Ingredients Details
Cladosiphon Okamuranus Extract
Common Name(s): Cladosiphon okamuranus extract,cladosiphon okamuranus extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from polyphenol radical scavenging, anti-inflammatory activity from terpenoid nf-kb/cox pathway inhibition, and skin conditioning from the secondary metabolite complex.
Why It's Used: Cladosiphon okamuranus extract is selected for the characteristic secondary metabolite signature of cladosiphon okamuranus โ whether polyphenols, terpenoids, alkaloids, or polysaccharides, the phytochemical profile provides antioxidant, anti-inflammatory, or skin conditioning benefits specific to this botanical species.
How It Works: Polyphenol catechol h-atom donation for ros scavenging (rate constants 10โถ-10โน mโปยนsโปยน); terpenoids inhibit iฮบb kinase; flavonoids compete at cox-1/2; alkaloids modulate specific receptor targets.
Typically Found In: Botanical skin care

Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ10%

Lauryl Betaine
Common Name(s): Dodecyl betaine,c12 betaine,lauryl dimethyl betaine
CAS Number: 0683-10-3
DESCRIPTION
What It Does: Provides gentle foaming and antistatic conditioning with better hydrolytic stability than cocamidopropyl betaine.
Why It's Used: Stable betaine surfactant with improved hydrolytic stability and lower sensitisation potential vs capb for sensitive-positioned formulations.
How It Works: Direct c12 betaine without amide linkage โ hydrolytically more stable than capb's amide bond. zwitterionic character provides mildness and antistatic activity. lower residual dmapa (sensitiser in capb manufacture) than capb. milder foaming but better tolerability for sensitive skin.
Typically Found In: Sensitive skin cleansers,baby products,gentle shampoos
TECHNICAL DETAILS
Primary Category: Functional ingredient โ pure betaine surfactant
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 2%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ from coconut lauryl amine and chloroacetic acid
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.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Lauryl betaine's sensitisation advantage over capb arises from the manufacturing process: capb synthesis requires dimethylaminopropylamine (dmapa) which can remain as a trace impurity and is itself a sensitiser responsible for capb allergic contact dermatitis reports. lauryl betaine synthesis uses lauryl dimethylamine + chloroacetic acid without dmapa, eliminating this sensitiser impurity route.

Microcrystalline Cellulose
Common Name(s): Natural or modified biopolymer thickener,rheology modifier,film-former
CAS Number: N/a
DESCRIPTION
What It Does: Builds aqueous viscosity through polymer chain entanglement above the overlap concentration, forms conditioning films on skin and hair, and stabilises suspensions through yield stress.
Why It's Used: Natural biopolymer thickeners provide elegant formulation sensory without the tight ph requirements of synthetic carbomers โ preferred in shampoos and conditioners where broad ph tolerance and natural origin are both required.
How It Works: Polysaccharide chains above overlap concentration c* entangle forming a viscoelastic network โ viscosity scales as c^4.7 above c*, providing steep concentration-viscosity dependence. chemical modification (hydroxypropyl, hydroxyethyl) increases water solubility and cold-processability of otherwise difficult-to-dissolve natural polysaccharides.
Typically Found In: Shampoos,conditioners,gels
TECHNICAL DETAILS
Primary Category: Active ingredient โ cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ5%
SOURCING & ETHICS

Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Biopolymer thickeners are sensitive to electrolyte concentration โ high salt levels screen polymer charge interactions reducing viscosity. formulation salt content must be accounted for when selecting polymer concentration for target viscosity.

Oryza Sativa Rice Powder
Common Name(s): Oryza sativa rice powder extract
DESCRIPTION
What It Does: Provides antioxidant protection, soothing anti-inflammatory effects, and skin-conditioning benefits through plant-derived polyphenols and phytochemicals.
Why It's Used: Plant extracts concentrate bioactive phytochemicals evolved for environmental protection โ uv, microbial, and oxidative stressors โ that translate to skin benefits.
How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-ฮบb-mediated inflammatory signaling, scavenge reactive oxygen species through electron donation, and chelate pro-oxidant metal ions to reduce oxidative skin damage.
Typically Found In: Serums,toners,moisturizers,masks,essences
TECHNICAL DETAILS
Primary Category: Botanical extracts
Secondary Functions: Antioxidant,anti-inflammatory
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1โ10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Plant-derived extract; no animal components.
SKIN COMPATIBILITY
Irritancy Rating: 1899-12-31 00:00:00 -0800
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Niacinamide,hyaluronic acid,vitamin c,ceramides
Avoid Combining With: Strong oxidizing agents
SCIENTIFIC NOTE
Plant secondary metabolites (flavonoids, terpenes, phenolic acids) are biosynthesized as defense compounds against uv, herbivores, and pathogens. their anti-inflammatory activity typically derives from competitive inhibition of cox-2 and 5-lox enzymes (ic50 1โ50 ยตm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.
