Aroma Care Essentials Apricot Face Scrub

DESCRIPTION

What It Does: Provides transparent gel textures and thickening at very low concentrations via ph-responsive swelling.

Why It's Used: The most widely used gel thickener – provides crystal-clear, stable gels at concentrations as low as 0.1-0.5% with ph-controlled viscosity.

How It Works: Highly crosslinked polyacrylic acid remains tightly coiled at acidic ph. neutralization with naoh or triethanolamine ionizes carboxylic groups causing electrostatic repulsion that unfolds and swells the polymer coils, dramatically increasing viscosity. concentration-dependent thickening.

Typically Found In: Gels,serums,emulsions,sunscreens

SCIENTIFIC NOTE

Carbomer's ph-responsive swelling mechanism provides an elegant formulation control tool: a neutralized gel can be liquefied by ph reduction (adding acid) and re-thickened by reneutralization. this reversible rheology control allows two-phase products that mix on application without the need for mechanical emulsification.

DESCRIPTION

What It Does: Attracts and retains moisture in the sc, improves skin barrier function at low concentrations, provides gentle keratolytic softening, and acts as a co-solvent for water-soluble actives.

Why It's Used: The reference humectant — lowest cost, best safety profile, universal formulation compatibility, and present naturally in the sc via lipase-mediated glycerolipid hydrolysis makes glycerin the industry standard against which all humectants are benchmarked.

How It Works: Three hydroxyl groups form 6 h-bonds with water molecules per glycerol unit — the highest oh-group density per carbon of any commercial humectant. glycerin also down-regulates epidermal serine proteases that overactivate in dry sc, improving desquamation and barrier integrity.

SCIENTIFIC NOTE

Epidermal lipases hydrolyse sc glycerophospholipids during cornification, releasing glycerol that contributes to the natural nmf — topical glycerin directly supplements this endogenous sc humectant pool.

DESCRIPTION

What It Does: Provides highly potent broad-spectrum preservation at very low concentrations in rinse-off formulations.

Why It's Used: Most potent cosmetic preservative — mit provides effective preservation at concentrations 10-100× lower than most other preservatives, enabling clean-label preservation at minimal ingredient load.

How It Works: Electrophilic isothiazolinone ring reacts with bacterial thiol enzymes (glutathione, coa-dependent enzymes) via michael addition for rapid kill. very potent — mic vs e. coli 0.06μg/ml (vs phenoxyethanol mic ~400μg/ml — 6000× more potent). rapidly biodegradable.

SAFETY & COMPATIBILITY

Safety Profile: Eu regulation 2014/1298: mit banned from leave-on products. max 15ppm in rinse-off only. contact sensitiser — causes occupational dermatitis epidemic in hairdressers and consumers. sccs noted no safe level for leave-on. 2016 eu restriction driven by major sensitisation epidemic.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Mit's sensitisation epidemic (2010-2015) is one of the most significant cosmetic safety events in modern dermatology: a dramatic increase in contact allergy patch test positive rates from <1% (2005) to 7% (2015) in the eu was directly traceable to the widespread introduction of mit in leave-on products. this epidemic prompted the fastest eu cosmetic regulatory action in history and demonstrates the critical importance of patch test surveillance in monitoring emerging cosmetic allergens.

DESCRIPTION

What It Does: Deposits a conditioning film on hair and skin through electrostatic attraction to negative cuticle/corneocyte surfaces, reduces hair-on-hair friction for improved combability and detangling, eliminates static charge buildup, and provides anti-frizz humidity resistance.

Why It's Used: Cationic polymers are the primary hair conditioning technology — the permanent positive quaternary ammonium groups provide substantive deposition that resists rinsing, delivering persistent conditioning between washes unlike small-molecule cationic conditioners.

How It Works: At shampoo/conditioner ph 4.5–5.5, hair cuticle carries net negative charge (isoelectric point ph ~3.5). polyquaternium cations undergo electrostatic attraction depositing on the cuticle surface. during rinsing, the deposited polymer film persists from reduced surface-solution equilibrium at low bulk concentration — substantive deposition from favourable interfacial versus bulk partitioning.

Typically Found In: Shampoos,conditioners,leave-in products
