Ingredients Details
Ceteareth-20
Common Name(s): Polyethylene glycol cetearyl ether,peg-20 cetearyl ether
CAS Number: 68439-49-6
DESCRIPTION
What It Does: Provides high-hlb o/w emulsification for stable cream formation from ethoxylated cetearyl alcohol.
Why It's Used: Classic self-emulsifying wax component for standard pharmaceutical and cosmetic cream formulation.
How It Works: 20 eo units on cetearyl alcohol chain provide hlb ~15-17 for strong o/w emulsification. often pre-blended with cetearyl alcohol as 'emulsifying wax' for simplified cream making. combined low-hlb cetearyl alcohol + high-hlb ceteareth-20 forms a balanced self-emulsifying system.
Typically Found In: Classic pharmaceutical and cosmetic creams
TECHNICAL DETAILS
Primary Category: Functional ingredient โ ethoxylated fatty alcohol emulsifier
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ8%
SOURCING & ETHICS
Vegan Status: Conditional โ peg petroleum; cetearyl vegetable
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
Ceteareth-20's combination with cetearyl alcohol in the classic 'emulsifying wax nf' creates what is called a 'mixed emulsifier system' where the fatty alcohol forms lamellar crystal phases that physically trap and stabilize oil droplets. this physical (lamellar crystal) + chemical (hlb balance) dual stabilization provides superior stability compared to either component alone.

Glycerin
Common Name(s): Glycerol,glycerine,1,2,3-propanetriol
CAS Number: 56-81-5
DESCRIPTION
What It Does: Glycerin pulls water from the environment and deeper skin layers into the outer skin layer (epidermis), boosting moisture levels and keeping skin soft, smooth, and plump.
Why It's Used: It is used in virtually every moisturizer, serum, and cleanser because it is highly effective at hydrating skin, is well-tolerated by all skin types, and enhances the texture and spreadability of formulations.
How It Works: As a humectant, glycerin forms hydrogen bonds with water molecules, trapping them in the skin. it also reinforces the skin barrier by integrating into lipid structures between skin cells.
Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners
TECHNICAL DETAILS
Primary Category: Humectant
Secondary Functions: Skin barrier support,emollient,solvent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ30% (typical: 3โ10%)
SOURCING & ETHICS
Vegan Status: Yes โ plant-derived (coconut, soy, palm) or synthetic
Halal Status: Yes โ when plant-derived or synthetic; verify source with supplier
Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low; non-irritating at all standard concentrations
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).
Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas
Avoid Combining With: No known incompatibilities at standard concentrations
SCIENTIFIC NOTE
Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.

Hydrolyzed Rice Protein
Common Name(s): Rice protein hydrolysate,oryza sativa protein
DESCRIPTION
What It Does: Provides vegan rice protein conditioning for hair strengthening and film formation.
Why It's Used: Leading vegan plant protein for hair conditioning formulations as an alternative to animal-derived hydrolyzed proteins.
How It Works: High glutelin and prolamin peptide content provides film-forming adsorption to hair surface. amino acid conditioning for hair and skin. lower cysteine than keratin hydrolysate but excellent vegan alternative. good substantivity via hydrogen bonding.
Typically Found In: Vegan hair conditioners,plant-based hair treatments
TECHNICAL DETAILS
Primary Category: Active ingredient โ plant protein
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ from oryza sativa (rice) protein
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
Rice protein's amino acid profile (high in glutamic acid and leucine) provides different conditioning character than wheat (glutamine-dominant) or silk (glycine/alanine-dominant) proteins. rice protein hydrolysate forms slightly less cohesive films than wheat protein but deposits more evenly across the hair fiber due to lower molecular weight distribution.

Limonene
Common Name(s): D-limonene,(r)-limonene,dipentene
CAS Number: 5989-27-5
DESCRIPTION
What It Does: Provides the defining fresh citrus fragrance note alongside solvent and antimicrobial properties.
Why It's Used: The citrus industry's primary fragrance compound and the most abundant terpene in essential oils โ limonene provides the clean, universally appealing fresh citrus scent character.
How It Works: D-limonene activates trpv1 mildly at high concentrations. antimicrobial via membrane disruption. solvent for oils and lipophilic compounds. cleaning via emulsification of lipid soils.
Typically Found In: Citrus-scented products,cleaning products,fragrance compounds
TECHNICAL DETAILS
Primary Category: Fragrance component โ cyclic monoterpene
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%โ3%
SOURCING & ETHICS
Vegan Status: Yes โ from citrus peel essential oils
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: Eu cosmetics regulation: declared fragrance allergen. oxidises to sensitising compounds (limonene hydroperoxides) on air exposure โ use with antioxidant stabilisers. ifra guidelines apply.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Limonene's sensitisation risk arises not from limonene itself but from its autooxidation products (limonene-1,2-epoxide and limonene hydroperoxides) formed on air exposure. fresh limonene has low sensitisation potential, but air-oxidised limonene's hydroperoxide products are potent skin sensitisers. this explains why oxidation-stabilised formulations (with bht or other antioxidants) are required to manage limonene safety.
