Soap and Surfactant-Based Products We Can Develop

The right starting point depends on the intended application, ingredient preferences, required pH, foam behaviour and desired product feel.

Explore the product groups below to identify the most suitable direction for your project.

Liquid Castile & Vegetable-Oil Soap Formulations

Develop liquid soaps around a defined vegetable-oil composition and brand positioning.

Product development options include:

• Liquid Castile Soap
• Olive Oil Liquid Soap
• Coconut Oil Liquid Soap
• Custom Vegetable-Oil Liquid Soap
• Olive & Coconut Oil Liquid Soap
• Unscented Liquid Soap
• Essential Oil-Scented Liquid Soap
• Concentrated Liquid Soap Base

The selected oils influence the finished soap’s appearance, cleansing characteristics, foam and handling properties.

We consider the proposed oil blend alongside concentration, clarity, fragrance compatibility and manufacturing requirements. Product naming and ingredient descriptions should accurately reflect the final composition.

A reference product can help establish targets for appearance, consistency and the intended user experience.

Liquid Hand Soap & Foaming Hand Wash Formulations

Create hand cleansing products for retail, hospitality, refill systems or professional use.

Product development options include:

• Liquid Hand Soap
• Foaming Hand Wash
• Fragrance-Free Hand Wash
• Essential Oil Hand Wash
• Pearlescent Hand Wash
• Clear Liquid Hand Wash
• Concentrated Hand Wash Base
• Refill Hand Wash Formulation

The formulation is developed around the intended dispenser and product experience.

A foaming pump requires a liquid with suitable flow and foam characteristics. A conventional pump may require a different viscosity and dispensing profile.

Development can consider cleansing performance, rinsing, fragrance, appearance and the desired after-feel. Any mildness or skin suitability claims require an appropriate supporting basis.

Body Wash, Shower Gel & Cleansing Bases

Develop cleansing bases for use as finished products or as a starting point for a coordinated personal care range.

Product development options include:

• Body Wash Base
• Shower Gel Base
• Foaming Body Cleanser
• Creamy Body Wash
• Fragrance-Free Body Cleanser
• Hair & Body Wash Base
• Sulfate-Free Cleansing Base
• Liquid Soap-Based Body Cleanser

These projects can involve an oil-derived soap system, a non-soap surfactant system or an appropriate combination.

The formulation approach depends on the intended use, target pH, sensory profile and ingredient preferences.

We consider how fragrance, colour, extracts and other selected additives affect clarity, viscosity, foam and stability.

Facial Cleansing & Mild Surfactant Systems

Develop facial cleansing products around clearly defined performance and sensory requirements.

Product development options include:

• Facial Cleansing Gel Base
• Foaming Facial Cleanser Base
• Amino Acid-Based Cleanser
• Glucoside-Based Facial Cleanser
• Fragrance-Free Facial Wash
• Low-Foam Facial Cleanser
• Cream Cleanser Base

Facial cleanser development requires attention to the overall surfactant system, rinsing and the desired skin feel.

Ingredient selection can include suitable glucosides, amphoteric surfactants, amino acid-derived surfactants and other cleansing ingredients, depending on the brief.

The finished formulation must be evaluated as a complete product. The use of a particular ingredient does not, by itself, establish the mildness of the final cleanser.

Household Soap-Based & Surfactant Cleaning Formulations

Develop soap-based or blended cleaning products for specified household applications.

Product development options include:

• Soap-Based Multi-Purpose Cleaner
• Liquid Cleaning Soap
• Soap-Based Floor Cleaner
• Hand Dishwashing Liquid Base
• Concentrated Surface Cleaning Base
• Refillable Household Cleaning Liquid
• Custom Soap & Surfactant Cleaning Blend

The development brief should identify the intended surfaces, water conditions, dilution and rinsing requirements.

We assess the balance between soil removal, foam, residue and ease of use. A base intended for personal cleansing is not automatically suitable for every household cleaning application.

Concentrated Cleansing Bases & Refill Systems

Develop concentrates for further processing, controlled dilution or refill-oriented product ranges.

Product development options include:

• Concentrated Liquid Soap
• Concentrated Hand Wash Base
• Concentrated Body Wash Base
• Foaming Cleanser Concentrate
• Dilutable Cleansing Base
• Bulk Soap Base for Local Filling
• Refill-Oriented Cleansing Formulation

A concentrate needs to perform both during storage and after the intended dilution or finishing process.

Development considers:

• Concentrate stability and handling.
• Viscosity and pumpability.
• Dilution water requirements.
• Mixing instructions.
• Behaviour after fragrance or colour addition.
• Preservation of the final prepared product.
• Packaging and dispensing compatibility.

Dilution ratios and finishing instructions are established for the individual formulation.

Custom Surfactant Blends & Functional Cleansing Systems

Some projects require a tailored ingredient blend rather than a finished consumer product.

We can assess briefs involving:

• Custom Cleansing Surfactant Blends
• Glucoside-Based Surfactant Systems
• Amino Acid-Based Cleansing Blends
• High-Foam Cleansing Bases
• Controlled-Foam Cleaning Blends
• Wetting & Degreasing Blends
• Soap-Compatible Surfactant Systems
• Concentrates for Further Formulation

These projects focus on the required function, processing conditions and compatibility with the customer’s final product.

Feasibility, specifications and evaluation requirements are agreed before development begins.

Choosing Between Soap and Non-Soap Cleansing Systems

Soap is itself a type of surfactant. In product development, the practical distinction is often between traditional oil-derived soap systems and cleansers made with other surfactants.

A true liquid soap and a lower-pH facial cleanser usually require different formulation approaches.

We help assess which system best fits your requirements by considering:

• Intended application.
• Target pH.
• Ingredient policy.
• Cleansing and foam expectations.
• Water conditions.
• Fragrance compatibility.
• Desired appearance and viscosity.
• Manufacturing capabilities.
• Target cost.

This assessment helps establish a realistic product brief before development begins.

Formulations Tailored to Your Brand

Your product can be developed around a defined ingredient policy and commercial position.

Project preferences may include:

• Selected vegetable oils.
• Plant-derived surfactants.
• Fragrance-free development.
• Essential oil fragrance options.
• Dye-free formulations.
• Sulfate-free surfactant systems.
• Vegan product concepts.
• Minimalist ingredient lists.
• Concentrated formats.
• Refill-compatible packaging concepts.

Each preference is assessed alongside performance, stability, preservation, sourcing and cost.

Claims such as “organic,” “vegan” or “biodegradable” need suitable documentation or evaluation. Certification requirements, where relevant, should be identified at the start of the project.
