IO Marine Polysaccharide Active Liquid

Algae are rich in complex sugars that help them survive changing tides, salt and sun.

Product data

Liquid, water-soluble. Applications from the card: creams, lotions, serums and balms. For this ingredient, the supplier CoA of each lot confirms the exact INCI, composition and recommended level.

Marine saccharides in skin care

Saccharides from algae are used for moisture, film-forming and comfort. They suit brands with a marine or natural story. Keep the source claim tied to the INCI on the CoA.

Product formats

Calming serum

A light serum for sensitive-feeling skin.

Comfort cream

A daily cream for reactive-feeling skin.

Body lotion

A gentle lotion after the shower.

Balm

A richer balm for dry areas.

Formulating guidance

Add the active during cool-down into the water phase. Pair it with bisabolol for a calm-looking story, D-Panthenol for comfort and ceramide NP for a barrier message. More ingredients are listed under actives.

Claims

Use cosmetic wording such as calm-looking, comfortable, less reactive-feeling skin. Support numbers with panel tests and redness-look measurements on the finished product.

Who the products are for

Customers with sensitive-feeling skin, those whose skin feels tight after cleansing and people who react to fragrance.

Sensitive-skin design

Keep the ingredient list short, skip fragrance and essential oils, use mild preservatives and test on sensitive panelists.

Sensory design

Comfort products should feel soft and cushiony. Balance humectants with light emollients.

Testing

Run stability at room temperature and 40 °C, checking pH, viscosity, color and odor.

Packaging

Airless pumps keep sensitive-skin products clean and protected.

Batch quality

Keep the CoA for each lot and store retained samples.

Range planning

A serum, a cream and a body lotion form a gentle, fragrance-free line.

Why sensitive skin needs comfort

Sensitive-feeling skin reacts to wind, cold, hot water, fragrance and even some textures with tightness, stinging or a flushed look. Comfort products aim to make skin feel soft and calm and to support its barrier with gentle ingredients. Customers in this group read labels carefully, so a short, clear ingredient list builds trust.

Marine positioning

If the CoA confirms algal origin, a soft marine theme works well: clean blue packaging, fragrance-free products and a calm message. Keep claims factual and avoid suggesting any health benefit.

Seasonal use

Winter is the peak season for reactive-feeling skin. A richer balm for cold months and a lighter serum for summer can share the active.

Preservation

Use mild preservatives suitable for sensitive skin and confirm with a challenge test.

Body care

A gentle body lotion with the active suits customers whose legs and arms feel tight after showering, especially in winter.

Record the lot number in your batch log so every production run can be traced back to its certificate of analysis. Retain a small sample of each lot for at least the shelf life of the finished product, since it makes later quality questions much easier to answer.

Storage

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