D-Mannose

D-Mannose at a glance

D-Mannose comes as granules or a fine powder that dissolves in water. It is a simple sugar, a close relative of glucose, and it occurs naturally in fruits such as cranberries, apples and peaches. The supplier specification lists skin care and personal care developments alongside uses outside cosmetics. In a cosmetic formula, mannose works as a humectant: it binds water and helps skin feel soft and comfortable. It is also a building block of many plant polysaccharides used in skin care. Confirm purity and grade on the supplier CoA and choose a cosmetic grade for skin care.

Sugars in skin care

Sugars have a long track record as gentle humectants. They are part of the skin's own water-binding system and show up in many moisturizing complexes. Mannose is a good choice when a brand wants a simple, recognizable ingredient with a clear natural origin. It dissolves quickly, keeps formulas clear and does not add a sticky feel at moderate levels.

Product formats

Toners and essences

Mannose dissolves completely and suits clear toners that should hydrate without leaving a film.

Serums

Combine it with hyaluronic acid and amino acids for a layered hydration serum.

Creams and lotions

Add it to the water phase of an emulsion as part of the humectant system.

Masks

Sheet mask essences and wash-off masks can use mannose for a soft, moist feel after use.

Personal care

Hand washes, body washes and shampoos can include a sugar humectant to soften the feel of cleansing.

Processing

Dissolve mannose in the water phase at room temperature or with mild warming. Stir until the solution is clear. Like other sugars it can brown with long heating, so add it to the cool-down stage if the formula is heated for a long time.

Good partners

The Natural Moisturizing Factor liquid shares the same hydration idea. Silk protein adds a smooth film to serums and hair care. More humectants are available in the actives catalog.

Testing

Measure skin hydration before and after use with a corneometer, or ask a panel to rate softness. Check the color of the product after storage in a warm cabinet, since sugars may darken over time.

Claims

Keep claims cosmetic: skin feels hydrated, soft and comfortable; with a fruit sugar.

Characteristics

Form: granules or fine powder. Solubility: in water. Type: simple sugar, a humectant in cosmetics. Card uses: skin care and personal care developments, among others outside cosmetics. Grade: supplier CoA.

Original recipe: sugar hydration toner, 100 g

Distilled water 90.40 g, D-mannose 3.00 g, glycerin 3.00 g, butylene glycol 2.00 g, sodium PCA 0.50 g, phenoxyethanol and ethylhexylglycerin 1.00 g, citric acid 0.10 g. Dissolve the mannose and sodium PCA in water, add the glycols and the preservative, check the pH and fill.

The fruit sugar story

Mannose gives a brand an easy origin story. It links to everyday fruits and to the sugars that plants use as building blocks. Pair it with fruit extracts for a consistent theme, such as a berry toner or an orchard-inspired body lotion, where every ingredient points back to the same fruit garden, and describe it as a gentle sugar humectant that keeps skin feeling soft.

Range ideas

A sugar toner, a hydrating sheet mask and a soft hand cream can share a simple humectant base built around mannose and glycerin. Each product then adds its own texture: water-thin for the toner, a soaked fabric for the mask and a light emulsion for the hands.

Lot records

Keep each CoA with the batch file and note the lot used.

Storage

Store closed in a dry place, because sugars pick up moisture from the air. Close the container after use.
