Ingredients Details
Hydrogenated Polyisobutene
Common Name(s): Polyisobutylene hydrogenated,pib,hpib
DESCRIPTION
What It Does: Provides viscous tacky-free emolliency with excellent adhesion for lip care and occlusive moisturisation.
Why It's Used: The lip care emollient standard — hydrogenated pib provides the ideal lip gloss and lip balm texture: high gloss, high adhesion, long-lasting, and tacky-free in a single hydrocarbon ingredient.
How It Works: Saturated branched polymer provides high viscosity without tackiness (unlike glycols). excellent adhesion to mucous membrane and skin from polymer chain entanglement. occlusive moisture barrier from dense hydrocarbon structure. mineral oil-like properties with higher molecular weight for longer retention.
Typically Found In: Lip gloss,lip balm,occlusive moisturisers,body products
TECHNICAL DETAILS
Primary Category: Functional ingredient – synthetic wax emollient
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–40%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – low; formulation-dependent
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
Hydrogenated pib's tacky-free high gloss is attributable to its narrow molecular weight distribution (vs natural waxes' broad distribution) providing uniform polymer chain length. uniform chain length creates ordered surface films that reflect light specularly (high gloss) while the branched polymer structure prevents the intermolecular attractions that cause tackiness in linear polymers.

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 – 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 – emollient
Secondary Functions: Cinnamic acid uv support,lupeol anti-inflammatory,rich emolliency
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–100%
SOURCING & ETHICS
Vegan Status: Yes – 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 – very low
Comedogenicity Rating: 0/5 – non-comedogenic (refined); 2/5 – 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.
