Science
Mechanism of Action
This ingredient functions primarily as a sophisticated biosurfactant, effectively reducing surface and interfacial tension within formulations to ensure stable emulsion formation and enhanced cleansing. On a biological level, it actively promotes skin hydration and elasticity, contributing to improved texture, softness, and a radiant complexion. It nourishes the skin and reinforces the skin's natural barrier, particularly beneficial for revitalizing dry areas. The ferment exhibits antiseborrhoeic properties, aiding in sebum regulation, and acts as an antimicrobial agent, notably against Cutibacterium acnes. It also provides protective benefits against environmental stressors, demonstrates antioxidant and anti-inflammatory capabilities, supports wound healing, and can enhance the transdermal permeation of other active molecules, all while remaining gentle on the skin and respecting its natural microbiome and pH balance.

Dusting Analysis
This ingredient demonstrates measurable efficacy at concentrations as low as 0.01% in controlled in-vitro studies. Given its established benefits even at low inclusion rates and a broad safe usage range extending up to 30%, it is not commonly associated with 'dusting' practices in cosmetic formulations, as effective concentrations are readily achievable.
The Formula
Formulation
Stability
The acidic sophorolipid form, characteristic of this hydrolyzed extract, exhibits excellent water solubility and is stable within a mildly acidic to neutral pH range, optimally around pH 6 ± 0.5%. It is highly effective in forming stable oil-in-water emulsions, leveraging its biosurfactant properties to solubilize oils efficiently.
Synergies
- Enhances transdermal delivery and permeation of other active ingredients without altering their intrinsic properties.
Safety
Safety Profile
Generally regarded as safe, non-toxic, and eco-friendly. Studies indicate low cytotoxicity to human keratinocytes and skin dermal fibroblasts. The related ingredient 'Candida Bombicola/Glucose/Methyl Rapeseedate Ferment' holds a 'LOW' hazard rating from EWG for concerns including cancer, immunotoxicity, and reproductive toxicity. While older animal tests described some sophorolipid forms as 'slightly irritating', more recent and specific data consistently conclude this ingredient to be 'non-irritating'. No significant oral, dermal, or inhalation toxicity has been identified through general GHS classifications.
