Reusable seaweed jelly patches for deep hydration and enhanced active delivery

Reusable Seaweed Jelly Patches can be used alone or layered over High Tide Serum or Low Ebb Lotion to create a deeply hydrating environment and enhance the delivery of applied actives. Thickened with red seaweed-derived carrageenan, the patches provide a soothing and restorative skincare experience.
 

Key Benefits:

        



Formulation Expertise:

Premix Gelcarin PC 812 and Gelcarin PC 379 in humectants (e.g. glycerin, PO 070 etc) to fully wet them out before adding to water. This reduces the risk of clumping, but the premix will still need to be added to the water slowly under fast agitation or homogenisation.

Beaute by Roquette PO 070 is used as the main humectant as sorbitol binds more water than other polyols, giving better water holding stability to these jelly patches.

N.A.S Gardenia 2168 is an oil soluble colour so this needs to be premixed into an oil-based ingredient to ensure no clumping and full colour development.

This formulation needs to be poured into moulds very hot, approximately 75°C, as it will begin setting very quickly.
 
Gelcarin PC 812/379

Gelcarin PC812 and PC379 are natural polymers extracted from sustainably sourced red seaweed. PC812 has a high gel potential due to its Kappa structure making it ideal for creating hard, brittle gels. PC379 is an Iota-carrageenan that yields highly elastic, thixotropic, freeze-thaw stable gels ideal for cosmetic creams and lotions. By combining both carrageenan types, we can create a variety of textures, including sticks and jellies.

Beauté By Roquette ST 720

Innovative, plant-based, water-soluble film-forming agent, ideal for advanced hair care and skincare formulations. Derived from pea starch, it creates a flexible, smooth, and continuous barrier over the skin, effectively shielding it from atmospheric pollutants while maintaining a non-occlusive feel.
 
Hydroxypropyl Starch
 
Dekamulen Power Feel

Natural derived cellulose-based emulsifier offering an amazing feel - silky, non-sticky, without a peeling effect. Dekamulen Power’Feel is the natural sourced solution to formulate all kinds of emulsions, especially light and fluid textures, e.g. face serums and creams, BB creams, deodorants, etc. Low use levels (1 - 1.5 %). Cold process possible, very easy to use.
 
Microcrystalline Cellulose, Xanthan Gum, Cellulose Gum
 
Gransense Hydro -18X/C

A versatile ingredient ideal for skincare formulations, providing a luxurious, smooth feel and enhancing product application. It easily blends into water-based systems and works in both hot and cold processes. Compatible with a wide range of oils, it supports diverse textures and finishes, making it perfect for high-performance creams, lotions, and other skincare products.

Hydrintense

Derived from unicellular red microalgae, Hydrintense gives long lasting hydration to the skin due to the secretion of a water trapping exopolysaccharide. A film is formed on the skins surface, bringing water into the skin, reducing TEWL and improving the skin’s microrelief.

Amitose R-PD

Amitose R-PD is an amino acid derivative combining moisturising glycerin with strongly adsorbing arginine. It binds firmly to skin and damaged hair through hydrogen and ionic bonding, making it difficult to rinse off. Its low molecular weight also allows penetration into the hair, providing long-lasting moisturisation.

Process
  1. Add Beauté by Roquette® ST720 to water while stirring and heat to 75°C.
  2. Premix Phase B and slowly add it to Phase A under high agitation to prevent lump formation. Continue mixing until fully dispersed and homogeneous.
  3. Add Phase C ingredients one by one, ensuring each ingredient is fully dispersed before adding the next.
  4. Premix Phase D and heat to 75°C until fully dissolved. Add to the main batch and stir until homogeneous.
  5. Add Phase E ingredients one by one, ensuring the batch remains homogeneous after each addition. Homogenise the batch using a Silverson (4000 rpm, 2 minutes)
    Immediately pour the product into the moulds and leave to cool completely before removing patches from the moulds.
