Earth Rhythm
Earth Rhythm Argan & Black Castor Oil Solid Conditioner Bar Tin, Balance Scalp pH
Earth Rhythm Solid Conditioner Bar with argan and black castor oil is an all-natural hair conditioning bar. Conditioner bars are less wasteful. Unlike most liquid conditioners that are made with around 60 to 80% water, these do not contain water and are full of the ingredients you want. This conditioner bar is infused with the goodness of argan oil which is full of fatty acids, mainly oleic acid and linoleic acid. Argan oil is also rich in vitamin E, which provides a fatty layer to your hair and scalp that help prevents dryness and can help reduce frizziness and also boost shine.

Ingredients Details
Argan Oil
Common Name(s): Argan oil,moroccan oil
CAS Number: 223747-87-3
DESCRIPTION
What It Does: Conditions and nourishes skin and hair with exceptional fatty acid, squalene, and tocopherol content.
Why It's Used: Premium multi-nutrient facial and hair oil โ its unique phytosterol and squalene composition provides anti-aging benefits beyond simple emolliency.
How It Works: Balanced oleic/linoleic acid ratio provides both emolliency and barrier repair. high squalene content (6-7%) provides antioxidant and sebum-compatible emolliency. tocopherols provide antioxidant stability and skin benefit. phytosterols inhibit 5-alpha-reductase and reduce inflammation.
Typically Found In: Premium facial oils,hair oils,anti-aging products
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Squalene content,phytosterol activity,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ100%
SOURCING & ETHICS
Vegan Status: Yes โ from argania spinosa kernels
Halal Status: Yes
Source Notes: Cold-pressed from roasted (food) or unroasted (cosmetic) argan kernels. unesco world heritage traditional production. fair trade certified sources available.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Argan oil's squalene content (6-7%) is among the highest of all plant oils, second only to olive oil. squalene is an endogenous skin lipid that declines with age, making argan oil's high squalene level particularly relevant for anti-aging facial use โ replenishing both essential fatty acids and age-depleting skin lipids simultaneously.

Quaternium-91
Common Name(s): Quaternium-91
DESCRIPTION
What It Does: Delivers targeted skin-conditioning or bioactive benefits through a specific mechanism of action suited to the formulation's intended purpose.
Why It's Used: Specialty actives address specific skin concerns through targeted molecular mechanisms, providing efficacy beyond what base formulation ingredients alone can achieve.
How It Works: The bioactive compound interacts with specific molecular targets in skin cells or the extracellular matrix โ enzymes, receptors, structural proteins, or signaling molecules โ triggering beneficial biological responses.
Typically Found In: Serums,treatments,moisturizers,specialty products
TECHNICAL DETAILS
Primary Category: Specialty actives
Secondary Functions: Skin-conditioning,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01โ5%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Specialty active ingredient; check individual sourcing for vegan status.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 0
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,peptides
Avoid Combining With: Incompatible with oxidizing agents; check ph stability
SCIENTIFIC NOTE
Specialty actives typically work through enzyme inhibition (e.g., tyrosinase inhibition for brightening, mmp inhibition for anti-aging), receptor activation (e.g., retinoid receptors, ppar-ฮณ for barrier genes), or transcription factor modulation (e.g., nrf2 for antioxidant gene upregulation). structure-activity relationships determine potency and selectivity.

Shea Butter
Common Name(s): Shea butter,karite butter
CAS Number: 91080-23-8
DESCRIPTION
What It Does: Provides deep nourishing emolliency with anti-inflammatory cinnamic acid esters and a uniquely rich unsaponifiable fraction.
Why It's Used: The most nutritious plant butter โ unique cinnamic acid esters, lupeol, and rich unsaponifiable fraction provide anti-inflammatory and wound healing benefits beyond standard fatty acid emolliency.
How It Works: Cinnamic acid esters absorb uv radiation providing mild natural uv filtering (spf 3-4). lupeol inhibits nf-kb for anti-inflammatory activity. high stearic acid provides occlusive barrier function. rich unsaponifiable fraction (4-9%) provides phytosterols, tocopherols, and triterpenes for bioactive skin benefits.
Typically Found In: Body butters,rich moisturizers,baby products,hair conditioners,lip balms
TECHNICAL DETAILS
Primary Category: Functional ingredient โ emollient
Secondary Functions: Cinnamic acid uv support,lupeol anti-inflammatory,rich emolliency
Application Areas:
Facial Skincare

Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ100%
SOURCING & ETHICS
Vegan Status: Yes โ from butyrospermum parkii nuts
Halal Status: Yes
Source Notes: Unrefined (raw) shea retains more unsaponifiable fraction and stronger natural scent/color. refined shea is odorless, white, and cleaner for formulation. certified fair trade supports west african women's cooperatives.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic (refined); 2/5 โ low (raw/unrefined)
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Shea butter's unsaponifiable fraction (4-9%, vs coconut oil's 0.5% and olive oil's 1-2%) is exceptionally rich in triterpenes, phytosterols, and tocopherols. this fraction is responsible for shea's anti-inflammatory and wound healing properties that simple fatty acid analysis fails to reveal.
