Natural biosurfactant produced by fermentation of Candida bombicola

1) What is Sopolin(Sophorolipids)?

Sopolin is a glycoplipid biosurfactant derived from microorganism, and is a natural biosurfactant produced by fermentation of Candida bombicola. Sopolin is biologically produced by the bioconversion of glucose and plant oil (or its esters) at the stationary phase of fermentation during while glycosidic bond are formed.

2) Sopolin derived from natural products

Natural surfactant produced from fermentation of natural substances including glucose, rapeseed oil, yeast extract (Saccharomyces cerevisiae) and natural substances (GMO free).

3) Chemical Structure of Sopolin

 1. Composed of hydrophile (Sophorose) + lipophile (Fatty acid)

 2. Non ionic surfactant

 3. Mixture of Acidic and Lacton form and varies depending on the fatty acids and acetyl groups of sophorose

 4. Ratio of Fatty Acids

  - Fatty acid profile of rapeseed oil, a raw material, is similar to that of Sopolin

  - Oleic acid is one of the major fatty acids.

4) Appearance of the Product

  - Transparent, dark brown liquid with characteristic order

5) Product Specification

  - pH : pH 4-6

  - Density : 1.1± 0.1

  - Water activity : 35 ± 5 %

  - Surface Tention : 38mN/m,

  - CMC : 100ppm

  - Foam : about 10% of AES

  - Dispersion Ability : Similar to SDS or Tween

  - HLB : 3-8

  - Solubility : ~10g/L in Water at Room Temperature

6) Efficacies of Sopolin

 1. Antimicrobial activity against :

  - Gram positives : Propionibacterium acne, Bacillus subtilis, Corynebacterium xerosis, Staphyococcus aureus, Streptococcus faecium

  - Gram negatives : Escherichia coli, Pseudomonas aeruginosa

  - Yeast : Candida albicans

  - Fungi : Aspergillus niger

 2. Antibacterial effect against organisms related to the dermatitis

  - Acne : Propionibacterium acnes, Staphylococcus epidermis

  - Atopic Dermatitis : Staphylococcus aureus

  - Body odor : Armpits have about one million of germ per cubic cm

    (Micrococcaceae, Diphteroide etc.)

  - Sopolin induces lysis of organisms and prevent related skin troubles and it inhibits the organism's lipolytic enzyme (lipase) to prevent unpleasant order

7) Application of Sopolin in Cosmetics

 1. Skin Care : Can easily form emulation and can be used in bacteriocidal products, acne preventing, cleansing and skin care products

 2. Hygiene : Can be used as natural deodorant, and for bath and after shaving products

 3. Hair Care : Can be used in shampoo, shower gel, tonic lotion

 4. Natural preservatives
