much driven by the aes­thet­ics. A lot of spe­cial effect pig­ments are used to cre­ate light-dark and color flop. Addi­tio­n­ally, they start to sparkle when viewed in direct sun light. As many dif­fer­ent sam­ple types are used e.g. nail pol­ish, lip gloss and eye sha­dow, stan­dardized sam­ple pre­pa­ra­tion is required for repeat­able mea­sure­ment results.

Mea­sure­ment of Nail Pol­ish

A draw­down is made on a black & white test chart.
The use of BYK-Gard­ner byko-charts guar­an­tee con­sis­tent color & gloss ensur­ing that the mea­sured color dif­fer­ence only comes from prod­uct vari­a­tions. 

The ori­en­ta­tion of effect pig­ments can cre­ate dif­fer­ent looks. In the exam­ple on the right the same pig­ment was used in 2 dif­fer­ent for­mu­la­tions. In for­mula 1 the flake ori­en­ta­tion was not influ­enced. As a result it looks coarser and spark­les at a low graz­ing angle. In for­mula 2 the alu­minium flakes were ori­ented par­al­lel cre­at­ing a fine, mir­ror like look with hardly any graini­ness.
BYK-mac mea­sure­ment data clearly detects this effect by an increase in sparkle area at 75° and graini­ness.
Sparkle 75° detects the alu­minium flakes which are non-par­al­lel ori­ented.

Mea­sure­ment of Pow­dery and Pasty Mate­rials

Eye sha­dow, lip­stick / lip-gloss or facial pow­der is pressed or poured into a sam­ple cup and can be eas­ily and repeat­ably mea­sured with the BYK-mac sam­ple holder.

The holder is equipped with a mask cus­tom made to fit the aper­ture of the BYK-mac and there­fore, guar­an­tees repeat­able sam­ple place­ment and mea­sure­ment results. For sam­ple pre­pa­ra­tion the holder comes with one adapter ring and five cuvettes (Ø 35.5 mm, height 4.5 mm). 

To use it with cus­tom spe­cific cuvettes, cus­tomized adapter rings are offered.

• Max­i­mum round con­tainer size: Ø 60 mm

Eye sha­dow using the new MIRAGE effect pig­ment line from ECKART was com­pared to prod­ucts using nat­u­ral mica based pig­ments. Visu­ally, the new pig­ments distin­guish them­selves by their gla­m­orous look and extraor­d­i­nary spark­ling effect. BYK-mac mea­sure­ments of MIRAGE Gla­m­our Blue show this effect by a much higher sparkle area and inten­sity value.
