How should sophorolipid solids and acid-to-lactone ratio be checked?+
Sophorolipid has a solids-content specification of ≥45%; COA PGSL-260121 reports 51.3% solids. The acid-form:lactone-form ratio of 80:20 is a separate composition specification that requires matching compositional analysis. Solids content does not measure that ratio.
How is this sophorolipid produced — is it a fermentation-derived ingredient?+
Yes. It is produced entirely by yeast fermentation using a hydrophilic sugar source and a vegetable oil or fatty acid co-substrate, followed by separation, extraction, and purification of the resulting biosurfactant.
What should be tested for aqueous sophorolipid applications?+
COA PGSL-260121 records a compliant water-solubility result for the supplied sophorolipid liquid. Test performance at the actual concentration, pH, temperature, mixing process and co-surfactants. Evaluate critical micelle concentration (CMC) and finished-formulation stability separately with appropriate methods.
Can I request a free sample before placing a bulk order?+
Yes, small trial samples are available on request so that you can evaluate solids content, appearance, congener profile and performance in your own formulation before committing to a bulk order.
Do you support third-party or independent lab testing of the material?+
Yes, buyers are welcome to use an accredited third-party laboratory to independently verify solids content, the acid-form:lactone-form ratio, heavy metals and microbial limits.
Can you provide OEM or private-label services for this product?+
Yes, we support OEM and private-label supply, including customized packaging, labeling, and formulation-support discussions for qualified bulk orders.
Which pack sizes are available for sophorolipid liquid?+
Sophorolipid liquid pack options are 1 kg, 5 kg, 25 kg. Special inner-packaging, labeling and transport requirements are agreed separately for the order.
What are the MOQ and pack options for sophorolipid liquid?+
The raw-material MOQ for sophorolipid liquid is 1 kg, with pack options of 1 kg, 5 kg, 25 kg. Quote comparisons should distinguish total liquid mass, solids content and composition specifications.
How should buyers define HLB requirements for sophorolipid?+
Define sophorolipid HLB requirements with the acid/lactone and congener composition, measurement or calculation method, and intended emulsion system. This supplied grade has no numeric HLB release specification. If an HLB value is required, agree the method and supporting data separately; the 80:20 ratio alone cannot supply it.
How should acidic and lactonic sophorolipids be compared as emulsifiers?+
Compare acidic and lactonic sophorolipids at matched oil phase, level, pH, salt concentration, co-surfactants and emulsification process. Assess droplet size, separation and storage stability. Select the grade using controlled tests in the intended formula; one study system does not establish performance in another.
Does 45% solids mean 45% pure sophorolipid?+
No. Solids content and chemical purity are different measurements. PathGene batch PGSL-260121 reports 51.3% solids against a ≥45% solids specification; it does not report 51.3% chromatographic sophorolipid purity.
Which tests are needed for sophorolipid demulsification projects?+
Define the emulsion composition and separation target, then test sophorolipid level, mixing, temperature and settling time against controls. Measure phase separation and residual oil or water. Agree demulsification performance from the actual system’s test data, rather than substituting a release COA for application trials.
Can sophorolipid replace a cleanser surfactant or preservative one-for-one?+
Replacement requires matched solids/active-content basis and the actual acidic/lactonic composition. Compare foam, cleaning, viscosity, separation and preservation in the finished formula. An antimicrobial prototype does not establish preservative-free performance; ≥45% solids is not a chromatographic-purity claim.
