News Update from the Personal Care Application Laboratory

Nordmann News spoke with Laura Ratz, Senior Application Specialist Personal Care, HI&I at Nordmann, about her presentation at the SEPAWA CONGRESS on October 15, 2025, in Berlin. Under the title “Vitamin C – Stability and Performance in Cosmetic Formulations,” Laura Ratz presents innovative ingredient ideas based on the multi-talented vitamin C. From her daily work in the application laboratory, she knows what is important in modern formulations – and is constantly developing new solutions that are always in tune with the market and current trends.

Laura, why is vitamin C so popular in skin care products – and at the same time so challenging? 

 

Laura: Vitamin C is a real multi-talent: it has an antioxidant effect, helps with acne, protects against UV damage, and supports skin regeneration. The challenge, however, lies in its instability – especially in its pure form as ascorbic acid, which oxidizes easily and requires a low pH value.

What solutions do you present in your lecture to get around these problems?

 

Laura:  In addition to tips on stabilising Vitamin C, I also show various derivatives and alternatives that are more stable yet still highly effective. These include STAY-C® 50, which is significantly more stable than pure ascorbic acid, ASCORBOSILANE, a silicium combination with long-lasting and additional anti-aging effects and InnerRenewal CC+AA, which uses natural cornflower cells as a carrier system for vitamin C.

What can formulators take away from your presentation? 

 

Laura: With the right raw materials, innovative and effective products can be developed – and I hope to inspire many with our ideas and concepts. 

Visit Nordmann at the SEPAWA CONGRESS in Berlin from October 15–17 at booth A147–148.
