Mannose is a naturally occurring six-carbon monosaccharide belonging to the hexose carbohydrate family. It is structurally related to glucose and is found in various plant-derived materials, particularly as a component of mannans and other carbohydrate structures. As a specialized cosmetic ingredient, Mannose can be considered for formulations requiring a water-soluble carbohydrate with moisture-related functionality.
Mannose has several hydroxyl groups that contribute to its strong interaction with water. This characteristic makes it relevant to cosmetic formulation systems where moisture management and humectant functionality are desired. The cosmetic INCI name is MANNose, referring to D-mannose as the ingredient identity.
D-Mannose has the molecular formula C₆H₁₂O₆ and molecular weight 180.16 g/mol. Its primary CAS Number is 3458-28-4 and its EC Number is 222-392-4. D-Mannose can exist in linear and cyclic forms in solution, with the cyclic pyranose form being an important structural representation.
Commercial analytical grades demonstrate that Mannose can be supplied at high purity. For example, current analytical specifications report purity of >98.0% by HPLC, while another specification reports assay ≥98.5%, water content ≤0.5%, and optical rotation of approximately +14.0° ± 0.5° under defined conditions. These are product-specific analytical specifications and should not automatically be treated as universal cosmetic requirements.
Mannose is recognized in cosmetic ingredient inventories as a humectant, meaning it can contribute to the retention of moisture within cosmetic formulations.
Its carbohydrate structure makes it a useful specialized ingredient for formulation development where sugar-based raw materials are desired. Mannose can be evaluated alongside other carbohydrate ingredients such as Glucose, Fructose, Sorbitol, Mannitol, Trehalose and Raffinose.
The practical effect of Mannose depends on concentration, formulation composition, pH, water content and the other ingredients present. It should therefore be described as a formulation ingredient rather than making unsupported claims about treating particular skin conditions.
Mannose Cosmetic Ingredient can be considered for:
Its water-compatible characteristics make it suitable for compatible aqueous formulations. The actual use level should be established through formulation development, compatibility testing and stability evaluation.
Mannose is a highly polar carbohydrate and can be incorporated into suitable water-based formulation systems. Formulators should consider dissolution conditions, concentration, pH, processing temperature and storage conditions when incorporating the ingredient.
Optical rotation can be useful as an identity and stereochemical quality parameter. This is particularly relevant because Mannose belongs to a family of stereochemically related sugars, and the specified form should be clearly established in the raw-material documentation.
For high-purity Mannose, chromatographic assay, water content, optical rotation, identification and inorganic residue can be useful quality-control parameters. However, values from analytical reagent specifications should not automatically be transferred to an SDP cosmetic-grade COA.
Swapnroop supplies Mannose Cosmetic Ingredient for manufacturers and formulators seeking specialized carbohydrate-based raw materials for personal-care applications. Mannose can be evaluated for moisture-focused and humectant-oriented formulation systems where its technical properties are appropriate.
As a cosmetic ingredient manufacturer and bulk supplier in India, Swapnroop supports B2B sourcing requirements for cosmetic raw materials. The appropriate Mannose grade should be selected according to purity, physical characteristics, analytical method and intended formulation.
