Application and grade assessment
We start from the formulation and the function it needs, not from a catalogue entry, and work out which composition, form and active-content basis the project would have to specify.
Rhamnolipid Biosurfactant
Project-based supply evaluation for cleaning, personal care, agrochemical and technical formulations.
Palica Chem supplies rhamnolipid biosurfactant for cleaning, personal care, agrochemical and technical formulations. We specify the grade to the application — congener profile, form and the basis its active content is stated on, not a single purity figure — and supply it with the TDS, SDS and batch documentation the destination market requires. Tell us the application, the specification or benchmark you are matching, the destination market and the expected demand, and we will confirm the grade and what ships with it. We answer for the specification we agree.
What Palica Chem Provides
What a grade can do is decided by its composition, not by its name. Four things are in scope from the first enquiry:
Specification and documentation review
We review the technical information against your requirement and supply the TDS, SDS and representative COA for the grade selected.
Evaluation samples
We send evaluation quantities against a stated grade and batch, and we say what the sample represents: a sample is only useful if it is typical of the material the supply is built on.
Commercial quotation and project supply
Quotation, packaging, quantity and lead time are confirmed after the project review rather than published in advance, and supply follows the qualification of a specific grade for a specific application.
Product Overview
Rhamnolipids are a family of glycolipid biosurfactants produced by microbial fermentation. Their structures contain rhamnose units linked to beta-hydroxy fatty-acid chains, and they are evaluated for functions including wetting, emulsification, detergency, foaming and surface-tension reduction.
A commercial grade is normally a mixture of related congeners rather than one uniform molecular species. That matters commercially: a single purity or active-content figure does not describe a grade on its own, because the congener distribution, the product form, the residual components and the analytical basis behind the number can all differ between two materials sold under the same name.
Key Product Information
| Item | General description |
|---|---|
| Product class | Glycolipid biosurfactant |
| Manufacturing route | Microbial fermentation |
| Typical composition | A defined congener or, more commonly, a mixture of related mono- and di-rhamnolipid congeners |
| Possible physical forms | Liquid, paste, powder or granular material, depending on the grade |
| CAS identification | Grade- and composition-dependent; confirmed against the SDS and specification for the grade supplied |
| Key qualification parameters | Active content and its basis, congener distribution, form, pH, colour, odour, surface activity and the application requirement |
“Rhamnolipid” can name a class of related substances, one defined congener or a commercial mixture, so a CAS number attached to a single defined molecule should not be applied to every product sold under the name. Identification follows the actual composition and the regulatory documentation for the grade supplied — our technical guide to rhamnolipids sets out how the identification levels differ and what to ask for at each.
Potential Application Areas
- Cleaning formulations — may be evaluated for wetting, emulsification, detergency and foam in hard-surface, laundry, vehicle-care, metal and industrial cleaning systems.
- Personal care development — selected grades are being developed for cleansing and solubilisation; INCI identity, sensory properties, impurities and safety documentation must be confirmed for the specific grade and market.
- Agrochemical formulations — a potential wetting, spreading or emulsifying ingredient. Use as a formulation aid is distinct from any pesticidal or plant-protection claim, which requires its own regulatory assessment.
- Selected technical applications — coatings, pigment wetting and dispersion, environmental treatment and oil-related systems, each of which can demand a different composition and cost target.
Suitability is not a property of the substance class. It has to be confirmed for the selected grade, the finished formulation and the destination market.
What We Need to Evaluate Your Project
Six things let us assess an enquiry properly. The more of them you can give, the less likely it is that a sample arrives which cannot meet the project's technical or regulatory requirements.
- Intended application and the function the material has to perform.
- Preferred physical form, or the benchmark grade you are comparing against.
- Target active-content or purity basis, if it is already defined.
- Destination country and regulatory market.
- Evaluation quantity.
- Expected order quantity or annual demand.
Grade Qualification Note
Rhamnolipid grades with the same stated active content may differ in congener profile, moisture, salt content, residual fermentation components and the analytical basis used to calculate the figure. Quotations should therefore be compared together with the grade-specific specification, representative batch data and testing in the actual formulation.
The categories a comparable specification covers, and the methods behind each of them, are set out in how to evaluate a rhamnolipid specification.
Frequently Asked Questions
Does a higher purity always mean better performance?
No. Higher purity matters for analytical, personal-care and other tightly controlled applications, but a less purified grade can be the commercially appropriate choice for a technical use. Performance, impurities, documentation and cost are judged together.
Are liquid and powder grades directly interchangeable?
Usually not without reformulation. The forms can differ in active-content basis, water or carrier content, dissolution behaviour and handling requirements.
Can rhamnolipids directly replace a conventional surfactant?
Not always on a one-to-one basis. They may serve as a primary surfactant, co-surfactant or performance additive depending on the formulation, and compatibility, dosage, foam, rheology and cleaning performance have to be tested in the complete system.
What information is needed before requesting a sample?
The intended application and function, preferred form, target specification or benchmark product, destination market and estimated demand — the six points listed above.
