Polysaccharide gel

About polysaccharide gel

Polysaccharide gel is a viscous gel that dissolves in water and glycerin. The supplier specification lists a near-neutral pH for the material. Polysaccharides are sugar-based molecules, and many of them hold water well and form a soft film on the skin surface. That gives products a smooth, cushiony feel and a hydrated finish. The supplier CoA confirms the INCI and level for each lot.

Texture as a selling point

Shoppers judge skin care by feel as much as by results. A serum that glides on and leaves a soft, hydrated film feels luxurious. Polysaccharide gel helps formulators reach that feel, and it can also replace part of the thickener in light products.

Product formats

Serums

The gel gives serums a cushiony glide and a hydrated finish. Combine it with hyaluronic acid for a classic hydration serum.

Gel creams

In gel creams, it adds body and a smooth feel, especially with a small oil phase.

Masks

Gel masks and sleeping masks use it for a soft, comfortable layer.

Eye gels

Eye gels benefit from the smooth film and a light, cooling feel.

Processing

Because the gel is viscous, weigh it carefully and disperse it in part of the water or in glycerin first. Stir until smooth before adding other ingredients. Add it during cool-down unless the CoA says otherwise.

Partners

Hyaluronic acid, glycerin and Instant lifting Complex suit tightening-feel serums. IO Hydration Serum Active Liquid adds a hydration active. Texture helpers and hydrators are grouped in our actives catalog.

Formulating tips

Some polysaccharides react to salts and low pH by thinning. Test the final viscosity after adding acids or salt-containing actives. Balance the gel with other humectants to avoid a tacky feel.

Testing

A panel can rate glide, tackiness and softness. Check viscosity after warm and cold stability tests.

Claims

Use texture and feel wording: a cushiony, silky texture; skin that feels smooth, soft and hydrated.

Layering

Products with polysaccharide gel layer well under creams and makeup if the level is balanced. Test with common moisturizers and foundations and note any pilling.

Sensory design

Pair the gel with a light fragrance or none, and with clear or frosted packaging that shows the smooth texture.

Characteristics

Form: viscous gel. Solubility: water, glycerin. PH of material: near-neutral. Roles: hydration, smooth film, texture. Typical products: serums, gel creams, masks, eye gels. INCI and level: supplier CoA.

Original recipe: cushion hydration serum, 100 g

Distilled water 81.40 g, glycerin 4.00 g, polysaccharide gel 6.00 g, sodium hyaluronate 0.30 g, IO Hydration Serum Active Liquid 3.00 g, panthenol 1.50 g, betaine 2.00 g, preservative 1.00 g, citric acid solution to target pH 0.80 g. Disperse the gel and hyaluronate in glycerin, add water, then the rest below 40 °C.

Replacing part of the thickener

In light serums, the gel can replace part of a gum or carbomer. This gives a softer, less jelly-like texture and a more cushiony feel. Start by swapping a quarter of the thickener for the gel and compare viscosity and feel. Keep careful notes, since small changes in the thickener system can change how the product dispenses from a pump or dropper. Test the final product in its real package before launch, and check how it behaves at warm and cold temperatures too.

Eye area

For eye gels, keep the formula simple and test comfort around the eyes with a small panel.

Packaging

Viscous gel products dispense well from airless pumps, which also protect the formula from air and contamination.

Storage

Store closed in a cool place away from light. Close the container after use.
