What are the solubilizing agents?

In this study, 5(6)-carboxyfluorescein (CF) and fluorescein isothiocyanate-labeled dextran (MW 4400, FD4) were used as model compounds to examine the effects of twelve common solubilizing agents, sodium taurocholate (NaTC), Labrasol, polyethylene glycol 400 (PEG 400), Transcutol P, propylene glycol, Gelucire 44/14, HCO …

How do solubilizers work?

As the name reveals, a solubilizer is an ingredient that helps solubilize (make soluble) an ingredient which is otherwise insoluble in a medium. The best and most widely application of a solubilizer (specially in natural cosmetics) is to solubilize and to uniformly disperse an essential oil in water based products.

What is solutol used for?

Kolliphor® HS 15 (formerly regarded as Solutol® HS 15) a non-ionic surfactant, has been used as a solubilizer in parenteral and oral formulations for over several decades.

Is glycerin a solubilizing agent?

Glycerin is miscible with water, alcohol, propylene glycol, and polyethylene glycol 400. As a solvent, the solubilizing properties of glycerin are comparable to alcohol but because of its viscosity, solutes are slowly soluble in it unless it is rendered less viscous by heating.

What is Cosolvent and examples?

The most pervasive is the application of non-toxic cosolvents with water to produce formulations that can dissolve hydrophobic molecules while maintaining cohesion with biological systems. Common cosolvents for this purpose are ethanol, propylene glycol, glycerine, glycofural, and polyethylene glycols.

Which is used for solubilization?

VIII. Solubilization is the formation of a thermodynamically stable, isotropic solution of a substance (the solubilizate), normally insoluble or slightly soluble in water, by the addition of a surfactant (the solublizer).

What are natural solubilizers?

Different from synthetic solubilizers, natural solubilizers are derived entirely from naturally occurring sources. They activate the utility of essential oils in water-based cosmetics by solubilizing them without damaging their nutrients.

What is Solubol?

The Solubol is a natural dispersant, alcohol-free and virtually odorless, which allows to emulsify essential oils in water. It can be used for a preparation for oral use or for the preparation of a bath.

What are excipients?

Pharmaceutical excipients are substances that are included in a pharmaceutical dosage form not for their direct therapeutic action, but to aid the manufacturing process, to protect, support or enhance stability, or for bioavailability or patient acceptability.

What happens when glycerin is mixed with water?

When glycerine mixes with water, it forms hydrogen bonding with water molecules. As both glycerine and water are polar solvents and it is known that like dissolves like, therefore, glycerine will dissolve into the water. Thus, it will form a miscible solution.

Is glycerin water or oil based?

Glycerin, also known as glycerol, is a natural compound derived from vegetable oils or animal fats. It’s a clear, colorless, odorless and syrupy liquid with a sweet taste.

What is the purpose of parenteral excipients in medicine?

Parenteral Excipients. Parenteral formulation excipients are used to enhance or maintain active ingredient solubility (solubilizers) and/or stability (buffers, antioxidants, chelating agents, cryo- and lyoprotectants).

How are solubilizers used in the formulation of drugs?

 SOLUBILIZERS  ANTI-OXIDANTS  CHELATING AGENTS  ANTI-MICROBIAL AGENTS  INERT GASES  BUFFERS  TONICITY CONTRIBUTORS  PROTECTANTS 5. SOLUBILIZERS AND CO-SOLVENCY  They are used to increase the soluability of the drugs which are slightly soluable in water. ex: Tweens Polysorbates

Why are anti-oxidants included in parenteral formulations?

ANTI-OXIDANTS  Anti-oxidants are included in parenteral formulations to slowdown or inhibit oxidative degradation of therapeutic agents.

What are the different types of parenteral formulations?

FORMULATION  Parenterals will be dispensed in several forms including solutions, suspensions, emulsions, Nano systems and powders (which are made in to injection by addition of solvent). I. Active ingredients II. Vehicles III.
