A multi-humectant hydration concentrate self-preserved through water activity reduction. Five humectants — Ectoin, Sodium Hyaluronate, Trehalose, Betaine, and Glycerin — layered to deliver hydration across every skin depth, from cellular osmoprotection to stratum corneum moisture retention. No preservatives. No PEGs. One drop-in solution for clean-label hydration claims.

Self-preservation achieved via water activity reduction (Aw ≤0.83) — no preservative system required. Batch CoA and humectant quantification available in TDS.
Ectoin forms a structured hydration shell around proteins and cell membranes, protecting against UV, pollution, and thermal stress. Cellular-level defense paired with surface hydration in a single ingredient.
Sodium Hyaluronate — high-molecular-weight hyaluronic acid — binds water at the dermal-epidermal junction. Delivers immediate and long-lasting plumping while reinforcing the skin's native water reservoir.
Trehalose stabilises membrane proteins under desiccation stress. Proven barrier protection in water-stressed skin states — essential for climate-exposed and post-treatment formulations.
Osmolyte with compatible-solute activity. Soothes and stabilises skin under environmental or formulation stress. Well-tolerated in sensitive-skin protocols.
Water activity reduction below Aw 0.83 makes the matrix microbiologically hostile — no parabens, no phenoxyethanol, no formaldehyde-releasers required. Supports the strictest clean-label briefs.
Water-compatible, pH-stable between 4.5 and 5.0, and incorporates directly into the aqueous phase. Broad compatibility with serums, emulsions, gels, and essences.
A compatible solute that structures water around cell membranes and proteins. Protects intracellular contents against osmotic, UV, and oxidative stress. The deepest layer of the stack.
Binds up to 1000× its weight in water. Reinforces the native hyaluronic reservoir in the dermis, delivering sustained volume and plumping.
Non-reducing disaccharide that stabilises membranes and proteins against water loss. The layer that keeps hydration intact during environmental stress.
A natural osmolyte that soothes and regulates intracellular water balance. Adds anti-irritancy and smooths sensory profile.
Classical humectants forming the stratum-corneum-facing layer. Draw atmospheric moisture and extend hydration duration at the skin surface.
| Parameter | Specification |
