Biodegradable opacifier for pure and renewable cleansing formulations

Mackadet® OPR-2 is a biodegradable solution for cleansing products that give a creamy white appearance to formulations. This innovative technology answers the consumer demand for pure, simple and renewable cosmetic formulations.

 

New customer expectations 

Environmental impact and ingredient safety are two rapidly growing concerns in the personal care market. This “clean beauty” trend is driven by consumer demand for products formulated with ingredients that are sustainably and ethically sourced and produced with personal and environmental health in mind. The multifaceted nature of the clean beauty trend poses a much greater challenge than merely offering a selection of products containing fewer chemical ingredients. Formulators are now challenged with developing eco-conscious formulations with naturally based, renewable and high-performing ingredients.

The clean beauty trend signals the declining use of synthetic ingredients like styrene acrylate copolymers in today’s personal care solutions. Now, how do we answer this new market demand?

The SPM global and systematic assessment helps alert the business to sustainability market signals, even weak ones, to anticipate their impact and develop the right answers in a timely way. It enables value to be captured in emerging eco systems and helps business to grow its portfolio by levering on opportunities and turning challenges into solutions. 

 

Sustainable alternative to synthetic ingredients

Mackadet® OPR-2 from Solvay is a superior, next-generation ingredient for use in opacifying power systems designed as an alternative to synthetic, acrylate-based ingredients. Mackadet® OPR-2 is a biodegradable and naturally derived solution Index of naturality Ino (ISO 16128-2 standard) of 0,91% that gives a “creamy” white and caring appearance to cleansing product formulations. Mackadet® OPR-2 delivers high-opacifying efficacy that is easy to formulate and suitable for sulfate-free formulations. This innovative, highly efficient, bio-based technology is a stark alternative to synthetic ingredients, such as styrene at different levels (biodegradability, natural index, opacifying, etc.), and meets the growing consumer demand for sustainable alternatives to styrene acrylates.

Strong opacifying performance 

A spectrocolorimeter was used to measure opacifying performance. The L white index correlates to whiteness. When the L white index is high, the covering effect will be high as well. To match the performance of styrene acrylate at 1%, Mackadet® OPR-2 was used as 1,8%. The covering effect increased with the dosage of Mackadet® OPR-2, but reached a threshold at 2,8% as is. Only 1.8% of Mackadet® OPR-2 is needed to achieve the performance of styrene acrylate at 1%. 

If the viscosity of the final formulation requires a minimum viscosity of 3000 cps, adding a rheological agent is not necessary.

Colorful results

With the whitest-white chassis of Mackadet®  OPR-2, the color of a formulation is whiter and more intense when compared to using styrene acrylate as a base chassis.
