Rhamnose is a naturally occurring deoxy sugar belonging to the monosaccharide family. Unlike many common sugars, naturally occurring Rhamnose is predominantly found in the L-configuration. It occurs as a structural component of various plant polysaccharides and can be obtained from plant-derived carbohydrate materials.
As a cosmetic ingredient, Rhamnose is used in formulations where a sugar-derived ingredient with moisture-related and formulation-supporting properties is required. Its multiple hydroxyl groups contribute to its interaction with water, making it relevant to formulations designed around hydration and skin-conditioning concepts.
The INCI name RHAMNOSE is used for cosmetic ingredient declaration. Public cosmetic ingredient references identify Rhamnose with functions including humectant and fragrance-related functionality.
Rhamnose has the molecular formula C₆H₁₂O₅ and molecular weight 164.16 g/mol. Its primary CAS Number is 3615-41-6, while 10030-85-0 is also associated with Rhamnose in cosmetic ingredient references. The EC Number is 222-793-4.
Chemically, Rhamnose is also known as 6-deoxy-L-mannose. The absence of the hydroxyl group at the sixth carbon distinguishes Rhamnose from the corresponding hexose structure. Rhamnose can occur in different cyclic forms in solution, as is typical of monosaccharides.
Because cosmetic Rhamnose may be supplied in different grades and purities, the commercial specification should be established according to the actual raw material, manufacturing process and intended application.
Rhamnose can be incorporated into personal-care formulations as a humectant, where its hydroxyl-rich carbohydrate structure supports interaction with water. Humectant ingredients are commonly used in formulations intended to help maintain moisture within the formulation and contribute to the sensory characteristics of the finished product.
Cosmetic references also associate Rhamnose with fragrance-related functionality. However, its exact contribution in a finished formulation depends on concentration and the complete ingredient system.
Rhamnose is particularly relevant to formulations exploring carbohydrate-based cosmetic ingredients. It can be used alongside other sugar-derived ingredients such as Glucose, Fructose, Sucrose, Trehalose, Sorbitol and Mannitol, depending on the formulation objective.
Rhamnose Cosmetic Ingredient can be considered for:
Its water-compatible characteristics make it suitable for appropriate aqueous formulation systems. The actual application level should be established through formulation testing rather than assuming a universal use concentration.
Rhamnose is a small, polar carbohydrate and should be evaluated for compatibility with the aqueous phase and other formulation components. Factors such as concentration, pH, temperature, water content and storage conditions can influence the behaviour of sugar-based raw materials.
For high-purity Rhamnose, analytical controls such as identity, assay/purity, water content, residue on ignition and optical rotation may be relevant depending on the grade. However, there is no universal cosmetic raw-material specification that should be applied to every Rhamnose product.
Where a supplier-specific HPLC purity specification is used, the analytical method and acceptance criteria should be documented in the applicable COA. Numerical values should not be transferred from an analytical reagent specification to a cosmetic commercial specification without verification.
Swapnroop supplies Rhamnose Cosmetic Ingredient for manufacturers and formulators seeking specialized carbohydrate-based raw materials for personal-care applications. Rhamnose can be evaluated for moisture-focused, humectant and skin-conditioning formulation concepts.
As a cosmetic ingredient manufacturer and bulk supplier in India, Swapnroop supports B2B sourcing requirements for cosmetic raw materials. The appropriate Rhamnose grade should be selected according to purity, physical characteristics, application requirements and the approved product specification.
