Ingredients Details
Caprylic/capric Triglyceride
Common Name(s): Mct oil,fractionated coconut oil,c8/c10 triglyceride
CAS Number: 73398-61-5
DESCRIPTION
What It Does: Lightweight, stable emollient that solubilizes oil-soluble actives for excellent delivery without greasy feel.
Why It's Used: Universal lightweight emollient base and solubilizer for oil-soluble actives in serums and low-viscosity formulations where mineral oil or petrolatum would be too heavy.
How It Works: Medium-chain length provides ideal balance of spreading coefficient, penetration rate, and barrier-sealing properties. excellent solubilizer for vitamin e, retinoids, and other lipophilic actives.
Typically Found In: Serums,facial oils,sunscreens,anti-aging products,hair products
TECHNICAL DETAILS
Primary Category: Active ingredient – medium-chain triglyceride emollient
Secondary Functions: Active solubilizer,spreading agent
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%–50%
SOURCING & ETHICS
Vegan Status: Yes – from coconut/palm kernel oil
Halal Status: Yes
Source Notes: Fractionated by hydrolysis and re-esterification of coconut oil. only c8 and c10 fatty acids retained.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – very low; medium-chain length generally 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
Mct oil's medium-chain length (c8/c10) provides superior oxidative stability vs longer polyunsaturated chains and better skin aesthetics (lighter, less greasy) vs longer chain emollients (c16/c18). excellent solubilizer for retinoic acid, tocopheryl esters, and other lipophilic actives.

Pentylene Glycol
Common Name(s): 1,2-pentanediol,pentanediol,hydrolite-5
CAS Number: 5765-44-6
DESCRIPTION
What It Does: Provides humectant moisture retention with antimicrobial preservative-boosting activity.
Why It's Used: The balanced multifunctional diol — pentylene glycol provides the ideal balance of humectancy and antimicrobial activity for clean beauty preservation systems with excellent sensory compatibility.
How It Works: C5 diol: longer chain than propylene glycol providing better antimicrobial activity but shorter than 1,2-hexanediol (slightly lower membrane activity). two oh groups provide humectant water binding. solvent for fragrances and some actives. synergistic with phenoxyethanol reducing required phenoxyethanol concentration.
Typically Found In: Clean beauty products,natural preservation systems,moisturisers
TECHNICAL DETAILS
Primary Category: Functional ingredient – multifunctional pentanediol
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: 0.5%–3%
SOURCING & ETHICS
Vegan Status: Yes – synthetic
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – 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
Pentylene glycol's position in clean beauty preservation is due to a regulatory quirk: 1,2-pentanediol is not classified as a preservative in eu cosmetics regulations (unlike phenoxyethanol which requires preservative listing), so it can provide antimicrobial activity while not requiring the 'contains preservative' designation — enabling cleaner labels in natural-positioned formulations.

Phenoxyethanol
Common Name(s): 2-phenoxyethanol,rose ether,ethylene glycol monophenyl ether
CAS Number: 122-99-6
DESCRIPTION
What It Does: Prevents microbial contamination and spoilage in cosmetic formulations.
Why It's Used: The benchmark cosmetic preservative – eu-permitted up to 1%, effective against virtually all cosmetically relevant microorganisms, and excellent tolerability.
How It Works: Phenol ring provides broad antimicrobial activity via disruption of bacterial and fungal cell membranes and inhibition of enzymatic activity. effective against gram-positive and gram-negative bacteria, yeasts (candida), and molds (aspergillus). activity ph range: 3-9.
Typically Found In: All cosmetic formulations as primary preservative
TECHNICAL DETAILS
Primary Category: Functional ingredient – broad-spectrum preservative
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%–1% (eu max 1%)
SOURCING & ETHICS
Vegan Status: Yes – synthetic
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Eu cosmetics regulation max 1%. sccs assessed as safe at ≤1%. avoid use around eyes in baby products per some country regulations. ewg score: 4.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Phenoxyethanol's widespread adoption as the primary cosmetic preservative followed the phaseout of parabens from many formulations in the 2000s-2010s. despite having a comparable or better safety profile to parabens, it is often cited in 'free-from' formulations – a consumer perception issue rather than a scientific safety concern.
