Monitoring colour formulas in self tanners
Long gone are the days when the only option for self tanners were the ones that gave you that hideous bright orange glow that clearly resembled one of the Oompa-Loompa’s from Willy Wonka’s chocolate factory. Today’s self-tanners are comprised of specific colour formulas that are carefully monitored with colour measurement technology. Spectrophotometric technology allows for precise quantification of the active self-tanning ingredient, DHA (dihydroxyacetone). The chemical compound in DHA directly affects pigmentation changes in the skin. These changes are measured by percentage of DHA, and a higher percentage value relates to a darker, tanned appearance. Spectrophotometers are a simple and effective method of DHA analysis, which provides the quantifiable data needed for proper labeling and regulations required by the FDA (Food and Drug Administration) for cosmetic products.
With more and more consumers turning to sunless tanner as an alternative to the damaging UV rays of the sun, the market competition has increased significantly over the last several decades. In fact, according to CNN Money, self-tanning is one of the fastest growing markets today. With competition rising, companies are working hard to create the best self-tanning colour formulas in order to outmatch their competitors. Spectrophotometers are essential when measuring natural skin colour tones to skin tones where artificial tanning products have been applied. The consumer desires a “natural look” and will spend extra on a product that provides this need. Not only do spectrophotometers measure skin tones and create accurate comparisons, but they also provide the numerical data needed to recreate these colour formulas repeatedly. Customers demand this level of quality in their products and trust brands that provide consistent results every time.
Quality and purity
The active ingredient in self tanners is still DHA, but new additives such as UV skin protectants and alpha-hydroxy acid are now being added to the colour formulas to increase functionality of the product. With these new additives come the risk of other unwanted products making their way into the formula. According to the FDA (Food and Drug Administration), “the regulations listing DHA as a colour additive also require it to meet tight specifications, with strict limitations on impurities.” Spectrophotometric technology meets the standards in impurity analysis and is highly effective in measuring chemical compounds for unwanted substances, making it a valuable tool in self tanner formulation monitoring and quality control.
