Résumé : |
Opacifiers and pearlising agents are widely used to improve the appearance of shower gels and shampoos. Most current opacifying and pearlising solutions are based on synthetic ingredients, such as : styrene/acrylate copolymers for opacifiers, glycol stearate derivatives with fatty amides or mica-coated with a high refractive index metal oxide coating for pearlising agents.
These synthetic ingredients are in the line of fire due to current trends towards zero-plastic and zero-nano particle products. Beides, they can also be difficult to use due to pH restrictions, need for high-temperature processes, and compatibility issues with other ingredients, particularly with cationics.
This study demonstrates that a specific natural kaolin-based solution can be used to replace synthetic opacifiers and a specific natural talc-based solution can replace conventional pearlising agents. |

- METHODS : Formulations - Instrumental test : colour measurements - Instrumental test : opacity measurements - Panel test : pearlescence intensity measurements
- RESULTS : A new kaolinite mineral to replace synthetic opacifiers - An innovative talc mineral to replace pearlizing agents
- DISCUSSION : The innovative kaolin imparts opacity and whiteness thanks to its unique porous morphology - The talc-based talc pearlising agents imparts pearlescence thanks to controlled lamellarty

- Fig. 3 : Pearlising effect of two formulations measured by a volunteer panel test
- Fig. 4 : The new kaolin-based solution has a different morphology from conventional kaolin
- Fig. 5 : Compared to conventional talc the new talc-based solution has controlled multi-sheet thickness |
