C15-35 isoparaffin/isoalkylcycloalkanes is a chemical compound, branched chain of hydrocarbons, obtained from crude oil by various chemical processes including hydrodeoxygenation-hydroisomerisation a catalytic process that converts normal paraffin into isoparaffin. The numbers refer to the carbon atoms in the alkyl chain.
The name describes the structure of the molecule:
- "C15-35" indicates the range of carbon chain lengths present in the molecule, ranging from 15 to 35 carbon atoms.
- "Isoparaffin" refers to branched paraffins, which are saturated hydrocarbons with branched structures.
- "Isoalkylcycloalkanes" are cyclic compounds with a branched alkyl chain attached to the cycle.
Raw materials used in production.
Crude oil, specific catalysts for hydroisomerization (such as platinum on alumina support), hydrogen, and impurities such as sulfur, nitrogen, and oxygen.
Step-by-step summary of industrial chemical synthesis process.
- Extraction. Isoalkanes are derived from crude oil.
- Refining. The crude oil undergoes distillation to separate the different fractions at various boiling points.
- Hydrotreating. Before hydroisomerization, the paraffinic fraction undergoes hydrotreating to remove impurities like sulfur, nitrogen, and oxygen. This process occurs in the presence of a hydrotreating catalyst and hydrogen.
- Hydroisomerization. The paraffinic fraction is then exposed to catalysts such as platinum on alumina support, under specific temperature and pressure conditions in the presence of hydrogen. The normal paraffins convert to isoparaffins.
- Separation. Post-conversion, the products undergo separation processes like fractional distillation. The isoalkanes of specific carbon chain lengths (C15-C35) are separated from others.
What it is used for and where
Cosmetics
Skin conditioning agent - Miscellaneous. This ingredient has the task of modifying the condition of the skin when it is damaged or dry by reducing its flakiness and restoring its elasticity.
Cosmetics and Personal Care. C15-35 Isoparaffins can be found in cosmetic and personal care formulations, especially in skin creams, lotions, foundations, hair sprays, and other cosmetic preparations. They serve multiple purposes.
Emollient. Gives a soft, smooth feel to the skin.
Texture Enhancer. Improves the texture and spreadability of formulations.
Solvent. Helps dissolve or disperse other ingredients in the formulation.
Commercial applications
Industrial Applications. Isoparaffins, in general, are used in a variety of industrial applications because of their solvent properties. They can be found in paints, coatings, cleaning agents, and more.
Lubricants. They might be used in lubricant formulations due to their oil-like properties.
