Hydroxypropyl guar is a chemical compound, a propylene glycol ether of guar gum.
Breakdown of the name and function of the components
- Hydroxypropyl - Indicates the presence of hydroxypropyl groups that have been added to the original molecule.
- Guar - Refers to guar gum, a polysaccharide extracted from the guar plant.
Description and function of the raw materials used in production
- Guar seeds - Provide the guar gum, which is the foundation for producing hydroxypropyl guar.
- Propylene oxide - Used to introduce the hydroxypropyl groups into the guar gum molecule.
Summary of its industrial synthesis process step by step
- Extraction - Guar gum is extracted from guar seeds through a milling process.
- Reaction - The extracted guar gum is then reacted with propylene oxide to introduce the hydroxypropyl groups.
- Purification - After the reaction, the product is purified to remove any impurities.
- Drying - The hydroxypropyl guar is then dried to remove any residual moisture.
What it is used for and where
Cosmetics
Binder agent. Ingredient that is used in cosmetic, food and pharmaceutical products as an anti-caking agent with the function of making the product in which it is incorporated silky, compact and homogenous. The binder, either natural such as mucilage, gums and starches or chemical, may be in the form of a powder or liquid.
Emulsion stabilizer. Emulsions are thermodynamically unstable. Emulsion stabilisers improve the formation and stability of single and double emulsions. It should be noted that in the structure-function relationship, molar mass plays an important role.
Film-forming agent. It produces a continuous ultra-thin film with an optimal balance of cohesion, adhesion and stickiness on the skin or hair to counteract or limit damage from external phenomena such as chemicals, UV rays and pollution.
Viscosity Enhancing Agent - aqueous. Since viscosity is important for increasing the chemical and physical stability of the product, Viscosity Enhancing Agent acqueous is an important dosage factor in gels, suspensions, emulsions, solutions. Increasing viscosity makes formulations less sedimentary and more homogeneously thickened.
