1: What is pullulan:

Pullulan is naturally occurring, as a cell wall component for organisms such as fungus  Aureobasidium pullulans.
Pullulan is produced from starch by the fungus Aureobasidium pullulans.
As an edible, bland and tasteless polymer, the chief commercial use of pullulan is in the manufacture of edible films that are used in various breath freshener or oral hygiene products such as Listerine Cool Mint PocketPaks. As a food additive, it is known by the E number E1204.

2: Chemistry:

CAS number [9057-02-7]; Molecular formula (C6H12O5)n
Pullulan is a polysaccharide polymer consisting of maltotriose units, also known as α-1,4- ;α-1,6-glucan. Three glucose units in maltotriose are connected by an α-1,4 glycosidic bond, whereas consecutive maltotriose units are connected to each other by an α-1,6 glycosidic bond.

3: Why pullulan:

The reason that we choose pullulan is due to following factors:
1): Pullulan is more natural, involving no toxic chemicals, much less environment polluting in its production process
2): Pullulan possesses more potential for price reduction when produced in mass, because the fermentation technology used is widely used and very mature.
3): Pullulan film is 300 times stronger oxygen barrier than HPMC film, 9 times stronger than gelatin film
4): Pullulan is much more inert than gelatin or HPMC, so there is no interaction with products it intended to deliver.

4: How pullulan is made:
Commercially, Pullulan is from fermentation process. Aureobasidium pullulans grow on the carbohydrate substrate (sugar or starch. ThenAureobasidium pullulans is harvested. Followed by rupture the cell  with either enzyme or physical force. Pullulan then is extracted using simple water extraction process. There are no environment damaging waste, or carcinogenic material used.

Silicone elastomer

General Properties:

Good mechanical properties
Low compression set at elevated temperatures
Heat stable (indefinitely up to 180ºC)
Flexible at low temperatures (-40ºC)
High dielectric strength
Low flammability
Can be food grade compliant
Probably the single most important characteristic of silicone elastomers is their unique ability to retain their mechanical properties over a wide temperature range.

General Applications:

Construction: sealants, structural glazing
Moldmaking: prototyping, restoration, furniture, ornaments
Household: gaskets, o-rings
Automotive: cure-in-place gaskets, vibration dampers
Electronics: adhesives

Condensation Cure RTVs:

Probably the most widely used cure chemistry in RTVs is that of condensation cure. One of the key features of condensation cure is that of being hard to inhibit by most pollutants in the application environment.

These systems consist of one (RTV-1) or two (RTV-2) components. In the case of RTV-1, the product will cure upon exposure to moisture in the air as it is applied out of its package. In the case of RTV-2, the curable composition is formed by mixing two components during application.

RTV condensation cure systems are prepared from silanol-terminated PDMS, crosslinker and catalyst; reinforcing fillers and pigments are common additives.

There are four major cure systems in use related to the nature of the crosslinker: acetoxy, alkoxy, amine and oxime. The corresponding split products are acetic acid, alcohol, amine and oxime, respectively. Common catalysts are organotin and organotitanate.

As mentioned above, the reaction is carried out in the presence of moisture with evolution of the corresponding split product to form siloxane bonds in a tri-dimensional network.



Arbutin is a type of hydroquinone glucoside with a α-glucosyl bond. It is a functional active ingredient for skin lightening. Arbutin blocks epidermal melanin biosynthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa.

Arbutin can promotes lightening and an even skin tone on all skin types, minimize liver spots and reduce the degree of skin tanning after UV exposure. Both of alpha and beta form are available.

Magnesium Ascorbyl Phosphate

Magnesium Ascorbyl Phosphate (MAP)

MAP is a water-soluble derivative of vitamin C rapidly gaining popularity in skin care. It is nonirritating and more stable than vitamin C. Most importantly, magnesium ascorbyl phosphate appears to have the same potential as vitamin C to boost skin collagen synthesis but is effective in significantly lower concentrations. Overall, magnesium ascorbyl phosphate appears to be a better choice than vitamin C for people with sensitive skin and those wishing to avoid any concomitant exfoliating effects.

Kojic acid/ Kojic dipalmitate

Kojic acid Kojic dipalmitate

Kojic Acid and its derivatives inhibit the activity of tyrosinase present in human skin so as to inhibit the melanin formation and produce excellent effects in whitening skin and in anti-suntan.

Kojic Acid is water soluble and its dipalmitate is oil soluble which is more easily absorbed into skin.
