The client is SWISS PURE, a premium Swiss luxury skincare brand specializing in anti-aging repair, sensitive-skin exclusive and organic natural skincare lines distributed to high-end department stores and private custom channels across Switzerland, France, Monaco and other European regions, targeting high-net-worth sensitive-skin consumers. For this project, they purchased high-purity acid-type sophorolipids (≥95%) for premium repair emulsion, soothing cleansing lotion and organic body lotion with core demands as follows:
· Formula Requirements: Low-temperature stability, high emulsification efficiency, compatibility with plant essential oils, low irritation.
· Production Requirements: Compatible with European emulsification equipment, low foam and easy defoaming, stable batch consistency, direct feeding suitability.
· Quality Requirements: Palm oil-free, free of synthetic residues, compliant with ECOCERT organic and CosIng standards.
This was the client’s first industrial application of sophorolipids. After purchasing standard-grade products from a major domestic manufacturer, three consecutive batches suffered formula failures, production bottlenecks and quality fluctuations, risking delayed new product launches, scrapped formulas and brand reputation damage. They urgently entrusted HiSiaddi with technical diagnosis, formula optimization, production adaptation and full-process technical implementation.
1. Poor formula stability: Low-temperature stratification, high-temperature discoloration and essential oil incompatibility
· Low-temperature stratification: Repair emulsion separated and released water after 7 days refrigeration at 4°C with a demulsification rate ≥30%.
· High-temperature discoloration: Samples turned yellow-brown after 15-day accelerated testing at 45°C with a color difference ΔE＞5.
· Essential oil incompatibility: Flocculation and agglomeration occurred after adding 2% chamomile essential oil, preventing stable emulsion formation. Root Cause: Standard products were acid-lactone mixtures (75/25 ratio) with purity of 88%, residual palm oil fatty acids and high acetylation residues, causing fluctuating HLB values, uneven emulsification and poor compatibility.
1. Poor production adaptability: Excessive foam, difficult defoaming, wall adhesion and equipment residue
· Severe foaming: Stirring generated foam heights ≥30cm requiring 30 minutes of defoaming, cutting production capacity by 40%.
· Severe wall adhesion: Sophorolipids adhered to reactor walls and agitator blades with residual volume ≥15%, causing high batch losses and difficult cleaning.
· Slow dissolution: Dissolution time in 25°C water exceeded 60 minutes, requiring additional heating to 40°C, raising energy consumption and compromising active ingredient efficacy. Root Cause: Conventional manufacturing processes lacked deacetylation treatment, retained high bacterial protein residues and uneven particle size distribution (50–500nm), resulting in excessive surface activity, high viscosity and poor dispersibility.
1. Batch quality fluctuations: Unstable purity, variable impurities and inconsistent performance
· Purity fluctuations: Three batches delivered purity ranging from 85% to 89% with acid-type ratios between 70% and 78%, creating emulsification capacity differences ≥20%.
· Interfering impurities: Batch-to-batch variations in residual palm oil fatty acids, polysaccharides and bacterial proteins caused fluctuating irritation levels and microbial risks. Root Cause: Manufacturers adopted crude fermentation processes (32–35°C temperature, uncontrolled pH) with only single-stage extraction purification and no online quality control, leading to uncontrolled batch consistency.
1. Technical communication barriers: Poor compatibility with European formulation systems and non-standard test data The client’s senior Swiss formulation experts adopted European cold-mix/low-temperature emulsification systems requiring standardized English data including precise HLB values, critical micelle concentration (CMC), interfacial tension and compatibility parameters. The original supplier lacked professional testing capabilities, incomplete technical documentation and weak English communication skills, unable to deliver formula adaptation parameters, production operation guidelines or troubleshooting solutions, leading to recurring unresolved issues.
HiSiaddi assembled a dedicated team of sophorolipid application engineers, cosmetic formulators, production process specialists and Swiss-language technical support staff, adopting a five-step solution: Problem Diagnosis → Raw Material Modification → Formula Optimization → Production Adaptation → QC Standardization, completing technical rectification in 14 days and stable mass production in 21 days.
