Kenra Professional Daily Provision

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

SCIENTIFIC NOTE

Amodimethicone's amino group-driven substantivity to damaged hair is dramatically greater than non-functionalized pdms. studies show amodimethicone deposits 50-200× more mass on bleach-damaged hair vs virgin hair, providing an automatic 'damage detection' conditioning system that directs the most conditioning to the hair areas that need it most.

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 antioxidant protection, soothing anti-inflammatory effects, and skin-conditioning benefits through plant-derived polyphenols and phytochemicals.

Why It's Used: Plant extracts concentrate bioactive phytochemicals evolved for environmental protection — uv, microbial, and oxidative stressors — that translate to skin benefits.

How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-κb-mediated inflammatory signaling, scavenge reactive oxygen species through electron donation, and chelate pro-oxidant metal ions to reduce oxidative skin damage.

Typically Found In: Serums,toners,moisturizers,masks,essences

TECHNICAL DETAILS

Primary Category: Botanical extracts

Secondary Functions: Antioxidant,anti-inflammatory

Application Areas:

Facial Skincare

Typical Concentration Range: 0.1–10%

SOURCING & ETHICS

Vegan Status: Yes

Halal Status: Yes

Source Notes: Plant-derived extract; no animal components.

SKIN COMPATIBILITY

Irritancy Rating: 1899-12-31 00:00:00 -0800

Sensitivity Concerns: Low sensitization potential at recommended use concentrations.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.

Works Well With: Niacinamide,hyaluronic acid,vitamin c,ceramides

Avoid Combining With: Strong oxidizing agents

SCIENTIFIC NOTE

Plant secondary metabolites (flavonoids, terpenes, phenolic acids) are biosynthesized as defense compounds against uv, herbivores, and pathogens. their anti-inflammatory activity typically derives from competitive inhibition of cox-2 and 5-lox enzymes (ic50 1–50 µm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.

DESCRIPTION

What It Does: Provides co-solvent and penetration enhancer in cosmetic formulations, improving active ingredient dissolution and product texture while delivering mild skin conditioning.

Why It's Used: Glycol solvents are essential for dissolving actives with limited water or oil solubility — the intermediate polarity of glycol ethers provides access to the wider solubility parameter space between pure water and oil phases.

How It Works: Hydroxyl and ether groups provide h-bonding for water miscibility; the organic chain provides compatibility with lipophilic actives. medium-chain glycols (c3–c6) provide the optimal balance of water compatibility, lipophilic active dissolution, and skin-compatible humectancy.

Typically Found In: Skin care formulations,co-solvent systems

DESCRIPTION

What It Does: Deposits conditioning protein film on skin and hair through electrostatic and h-bonding surface adsorption, provides amino acid humectancy, reduces friction and improves combability in hair, and temporarily smooths skin surface texture.

Why It's Used: Hydrolysed proteins provide dual-weight-dependent function: high-mw fractions (>5000 da) adsorb on surfaces for film-forming conditioning; low-mw fractions (<500 da) penetrate sc for deeper conditioning and metabolic amino acid delivery.

How It Works: Enzymatic hydrolysis yields a distribution of peptide fragments 100–10,000 da. positively charged (basic) amino acid residues (lysine, arginine) in the peptide fragments electrostatically bind the negatively charged hair cuticle surface; hydrophobic residues provide lipophilic anchoring. the resulting protein film reduces tewl and surface friction while providing amino acid nutrients.

Typically Found In: Hair conditioners,skin serums,protein formulas

SCIENTIFIC NOTE

Nettle's paradox as a topical ingredient is that the same plant that causes severe stinging on contact (from formic acid, histamine, and serotonin in the hollow stinging hairs) provides significant anti-inflammatory activity when properly extracted without the stinging compounds. aqueous or ethanolic extracts carefully filtered to remove the stinging hairs retain only the beneficial leaf polyphenol and sterol content without any stinging properties.
