Schwarzkopf Professional BC Oil Innocence Oil Shampoo

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.

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: 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

TECHNICAL DETAILS

Primary Category: Fragrance component – tertiary terpene alcohol

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

DESCRIPTION

What It Does: Provides film-forming conditioning and detangling with heat protection in a polymer that adsorbs substantively to hair.

Why It's Used: The most widely used cationic polymer conditioner – provides excellent conditioning and detangling while adsorbing strongly to damaged hair areas that need conditioning most.

How It Works: Cationic quaternary ammonium groups along the polymer backbone adsorb to anionic sites on hair keratin. higher charge density on damaged hair (more negative sites) leads to preferential adsorption where conditioning is needed. polymer film formation provides heat protection and volume.

Typically Found In: Shampoos,2-in-1 products,conditioners,styling products

TECHNICAL DETAILS

Primary Category: Functional ingredient – cationic polymer conditioner

Secondary Functions: Skin conditioning

Application Areas:

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile at recommended concentrations. ewg score: 1–2.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Polyquaternium-10's 'self-targeting' to damaged hair sites is a unique smart conditioning mechanism. as hair damage increases negative charge density by exposing keratin's aspartate and glutamate carboxylate groups, pq-10's cationic polymer backbone adsorbs preferentially to these high-charge damage sites – automatically delivering more conditioning where the hair needs it most.
