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

DESCRIPTION

What It Does: Provides aromatic sensory benefit alongside bioactive skin activity from concentrated plant volatile compounds — including antimicrobial activity (tea tree, thyme, clove), anti-inflammatory activity (lavender, chamomile), or circulatory stimulation (peppermint, rosemary).

Why It's Used: Essential oils provide authentic 'aromatherapy' narrative with genuine bioactive chemistry — the concentrated terpenoid constituents have documented biological activity in addition to olfactory benefit, justifying ingredient claims beyond pure fragrance.

How It Works: Essential oil complexity: steam distillation concentrates volatile terpenes (monoterpenes, sesquiterpenes), phenylpropanoids, and other volatiles. antimicrobial activity from terpenoid membrane disruption (terpinen-4-ol, eugenol, thymol disrupt bacterial membranes); anti-inflammatory from sesquiterpene nf-kb inhibition; sensitisation risk from electrophilic monoterpene oxides and aldehydes.

Typically Found In: Aromatherapy,bioactive skin care,fragrance

DESCRIPTION

What It Does: Solubilizes fragrance oils and other lipophilic ingredients into water-based formulations.

Why It's Used: Standard fragrance solubilizer for water-based formulations – the industry standard for incorporating oil-soluble fragrances and actives into aqueous systems without separate oil phase.

How It Works: Hlb ~16.7 provides strong solubilization capacity for oils in water. laurate (c12) chain provides milder skin interaction than higher-hlb polysorbates. polyoxyethylene chains (20 eo units) provide high water solubility. effective solubilizer at 3-4:1 polysorbate:fragrance ratio.

Typically Found In: Toners,micellar waters,fragrance-containing aqueous products

TECHNICAL DETAILS

Primary Category: Functional ingredient – sorbitan ester emulsifier/solubilizer

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Typical Concentration Range: 0.5%–5%

SOURCING & ETHICS

Vegan Status: Conditional – sorbitol from plant, peg from petroleum

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: Same peg 1,4-dioxane concern as all peg compounds. quality-grade ps-20 should be tested for impurities.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Polysorbate 20's optimal solubilization ratio (3-4 parts ps-20 per part fragrance oil) is lower than expected from pure hlb theory. this efficiency arises from polysorbate's formation of very small, stable oil-in-water microemulsions (droplets <50nm) rather than conventional emulsions, providing optically clear, thermodynamically stable fragrance incorporation that conventional emulsifiers cannot achieve.

DESCRIPTION

What It Does: Provides mould and yeast focused broad-spectrum preservation in a widely accepted food-grade preservative.

Why It's Used: Standard mould and yeast preservative — potassium sorbate is effective at slightly higher ph than sodium benzoate, making it the preferred sorbate preservative for formulations at ph 4.5-6.

How It Works: Inactive salt form — sorbic acid (free acid, pka 4.76) is active. more effective than benzoate at higher ph (pka 4.76 vs benzoate 4.2). active at ph up to ~6.0 (meaningful sorbic acid present). inhibits malassezia and candida at lower concentrations than bacteria. synergistic with sodium benzoate.

Typically Found In: Cosmetics ph 4-6,natural preservation systems,combined with sodium benzoate

SAFETY & COMPATIBILITY

Safety Profile: Eu max 0.6% cosmetics. fda gras. synergistic with sodium benzoate. oxidises to sorbaldehyde (yellow colouration) on uv exposure — protect from light.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Potassium sorbate's antifungal mechanism (disruption of mitochondrial electron transport in fungi) is different from its antibacterial mechanism (cell membrane and enzyme disruption). this mechanistic bifunctionality provides broad spectrum from a single preservative, though the lower antifungal mic values mean mould and yeast protection is achieved at lower concentrations than bacterial protection.

DESCRIPTION

What It Does: Preserves acidic formulations against yeast and mold contamination.

Why It's Used: Natural-derived (from benzoic acid found in cranberries, cinnamon) preservative for acidic ph formulations where it provides excellent antimicrobial activity.

How It Works: Undissociated benzoic acid (active form, pka 4.2) penetrates microbial cell membranes and disrupts electron transport chain and ph homeostasis. at ph>5, mostly ionized (sodium salt) and inactive – requires acidic formulation ph for efficacy.

Typically Found In: Acidic serums,toners,low-ph formulations

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Eu max 0.5%. gras food additive. ewg score: 3 (benzene formation concern with vitamin c at >80°c – normal use temperatures do not form benzene).

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Sodium benzoate's strict ph dependency (90% inactive at ph>5.5) makes its preservative activity dramatically sensitive to formulation ph. a serum formulated at ph 4.0 is fully preserved by benzoate; the same formula adjusted to ph 5.5 has <10% of the preservative activity. this ph dependency must be considered in any benzoate-preserved formulation.
