Laminaria Ochroleuca Extract, Polyquaternium-51, Daucus Carota Sativa (Carrot) Root Extract, Ectoin
Ingredients Details
Ectoin
Common Name(s): Ectoin,extremophile stress protector,anti-aging humectant
CAS Number: N/a
DESCRIPTION
What It Does: Hydrates by forming a water-shell around skin biomolecules, stabilises cellular membranes against heat/uv stress, and reduces inflammatory cytokine release in stressed skin.
Why It's Used: Provides dual humectancy plus cellular protection โ unique among humectants for its documented ability to stabilise skin proteins and membranes against uv and environmental stress, not just attract water.
How It Works: Ectoin's tetrahydropyrimidine ring forms an ordered hydration shell around proteins, lipid bilayers, and dna through kosmotropic water structuring. this preferential hydration excludes denaturants and uv-stress mediators from biomolecule surfaces while simultaneously providing humectant moisture binding.
Typically Found In: Sensitive skin,uv protection actives,anti-inflammatory
TECHNICAL DETAILS
Primary Category: Functional ingredient โ humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ2%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Extremophile bacteria accumulate ectoin at up to 15% intracellular concentration to survive 100ยฐc temperatures and extreme salinity โ the same biomolecule protection mechanism applies to human skin cells at cosmetic concentrations.

Polyquaternium-51
Common Name(s): Polyquaternium-51,cationic conditioning polymer,substantive film-former
CAS Number: N/a
DESCRIPTION
What It Does: Deposits a conditioning film on hair and skin through electrostatic attraction to negative cuticle/corneocyte surfaces, reduces hair-on-hair friction for improved combability and detangling, eliminates static charge buildup, and provides anti-frizz humidity resistance.
Why It's Used: Cationic polymers are the primary hair conditioning technology โ the permanent positive quaternary ammonium groups provide substantive deposition that resists rinsing, delivering persistent conditioning between washes unlike small-molecule cationic conditioners.
How It Works: At shampoo/conditioner ph 4.5โ5.5, hair cuticle carries net negative charge (isoelectric point ph ~3.5). polyquaternium cations undergo electrostatic attraction depositing on the cuticle surface. during rinsing, the deposited polymer film persists from reduced surface-solution equilibrium at low bulk concentration โ substantive deposition from favourable interfacial versus bulk partitioning.
Typically Found In: Shampoos,conditioners,leave-in products
TECHNICAL DETAILS

Secondary Functions: Skin conditioning

Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ3%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.

SCIENTIFIC NOTE
Different polyquaternium numbers indicate different backbone chemistries: pq-7 (acrylamide/quaternary acrylate copolymer) for leave-on flexibility; pq-10 (hydroxyethylcellulose/quaternary ammonium) for substantive deposition; pq-11 (vp/dimethylaminoethyl methacrylate) for styling fixation.
