Cosmetic Gloss Measurement Ver2

  1. 1. In Vivo Quantitative Evaluation of Gloss 藥妝 真 . 晶砂 真異典藏 -- 芳香療法、手工皂與化妝品 DIY 的研究世界
  2. 2. Abstract <ul><li>A real time polarization analysis technique i s described that differentiates components of scattered light in video images and enables in vivo quantitative evaluation of gloss from hair and skin during quality control and claims substantiation. </li></ul>
  3. 3. Introduction <ul><li>Cosmetic manufacturers need to quantify the visual appearance of their products objectively and accurately to study skin and hair, to improve the performance, quality and the reproducibility of cosmetic products, and to substantiate their claims. </li></ul><ul><li>In vivo non-contact testing provides the most meaningful results since it is carried out in realistic conditions directly on a model. For this article, in vivo gloss measurements were conducted on commercially available hair and skin products. </li></ul>
  4. 4. Color and Gloss <ul><li>Scattered light can be divided into three categories… </li></ul><ul><li>Mirror-like reflected </li></ul><ul><li>light (specular reflection) </li></ul><ul><li>( 鏡像反射光或鏡像反射 ) </li></ul><ul><li>Volume scattering (體積散射) </li></ul><ul><li>Surface scatteritng </li></ul><ul><li> (表面散射) </li></ul>
  5. 5. Degrees of Gloss <ul><li>Gd, ranging from 0% (low gloss) to 100% (high gloss) </li></ul><ul><li>  --The p ercentage of specular light in the          </li></ul><ul><li>   total a mount of reflected light. </li></ul><ul><li>Gd*, ranging from 0 (low gloss) to ∞ (high gloss) </li></ul><ul><li>  --The ratio of specular light divided by the </li></ul><ul><li>   volume- s cattered light in the direction of </li></ul><ul><li>   observation. </li></ul>
  6. 6. Operating Principle
  7. 7. Experimentation
  8. 8. Result <ul><li>In vivo gloss measurement of foundatio n s </li></ul>
  9. 9. Result <ul><li>Ef ficiency testing of hair product </li></ul>
  10. 10. Result <ul><li>Gloss distribution </li></ul>
  11. 11. Advantages to Gloss Measurement <ul><li>Traditional way cannot quantify accurately the gloss of complex 3D surfaces. </li></ul><ul><li>The t echnique offers non - contact in vivo measurement independent of texture and shape . </li></ul><ul><li>Correlated to human eye assessment. </li></ul><ul><li>The M ain limitation is repositioning of the object. </li></ul><ul><li>Also can use in whitening powers, radiance, soft focus power and calibrated color measurement of scattered light. </li></ul>
  12. 12. Conclusion <ul><li>The described imaging technique opens … </li></ul><ul><li>Possibility of measuring objectively the gloss of textured, complex 3D objects. </li></ul><ul><li>Well adapted for the cosmetic industry to formulate, evaluate products and substantiate claims. </li></ul>
