Course Description

Optimize your current siloxane formulations - learn when to keep, reduce, or replace siloxanes to meet evolving regulatory and market demands without sacrificing performance. With upcoming EU restrictions on D4, D5, and D6, rethink your approach to ensure compliance while maintaining aesthetics, spreadability, and sensory appeal.


Join industry expert Eric Abrutyn to gain practical strategies and formulation insights:


  • Navigate evolving regulations – Stay ahead of the 2026 EU restrictions on D4, D5, and D6, and learn how they impact different applications.
  • Strategic reduction techniques – Discover how to minimize siloxane content while maintaining product performance, compliance, and consumer acceptance
  • Smart replacement strategies – Explore viable non-siloxane alternatives that deliver similar aesthetics, feel, and functionality.
  • Real-world formulation insights – See how leading brands are adapting with case studies and formulation examples across skincare, hair care, sun care, and deodorants.

Why should you view this course?

While siloxane chemistry remains essential in cosmetics, the industry is facing increasing pressure to reduce or replace it due to evolving regulations and shifting market expectations. The challenge? Maintaining the same level of performance, spreadability, and sensory experience without siloxanes—or at least with a reduced amount.

This course provides a practical roadmap to help you navigate this transition strategically. You’ll learn how to optimize siloxane use, meet compliance requirements, and explore viable alternatives that align with both performance and consumer expectations.

  1. Understand the unique chemical and physical attributes of methyl siloxy siloxane technologies and how they differ from carbon-based alternatives in terms of volatility, spreadability, and performance.

  2. Navigate the latest EU regulatory changes affecting siloxane use, and restrictions on D4, D5, and D6, and develop strategies to stay compliant while maintaining product quality.

  3. Optimize siloxane use in formulations—learn when to reduce, replace, or modify siloxane content to meet regulatory and market demands without compromising aesthetics or functionality.

  4. Find the right non-siloxane alternatives based on formulation needs, ensuring minimal reformulation challenges while maintaining sensory experience and stability.

  5. Gain formulation insights from real-world applications, exploring how leading brands are adapting siloxane technologies across key personal care categories, including skincare, sun care, hair care, antiperspirants, cleansers, and facial makeup.

Who should join this course?

  • Formulating chemists who are looking to enhance their current formulations and find alternatives to siloxanes.

  • Marketing and ingredient suppliers who want to better position their non-siloxanes in the market.

  • R&D engineers looking to delve into non-siloxanes for their cosmetic products.

  • Complete the course and (unlock your personalized certificate)– your badge of accomplishment awaits!

  • This course is suitable for intermediate level proficiency
