Steareth-2 and Steareth-21 provide a balanced emulsifying system for robust, stable and elegant formulations. Ideal for both water-in-oil and oil-in-water emulsions, these ingredients enhance texture, stability and performance.

In a world where skincare is often marketed through extremes, it’s easy to assume that higher strength automatically means better results. But real skin health isn’t built on intensity it’s built on understanding how skin functions over time.

Science-led skincare focuses on balance, tolerance, and long-term performance. Thoughtful formulation respects the skin barrier, supports natural resilience, and delivers results that don’t come at the cost of irritation or damage.

Instead of overwhelming the skin, smarter skincare works with biology, creating consistency rather than short-lived reactions. This approach is key to achieving skin confidence that lasts.

At Certiderma, we believe evidence-based formulation is the foundation of effective skincare. 🌐:https://www.certiderma.com/

Measure and control surface tension for better product performance, stability, and quality with Orbit Research's precision instruments

Optimize Your Formulations with Accurate Surface Tension Measurement

Surface tension is a fundamental physical property of liquids describing the surface's cohesive forces. It allows the surface of a liquid to behave like a stretched elastic membrane, resisting external forces. Understanding and measuring surface tension is critical in a wide range of industries, especially those involving formulation and quality control.

🔬 Why Surface Tension Matters

Surface tension plays a crucial role in how liquids behave in contact with solids, and other liquids, It directly influences key behaviors such as:

Spreading and wetting

Foam formation

Emulsion and suspension stability

Detergent and surfactant efficiency

Droplet formation and spraying behavior

🧴 Applications in Everyday Products

We encounter the effects of surface tension in many daily-use products and processes. Some notable examples include:

Personal Care: Soaps, shampoos, creams, and lotions depend on controlled surface tension for proper spreadability, texture, and skin feel.

Household Cleaners: Detergents and surface cleaners rely on surfactants to reduce surface tension and enhance cleaning efficiency.

Beverages: In products like branded juices, soft drinks, and beer, surface tension influences foam stability, mouthfeel, and visual appeal.

Pharmaceuticals: Suspensions and emulsions require precise surface tension control to ensure stability and bioavailability.

Printing and Coating: Proper wetting of inks and coatings depends heavily on surface tension characteristics.

Agrochemicals: Spraying efficiency and leaf wetting are determined by the liquid’s surface tension.

⚗️ Role of Surfactants

Surfactants are compounds added to reduce the surface tension of liquids. The right surfactant formulation helps achieve the desired product performance—whether it's better spreading on a surface, improved emulsification, or enhanced foaming properties.

Formulators use surface tension measurement to:

Determine the Critical Micelle Concentration (CMC)

Optimize surfactant concentration for cost-effectiveness.

Compare the performance of alternative ingredients or suppliers.

📏 How Surface Tension is Measured

Surface tension is typically measured in milliNewtons per meter (mN/m) using advanced techniques such as:

Du Noüy Ring Method

Wilhelmy Plate Method

Pendant Drop Method

These methods are chosen based on the static measurements required. Instruments like tensiometers provide accurate, repeatable results, making them essential tools in both R&D and quality control environments.
