Carrageenan (iota type) is a natural thickening agent commonly used in skin care products. Gels made with Carrageenan are typically acid stable and can tolerate some sodium and magnesium salts. These gums are incompatible with calcium salts so are not suitable for mixing with milk or calcium rich extracts and minerals.
Origin: This product is naturally derived from Red Seaweeds of the family Solieriaceae
Appearance: Yellowish to white powder
Odour: Almost odourless
To Form A Gel: Carrageenan will swell in water. Heating that water decreases the time taken for the Carrageenan to fully swell but the gum will still eventually swell in cold water. We recommend using heat - 60-80C to ensure a fast and efficient gum hydration or a cold mix with a high shear mixer (i.e a mechanical mixer, not mixing by hand).
This gelling agent pairs well with Gum Arabic (Acacia Gum) and that combination is especially recommended if you wish to make a natural gel that has enhanced oil-stabilising properties.
Carrageenan Type: Iota - Great for soft, elastic gels (the other common cosmetic type is Lambda which won't gel but does thicken and can be used in cold process).
Benefits: It is a naturally derived thickening agent that imparts a soft, silky feel to skin and hair care products. The feel can turn a little slimy if you add too much so start with around 0.4% and see how that feels. A great thickener for serums as the extract its self is highly moisturising. This is also able to form crystal clear solutions.
Recommendations: Use up to 2%
Applications: Use as a thickening agent in creams and gels. This Carrageenan also has some suspending power so can be used in exfoliating gel cleansers.
Cautions: Acids can break down the structure of this thickener. Once gelled it is more acid stable.