· Raw Material Analysis: Tested original products for acid/lactone ratio (76/24), purity (87.2%), residual palm oil (3.8%), acetylation degree (12%), particle size (120–450nm), interfacial tension (35.6 mN/m) and CMC (0.08%).
· Formula Simulation: Replicated the client’s repair emulsion formula (2% sophorolipids, 2% essential oil, 5% glycerin, water balance) to reproduce 4°C stratification, 45°C discoloration and essential oil flocculation issues.
· Production Simulation: Conducted tests under the client’s 300L emulsification reactor conditions (300rpm, 25°C cold mixing) to reproduce 32cm foam height, 18% wall adhesion and 72-minute dissolution time. Conclusion: Core bottlenecks stemmed from high lactone content, insufficient purity, excessive impurity residues, uneven particle size and overstrong surface activity, requiring customized modified high-acid sophorolipids paired with minor formula adjustments and optimized production parameters.
Structural Optimization
· Lactone Conversion: Enzymatic deacetylation + low-temperature acid hydrolysis reduced lactone ratio from 24% to ＜3% with acid-type content ≥97%.
· Deep Purification: Two-stage ultrafiltration (30kDa→10kDa), activated carbon decolorization and vacuum low-temperature drying raised purity to 96.8%, eliminating palm oil residues (＜0.1%), bacterial proteins and polysaccharides.
· Particle Size Regulation: High-pressure homogenization concentrated particle sizes within 80–150nm, boosting dispersibility by 40%.
Customized Performance Tuning
· HLB value adjusted to 14.2 (optimized for premium oil-in-water emulsions).
· Interfacial tension lowered to 31.5 mN/m with CMC reduced to 0.03% (efficient emulsification at low addition rates).
· Controlled foam height ≤8cm (low-foam formulation ideal for cold mixing, easy defoaming). Deliverables: Full English test reports covering purity, acid-type ratio, residual content, particle size, surface activity, microbiology and heavy metals, compliant with ECOCERT and CosIng standards.
Minor Base Formula Adjustments
· Sophorolipid dosage reduced from 2.0% to 1.5% (high-purity high-efficiency formula cuts foam and viscosity).
· Essential oil pre-treatment: Pre-dissolve 0.5% sophorolipids with essential oils to avoid flocculation upon direct addition.
· Thickener system optimization: Adjust xanthan gum from 0.15% to 0.1% with 0.05% guar gum to enhance low-temperature stability.
All Stability Tests Passed
· 4°C/7 days: No stratification, water separation rate ＜1%.
· 45°C/30 days: ΔE＜1.5 with zero discoloration.
· Cold-heat cycles (-10°C ↔ 45°C, 5 cycles): Stable without demulsification.
· Essential oil compatibility (2% chamomile/lavender): Uniform transparent emulsions with no flocculation. Efficacy Verification: Zero irritation human patch testing, ≥99% bacteriostatic rate against Propionibacterium acnes, 15% improved repair efficacy.
Adjusted Feeding Processes
· Warm water pre-dissolution: 30°C purified water (instead of cold water) shortens dissolution time to 15 minutes.
· Stepwise feeding: Pre-mix sophorolipids + glycerin for 5 minutes before adding aqueous phase to avoid direct reactor wall contact.
Defoaming Solution
· Low-foam modified raw material (foam ≤8cm) eliminates demand for extra defoamers.
· Reduce stirring speed from 300rpm to 200rpm to lower foam height ≤5cm with defoaming time ＜5 minutes.
Wall Adhesion Resolution
· Optimized raw material viscosity via particle size regulation and impurity removal cuts wall adhesion residue to ＜3%.
· Pre-coat reactor walls with thin glycerin layers to further reduce sticking. On-Site Guidance: HiSiaddi engineers stationed at the client’s Swiss factory for 1 full day to supervise feeding, temperature and stirring control, resolving operational details and achieving successful one-off trial production.
