What Is Hydroxypropyl Beta Cyclodextrin(HPBCD)?
Cas number: 128446-35-5
Molecular weight: 1541.5 g/mol
Molecular formula: C63H112O42
HS Code: 3505100000
Other names: 2-hydroxypropyl-β-cyclodextrin, hydroxypropyl betadex, 2-hydroxypropyl-beta-cyclodextrin, hpcd, hpbcd, hpβcd, hp-beta-cd, 2-hydroxypropyl-beta-cyclodextrin ether, hydroxypropylbetadex.
Hydroxypropyl beta cyclodextrin is a white to off-white amorphous crystalline powder. It is freely soluble in water and propylene glycol. Its solubility in water is more than 100g per 100ml under 25 degrees celsius.
It is one of the most popular pharmaceutical and cosmetic excipients along with Betadex Sulfobutyl Ether Sodium. It has overcome the poor solubility shortcomings from beta-cyclodextrin. It confers solubility and stability to many APIs. The inclusion complexed can penetrate body tissues. We can biologically use them to release active compounds under our desired conditions.
What Is Hydroxypropyl Beta Cyclodextrin be used for?
The introduction of the hydroxypropyl group breaks the intramolecular cyclic hydrogen bond of β-cyclodextrin. It overcomes the main disadvantage of poor water solubility from β-cyclodextrin while maintaining the cyclodextrin cavity. It is one of the most intensively studied and widely used cyclodextrin derivatives. We will break down its usages in food, cosmetics, and pharmaceutical industries one by one.
1 In food and spice industry
It can improve the stability and long-term effectiveness of nutritional molecules. It will cover the bad smell and taste of nutritional ingredients. It greatly improves food production efficiency and quality.
As HPBCD has good solubility in water, when its substitution degree is over 4, you can dissolve it with water by any proportion. You can easily also dissolve it in 50% ethanol and methanol.
2 In our cosmetic industry
It is widely used as stabilizers, emulsifiers, and deodorants. It will help to reduce the stimulation of organic molecules in your cosmetics on your skin and mucous membrane tissues. It will also enhance the stability of active ingredients by preventing the volatilization and oxidation of nutrients. Cyclodextrins can bind fragrances, so they are able to release fragrances when heated by your skin. We can also use them to trap odor causing ingredients cover the bad smell.
Don’t forget, Hydroxypropyl Beta cyclodextrin is also hygroscopic, while we add them into cosmetics and apply to our skin, they can draw moisture to keep our skin moist.
3. Usages in pharmaceutical industry
3.1 Increase the water solubility of APIs insoluble in water
Hydroxypropyl beta cyclodextrin is easily soluble in water. What is even better, it will improve the solubility of drugs without adding organic solvents, surfactants, or lipids. It can significantly increase the water solubility of poorly soluble drugs after being enveloped with it. After the drug forms an even complex with HP-β-CD, the drug concentration increases linearly with HP-β-CD concentration.
After the complexation of baicalin with hydroxypropyl beta-cyclodextrin, the solubility of baicalin in water is increased from 0.112 mg/ml to 2.743 mg/ml, and its solubility is increased by 24.5 times.
3.2 Improve our drug stability and bioavailability
During medicine storage, we should protect our drugs from light, heat, and humidity. Those factors will directly affect the stability and quality status of our drugs. Therefore, medicine stability matters a lot. After we introduce HP-β-CD into our medicine, the active ingredients will enter the cyclodextrin cavity. The cavity will prevent APIs from volatilization, sublimation, oxidation, or photolysis.
The HP-β-CD-encapsulated drug has a faster dissolution and release rate, so it will increase the drug absorption by our body. It will improve the bioavailability of the drug encapsulated.
After estradiol is wrapped with hydroxypropyl β-cyclodextrin and stored at room temperature, its degradation half-life is extended from 1.2 years to 4 years.
After ursodeoxycholic acid is encapsulated with hydroxypropyl beta-cyclodextrin, but its dissolution is faster and more complete with the same disintegration time. Its oral bioavailability and peak concentration are increased by more than twice than those of similar ursodeoxycholic acid dosages commercially available without hydroxypropyl beta cyclodextrin.
3.3 Reduce the toxic and side effects of drugs
Complexing with insoluble drugs and change the way we take the medicine can significantly reduce the toxicity and irritation of certain drugs to our body.
Because hydroxypropyl beta cyclodextrin has a lower relative surface and hemolytic activity, not irritating to muscles, it is an ideal solubilizer and pharmaceutical excipient for injections. It can improve the water solubility of poorly soluble drugs, enhance their stability, and improve their bioavailability. It can also improve the drug efficacy with reduced dosing. We can use it to adjust or control the drug-release rate and reduce the side effects too.
It is difficult to dissolve nimodipine in water so we can not inject it but have to take it orally. But when nimodipine is taken orally, it will be absorbed in the liver first before it takes effects in our blood system. While hydroxypropyl-beta-cyclodextrin can increase the solubility of nimodipine in water by 60 times, so we can have nimodipine injections instead. Meanwhile, hydroxypropyl-beta-cyclodextrin will reduce its irritation to our muscles. Hydroxypropyl beta-cyclodextrin can also relieve the injection pain caused by etomidate if etomidate is not complexed.
We can use it for those purposes in many cases, such as voriconazole or itraconazole injections, mucosal delivery systems (nasal mucosa, rectum, cornea, etc.), transdermal absorption delivery systems, carriers for lipophilic targeted drugs, and protecting agent and stabilizer for proteins.
