- Lower concentrations of titanium dioxide and silicon dioxide may be successfully used in treatment of metabolic disorders, particularly of incomplete oxidation conditions.
- High sorption of titanium dioxide and silicon dioxide hetero-crystals enables intensification of therapeutic effect: so they may be effectively used for creation of complicated pharmaceutical complexes and targeted delivery.
- High bio compatibility, no total toxicity, no local toxicity.
- High sorption effect, i.e. ability of binding target molecules.
- High catalytic reactivity, particularly high response to photochemical redox.

Three, most common natural cyclodextrins are built up from 6 - 7- and 8 glucose units. They are called alpha- and beta- and gamma-cyclodextrins. Cyclodextrins can be considered functionally as nano-sized molecular containers which can encapsulate different compounds that fit size-wise to their cavities, such as drugs, vitamins, flavors, colorants, fats, etc
The chemical modification of these natural cyclodextrins can lead to highly water-soluble cyclodextrin derivatives that can be used for making different formulations.
They can be used for making aqueous liquid formulations (eye drops, injections, infusions etc.) with poorly soluble drugs (eye drops, injections, infusions etc.) without co-solvents or detergents.
Two most important chemically modified cyclodextrins are the following:
- 2-hydroxypropyl-beta-cyclodextrin (HPBCD)
- sulfobutylether-beta-cyclodextrin (SBECD) manufactured by CycloLab Ltd. tradename Dexolve ®
There are more than 50 different liquid pharmaceutical products currently on the market based on these two cyclodextrin derivatives.
- improved chemical stability
- reduced loss during storage (longer shelf-life)
- reduced container-content interaction with packaging materials
- enhanced aqueous wettability
- improved water solubiility
- higher dissolution rates
- improved oral bioavailability enhanced therapeutic potency
This effect is particularly occurring for consumption of gamma-CD and alpha-CD, which are known to provide advantageous effects on oral uses such. These CDs can decrease postprandial hyperglycemia, reduce blood glucose levels by positively affecting polysaccharide metabolism in vivo. This is why these cyclodextrins are termed also as „dietary fibers”. As CDs are efficient lipid complexing agents, their continuous consumption may result in balanced lipid status and reduced serum cholesterol levels, leading to amelioration of atherosclerotic events.
As an example, SCHALI®-D dietary supplements – a new approach of healthy nutrition for modern humans – contain dietary fibres of Alpha-cyclodextrin (α-CD) and Gamma-cyclodextrin (γ-CD), which depending on the indicative purpose encapsulate molecules of nutrients, microelements, and vitamins: curcumin, cinnamon, resveratrol, coenzyme Q10 etc.
- Cyclodextrin complexation protects your sensitive substance, by forming non-covalent inclusion complex. This is the possible lowest level of encapsulation: the molecular encapsulation. The complexed molecules do not have an access to react within each other
PRESERVATION OF PRODUCT FRESHNESS
- Cyclodextrin-encapsulated substances will be protected against environmental factors (such as heat, light, oxygen, etc.) and so will preserve their freshness during transportation and longer storage. The product aging process will be reduced
SAFE PRODUCT PACKGING
- As product is in cyclodextrin molecularly entrapped state, and is surrounded with carbohydrate coating, it will have no physical contact with primary packaging materials. This prevents the product from leaching, from extraction from absorption with packaging polymer and other materials sheets
- Bulk cyclodextrin encapsulated substances appear as free flowing powders, or tablets or filled capsules, all with improved wettability in aqueous solutions (bulk water, fruit juices, soft drinks and alcoholic beverages)
SOLUTION FOR INSOLUBILITY
- The lipophilic, fat-soluble substances when encapsulated in cyclodextrins, will have a hydrophilic, hydration ready covering, and so the lipophilicity of the substances will be not manifested when put into water
- As the Greek philosopher, Aristotle said: „Corpora non agunt nisi fluida seu soluta” in English ‘‘Compounds do not react unless fluid or if dissolved’’. Our cyclodextrin-enabled products will have high dissolution and solubility; therefore, their biological activity will be surely achieved. This manifests as enhanced oral absorption and bioavailability and improved therapeutic potency
FIELDS OF USE
HPBCD containing hydrogel for topical administration for prevention of viral infection*
HPBCD as antiviral agent:
2-Hydroxypropyl-beta-cyclodextrin is a chemically modified beta-cyclodextrin with excellent water solubility and lipid solubilization and complexation power. This cyclodextrin derivative has a very good safety profile both upon oral and parenteral administrations. As a drug solubilizing excipient, it has been used in human drug products for over two decades. Few years ago, HPBCD has been assigned as an Orphan Drug by both US-FDA and EMA regulatory agents for the treatment of Nieman-Pick Type C, rare disease.
In our topical hydrogel products, HPBCD as an active ingredient is primarily utilized as a safe and efficient cell membrane lipids modifying agent. Since this cyclodextrin reversibly modifies and restores cell membrane lipid raft packings and lipid environment of membrane anchored glycoproteins, it disturbs and prevents viral infections against recipient cells. Membrane cholesterol plays an important role in replication of HIV-1 and other retroviruses. It was found that for instance the gammaretrovirus XMRV requires cholesterol and lipid rafts for infection and replication.
Tyng et al (see literature reference above) demonstrated that treatment of XMRV with a low concentration 2- hydroxypropyl-beta-cyclodextrin partially depleted virion- associated cholesterol, which then resulted in complete inactivation of the virus. Therefore , the topical HPBCD containing hydrogels, can be considered and recommended as novel action efficient and zero side effect antiviral compositions.
Feminine and Masculine Line of SCHALI® Care Personal Hygiene Products, where HPBCD is one of key active ingredients, is intended for antimicrobial and antitoxic protection, inducing mucosal regeneration, significantly improving cellular metabolism and promoting hormonal balance. SCHALI® Care products may be successfully used in prevention and treatment of numerous health conditions, supporting action of common therapeutic drugs and accelerating time of treatment.*Tang, YY George, A Taylor, T Hildreth, JE K et al PLOSONE October 2012 | Volume 7 | Issue 10
