Why This Works for Your Specific Profile

Damage Index:

Healthy to moderately damaged hair experiences over-conditioning or protein overload causing limpness or rigidity

Water Quality:

Fine hair becomes weighed down and greasy from heavy formulation

Hair:

Closed cuticles resist product penetration causing surface buildup without internal benefits

Active Lifestyle:

Activity levels outside optimal range affect product performance and maintenance requirements

Ingredients Details

Algin

Common Name(s): Algin,cosmetic active,functional ingredient

CAS Number: N/a

DESCRIPTION

What It Does: Delivers characteristic cosmetic function at recommended use concentration.

Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.

How It Works: Works through the mechanism of its molecular class โ€” physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.

Typically Found In: Skin care formulations

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%โ€“10%

SOURCING & ETHICS

Vegan Status: Conditional

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: 1โ€“2.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Algin has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Carrageenan

Common Name(s): Irish moss extract,chondrus crispus extract,kappa/iota/lambda carrageenan

DESCRIPTION

What It Does: Provides natural marine seaweed gellation and thickening with moisturizing sulfated polysaccharide conditioning.

Why It's Used: Marine natural thickener and gellant for seaweed-inspired formulations with moisturizing sulfated polysaccharide activity.

How It Works: Sulfated galactan helical coils form ionic junction zones with potassium (kappa), calcium (iota), or none (lambda) providing different gel textures. iota-carrageenan forms elastic, non-syneretic gels preferred for cosmetics. sulfate groups provide ha-like moisture retention.

Typically Found In: Natural gels,marine skincare,moisturizing masks

TECHNICAL DETAILS

Primary Category: Functional ingredient โ€“ seaweed polysaccharide gellant

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%โ€“2%

SOURCING & ETHICS

Vegan Status: Yes โ€“ from red seaweed

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

Iota-carrageenan's gel mechanism requires calcium ion cross-linking (vs kappa-carrageenan's potassium requirement). this calcium dependency means iota carrageenan gels are skin-compatible (skin's natural calcium levels provide gel-triggering) and provides a unique 'skin-responsive gellation' where the natural calcium in sweat and skin surface triggers in-situ gel formation on application.

Chitosan

Common Name(s): Chitosan,deacetylated chitin biopolymer,cationic film-former

CAS Number: N/a

DESCRIPTION

What It Does: Forms a substantive cationic film on skin and hair through electrostatic attraction to negative surfaces, provides antimicrobial activity against gram-positive bacteria and fungi, and promotes wound healing via keratinocyte and fibroblast stimulation.

Why It's Used: The only natural cationic biopolymer from shellfish providing simultaneous substantive deposition and antimicrobial activity โ€” preferred over synthetic quats for clean-label hair and skin conditioning.

How It Works: Protonated amine groups (pka ~6.5) in chitosan electrostatically bind hair cuticle and skin corneocytes (net negative charge at ph >5.5), depositing a film that reduces friction and provides conditioning. cationic character disrupts bacterial membranes providing antimicrobial activity.

Typically Found In: Hair conditioning,wound care,film-forming

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%โ€“3%

SOURCING & ETHICS

Vegan Status: No โ€“ shellfish

Halal Status: Conditional

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: 1โ€“2.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Chitosan's partial structural identity with hyaluronic acid (shared n-acetylglucosamine backbone) provides biocompatibility with skin extracellular matrix proteins and partial cross-reactivity with cd44 hyaluronan receptors.

Coco-glucoside

Common Name(s): Coconut glucoside,apg c8-c16

CAS Number: 68515-73-1

DESCRIPTION

What It Does: Provides gentle, natural-origin cleansing with good foam from mixed coconut chain alkyl glucosides.

Why It's Used: Widely used natural surfactant for green beauty formulations requiring good foam performance with natural-origin and mild credentials.

How It Works: Mixed c8-c16 fatty alcohol chain lengths from coconut provide broader foam stability than single-chain glucosides. non-ionic glucoside headgroup provides mildness. better detergency and rinsing than individual chain-length apgs due to mixed chain distribution.

Typically Found In: Natural shampoos,body washes,facial cleansers

TECHNICAL DETAILS

Primary Category: Functional ingredient โ€“ coconut alkyl glucoside

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 2%โ€“20%

SOURCING & ETHICS

Vegan Status: Yes โ€“ from coconut fatty alcohols and glucose

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: 1โ€“2.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Coco-glucoside's natural chain length distribution (c8-c16) provides synergistic surfactant effects where different chain lengths optimize different properties: shorter chains provide initial foam burst, longer chains provide foam stability and soil removal, creating better overall performance than any single chain length alone.
