The Quality Behind the Quality: Delving into Our Key Metrics

20. October 2023

The term “quality” isn’t just a buzzword, it’s the very bedrock of what we do. To ensure the consistently high standard of our natural ingredients, we rely on the rigorous tracking of specific metrics.

IOI Oleo GmbH is renowned for its top-tier products. We firmly believe that enduring, reliable and long-term partnerships are only formed on the foundation of consistently high quality. This is especially true given that our emollients, emulsifiers and multifunctionals often form the basis of cosmetic formulations.

Our comprehensive monitoring encompasses Acid Value, Hydroxyl Value, and Saponification Value. Here’s what these KPIs indicate:

The Acid Value is a pivotal quality factor that signifies the stability of a lipophilic product. All of IOI Oleo GmbH’s offerings are ester products, some with shorter fatty acid chains. The shorter the chain, the tougher it is to achieve a low Acid Value and thus produce a stable product. This stability — or a low Acid Value — affects the product’s shelf life and ensures it has minimal inherent odour and taste.

The Hydroxyl Value depicts the count of free alcohol groups (OH groups) in a product. This metric offers insights into product composition. Unlike the Acid Value, every molecule has its unique Hydroxyl Value, which means that a lower value isn’t necessarily better. For instance, triglycerides typically have a lower Hydroxyl Value, whereas monoglycerides possess a higher one.

The Saponification Value serves as another marker to characterize lipophilic products. It’s determined by the sum of the Ester and Acid Values (Saponification Value = Ester Value + Acid Value). Depending on its molecular size, free fatty acids, and esterification degree, a lipophilic product will exhibit a specific Saponification Value. A value within a narrowly defined range signifies a high-quality product.

Quality Pursuit: An Ever-Evolving Journey

Achieving and upholding top-notch quality isn’t a one-time feat — it’s a continuous  endeavour. For us, pinpointing and integrating reliable metrics isn’t just a formality; it’s a vital tactic for the consistent reproduction of superior quality in our production processes.
