| Delivery Systems |
| Our laboratories in Toulouse, France specialize in the research and development
of delivery systems made from natural ingredients for the delivery of cosmetic actives. Submicron patented products such as Glycospheres® allow a limited penetration and a protection of labile molecules. Softspheres®, another patented technology, are large and colorfull visible particles, but are intended for the decoration of cosmetic products. They rub out easily, leaving no residue. Skin care patches will be the best choice when a precise control of the delivery is necessary. |

| Glycospheres |
| Glycospheres®
are supramolecular systems, which consists of a stable inner core, made of starch, and lipids layers
(fatty acid esters and polar lipids), organized around this core.
The small size (200 nanometers) of this spherical system allows a controlled penetration
in the first layers of the epidermis. Both hydrophilic and lipopilic active ingredients can be entrapped in the Glycospheres®. Experiments on ascorbic acid, free-radical scavengers, enzymes or antibacterial agents have shown that entrapped actives are more stable than the non-entrapped form, and remain active after entrapment and delivery. |

| Softspheres |
| Softspheres® are large spherical (0.7 to 2 mm) particles used for the decoration of formulas and the delivery of lipophilic and / or anionic active ingredients. Made of agar-agar, they are soft enough for being crushed on the skin without leaving any residue. To this agar matrix a copolymer, cationic and amphiphilic is added, which is able to trap active material (natural oils, proteins, vitamins, fragrances, ...) and colorants within the sphere. |

| Skin Care Patches |
| The use of Skin Care Patches for the delivery of cosmetic active ingredients
allows a better control of the area of application, the time of application, the amount of active
delivered to the skin, because the actives are released at a more constant rate. Daily applications
can also be reduced. Patches are able to protect unstable active compounds in formulations. Kobo Skin Care Patches use two different matrices : hydrogels for short term use, and lipophilic matrices for overnight / long-lasting effects. Different forms and sizes are available as is custom manufacture and pouch printing and labeling. Please note Skin Care Patches are only available through Kobo Products sas in France : contact them at this e-mail address. |
