Butylene Glycol
Common Name(s): 1,3-butanediol,bg,1,3-butylene glycol
CAS Number: 107-88-0
DESCRIPTION
What It Does: Provides humectant hydration and active ingredient solubilization with excellent skin feel.
Why It's Used: Preferred glycol humectant in premium and k-beauty formulations for superior skin feel vs propylene glycol with equivalent functionality.
How It Works: Two hydroxyl groups at 1,3-positions provide water binding and solvent activity. better tolerated than propylene glycol with minimal sensitization risk. 4-carbon backbone provides slightly greater hydrophobic character enabling dissolution of less polar actives vs pg.
Typically Found In: Toners,essences,serums,k-beauty formulas
TECHNICAL DETAILS
Primary Category: Functional ingredient โ glycol humectant
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: 1%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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
K-beauty's preference for butylene glycol over propylene glycol is driven by two factors: bg's superior skin feel (less tacky than pg's higher viscosity) and its lower sensitization potential (1,3-bg has better spatial distribution of hydroxyl groups that reduces protein interaction vs pg's 1,2-position oh groups).

Chamaecyparis Obtusa Leaf Extract
Common Name(s): Chamaecyparis obtusa leaf extract,chamaecyparis obtusa leaf 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: Chamaecyparis obtusa leaf extract is selected for the characteristic secondary metabolite signature of chamaecyparis obtusa 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
