Evaluating Color Retention Using Spectral Analysis
Hair product manufacturers have developed formulas that seek to decrease the wash-out rate of dyes and improve color retention by using surfactants and conditioning agents that protect against color fading. conditioning agents such as cationic and specialty silicone polymers can significantly improve color retention as well as offer additional sensory, aesthetic, and protective benefits. However, the chemical and physical properties of these conditioners must be considered to ensure compatibility with other ingredients, particularly organic materials such as natural waxes, oils.
To evaluate the efficacy of both individual color retention ingredients and hair product formulations, an objective basis of color measurement must be employed to accurately quantify product behavior. Spectral analysis using spectrophotometric instrumentation is considered the gold standard in hair color analysis and is the first choice for evaluating color change in response to shampooing, conditioning, or treatment. Spectrophotometers are ideally suited for providing objective color data to precisely identify even slight color variations and allow you to develop a fully articulated picture of a product’s functionality. By taking baseline measurements of newly dyed hair samples and comparing them to measurements after each washing, conditioning, or treatment event, you can clearly track color changes and observe the rate of color loss over time to correlate color changes to specific individual ingredients or test the efficacy of a completed product. As a result, you can more precisely tailor formulations to enhance color retention as well as produce accurate, evidence-based claims to market your product.
We have special port for our spectrophotometers to hold hair swatches for measurements. It helps user to place the samples appropriately to perceive valid readings. this port is specially designed for cosmetic Industry users to make their measurement method standardized to perceive accurate readings.
