Redken Color Extend Magnetics Sulfate-Free Shampoo

DESCRIPTION

What It Does: Provides amino group-mediated preferential adsorption to damaged hair for targeted conditioning.

Why It's Used: Premium hair conditioning silicone – amino groups provide substantive adsorption to hair far exceeding pdms, with automatic targeting to the most damaged areas requiring conditioning.

How It Works: Amino (nh2) groups on silicone chain provide cationic character at normal ph, electrostatic adsorption to anionic hair surface. higher charge density at damaged sites increases adsorption where conditioning is most needed. si-o-si backbone provides permanent conditioning film with heat protection.

Typically Found In: Intensive conditioners,anti-frizz products,damage repair conditioners

DESCRIPTION

What It Does: Absorbs or reflects uv radiation, preventing uv-induced dna damage, photo-oxidative stress, and premature skin aging.

Why It's Used: Uv filters are the active ingredients in sun protection — without them, formulations cannot make spf claims or prevent solar-induced skin damage.

How It Works: The uv-absorbing chromophore undergoes photoexcitation by uv photons, then dissipates the absorbed energy through thermal relaxation (chemical filters) or photon scattering/reflection (physical filters), preventing photon penetration to skin cells.

Typically Found In: Sunscreens,moisturizers with spf,foundations with spf

TECHNICAL DETAILS

Primary Category: Uv filters

Secondary Functions: Skin-protecting

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.5–25% (within regulatory limits)

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Synthetic uv filter; no animal components.

SKIN COMPATIBILITY

Irritancy Rating: 1

Comedogenicity Rating: 0

Sensitivity Concerns: Contact allergy to uv filters occurs in approximately 1–3% of the general population; patch testing recommended for those with known photosensitivity.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Regulatory approval required per market (eu annex vi, fda otc monograph, etc.). generally non-irritating at approved concentrations.

Works Well With: Other uv filters,antioxidants,emollients

Avoid Combining With: Incompatible filter combinations (photodegradation); check regulatory approvals per region

SCIENTIFIC NOTE

Uv filters operate through two mechanisms: organic/chemical filters absorb uv photons through electronic excitation (π→π* transitions in conjugated systems), then dissipate energy via thermal relaxation; inorganic/physical filters (tio2, zno) scatter and reflect photons through mie scattering (particle size 50–300 nm) and band gap absorption. spf is measured in vivo (iso 24444) as the ratio of minimal erythema doses with and without sunscreen.

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

Primary Category: Functional ingredient – polyacrylic acid thickener

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

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.

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 – 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.

DESCRIPTION

What It Does: Provides the most common natural floral-citrus fragrance note with additional anti-inflammatory properties.

Why It's Used: The most abundant fragrance terpene in nature – linalool forms the primary scent character of lavender, responsible for lavender's documented aromatherapy calming effects.

How It Works: Monoterpene alcohol activates gaba-a receptors for anti-anxiety activity (same receptor as benzodiazepines). inhibits glutamate-induced excitotoxicity. antimicrobial via membrane disruption. anti-inflammatory via nf-kb inhibition.

Typically Found In: Virtually all fragranced cosmetics

SCIENTIFIC NOTE

Linalool's gaba-a receptor activation provides a pharmacological basis for lavender aromatherapy's documented anxiolytic effects. the same receptor modulation used by benzodiazepine drugs (such as diazepam) is activated by inhaled linalool vapor, providing receptor-mediated calming without the tolerance and dependence associated with pharmaceutical gaba-a modulators.
