Arabinose is a five-carbon monosaccharide belonging to the pentose sugar family. L-Arabinose is the naturally occurring stereoisomer and is found in plant-derived materials such as gums, pectins and hemicelluloses. Because of its carbohydrate structure and multiple hydroxyl groups, Arabinose can interact readily with water and can be considered for specialized personal-care formulations.
As a cosmetic ingredient, Arabinose is relevant to formulations using sugar-derived and carbohydrate-based raw materials. Its small molecular structure and water compatibility make it suitable for formulation systems where a soluble carbohydrate ingredient is required.
For cosmetic raw-material sourcing, the stereochemical form is important. L-Arabinose, identified by CAS 5328-37-0, should not automatically be treated as interchangeable with other Arabinose stereoisomers.
L-Arabinose has the molecular formula C₅H₁₀O₅ and molecular weight 150.13 g/mol. Its CAS Number is 5328-37-0 and its EC Number is 226-214-6. Commercial analytical references describe L-(+)-Arabinose as a white powder or crystalline solid with high water solubility.
A current analytical reference reports ≥99% purity by GC, melting point of approximately 160–163°C, and optical rotation of approximately +103° to +105° under the stated conditions. These values are analytical/supplier-specific and should not automatically be presented as a universal cosmetic raw-material specification.
Arabinose provides a carbohydrate-based option for cosmetic formulations. Its hydroxyl-rich structure gives it strong affinity for water, which is relevant when developing water-containing personal-care products.
Unlike conventional high-use humectants such as glycerol or sorbitol, Arabinose is generally considered a more specialized sugar ingredient. Its role should therefore be determined according to the finished formulation rather than assuming a universal cosmetic function or concentration.
Arabinose may also be incorporated into formulations containing multiple carbohydrate-derived ingredients, allowing formulators to develop ingredient systems based on different sugar structures and physical properties.
Arabinose Cosmetic Ingredient can be evaluated for:
Its water solubility makes it particularly suitable for compatible aqueous formulations. The actual application level should be established through formulation development and stability testing.
Arabinose should be incorporated according to the requirements of the selected grade. Because L-Arabinose is highly water-compatible, it can be considered for the aqueous phase of suitable formulations.
The form and purity of the material should be established before formulation. Optical rotation can be particularly useful for confirming stereochemical identity, while chromatographic purity can help control related carbohydrate impurities.
A current analytical specification for L-Arabinose reports a pH range of approximately 5–7 at concentrations below 20%, while another analytical reference reports approximately pH 6.5–7.0 at 100 g/L. Because these measurements use different concentrations and specifications, they should not be merged into a single universal cosmetic pH limit.
Swapnroop supplies Arabinose Cosmetic Ingredient for manufacturers and formulators seeking specialized carbohydrate-based raw materials for personal-care applications. L-Arabinose can be considered for formulations where a water-soluble pentose ingredient is technically appropriate.
As a cosmetic ingredient manufacturer and bulk supplier in India, Swapnroop supports B2B sourcing requirements for cosmetic raw materials. The appropriate grade should be selected according to stereochemical identity, purity, physical characteristics and the approved technical specification.
