Heliwet FA 35/7
What is Heliwet FA 35/7?
Heliwet FA 35/7 is a non-ionic surfactant belonging to the group of alcohol ethoxylates. The product is based on C13–C15 fatty alcohol and contains on average 7 moles of ethylene oxide (EO).
With an HLB value of approximately 12, Heliwet FA 35/7 has a balanced hydrophilic-lipophilic character. This makes it particularly suitable for:
-
Oil-in-water (O/W) emulsions
-
Industrial degreasing
-
Cleaning and detergent applications
-
Water-based technical formulations
Heliwet FA 35/7 is often selected when a formulation requires a balance between strong cleaning performance and good water solubility.

How is Heliwet FA 35/7 produced?
Heliwet FA 35/7 is produced via controlled ethoxylation of C13–C15 fatty alcohols with an average of 7 moles of ethylene oxide.
During this process:
-
The fatty alcohol reacts with ethylene oxide under controlled temperature and pressure
-
The number of EO units is precisely controlled
-
A stable, non-ionic surfactant with consistent properties is formed
The EO content determines the final HLB value and therefore the application range of the product.
Production complies with European standards, including:
-
REACH compliance
-
Control of residual monomers (such as 1,4-dioxane)
-
Batch consistency
-
Traceability of raw materials
Thanks to this controlled production process, Heliwet FA 35/7 can be reliably used in a wide range of water-based systems.
How does Heliwet FA 35/7 work in a formulation?
Heliwet FA 35/7 functions as a cleaning surfactant and an O/W emulsifier.
1. Reduction of surface tension
The product reduces the surface tension between water and oily contamination, allowing water to better penetrate grease and dirt deposits.
Example:
In an industrial floor cleaner, FA 35/7 helps to loosen oil and grease residues, making them easier to remove.
2. Emulsification of oils and fats
With an HLB of approximately 12, Heliwet FA 35/7 is positioned in the mid-hydrophilic range. It stabilizes oil-in-water emulsions and ensures that removed soil remains suspended.
This prevents redeposition of contamination on surfaces.
3. Performance in hard water
As a non-ionic surfactant, Heliwet FA 35/7 is less sensitive to water hardness than many anionic alternatives. This makes it suitable for industrial applications where water quality may vary.
In which industries is Heliwet FA 35/7 used?
The product offers a balance between oil affinity and water solubility, making it suitable for a wide range of applications.

Frequently asked questions about Heliwet FA 35/7
1. What are the benefits of Heliwet FA 35/7?
-
Balanced HLB value (±12)
-
Good degreasing performance
-
Suitable for O/W systems
-
Less sensitive to water hardness
-
Compatible with other surfactants
This makes the product suitable for both general and heavy-duty cleaning applications.
2. What is the difference between FA 35/3, FA 35/7 and FA 35/12?
The difference lies in the number of EO units and the HLB value:
-
FA 35/3 → HLB ~8 → more lipophilic
-
FA 35/7 → HLB ~12 → balanced
-
FA 35/12 → HLB ~14 → strongly hydrophilic
The choice depends on the desired emulsion type and level of water solubility.
3. Is Heliwet FA 35/7 suitable for cosmetic applications?
Heliwet FA 35/7 is primarily positioned for technical and industrial applications. Additional evaluation and documentation are required for cosmetic use.
4. When should you choose FA 35/7 instead of FA 35/12?
FA 35/7 is typically selected when:
-
Slightly higher oil affinity is desired
-
A balance between cleaning and emulsification is needed
-
The system does not need to be highly hydrophilic
FA 35/12 is more suitable for strongly hydrophilic applications.
