Facial Soap

DESCRIPTION

What It Does: Provides colour in cosmetic formulations within the permitted application areas and concentrations specified by fda 21 cfr 73/74 and eu cosmetics regulation annex iv.

Why It's Used: Regulatory compliance requires verifying both the permitted use category (fd&c, d&c, ext. d&c) and the specific application area approval for each colorant in each target market.

How It Works: Colour arises from selective wavelength absorption by the chromophore structure — electronic transitions (d-orbital for transition metal pigments; π→π* for organic chromophores) absorb specific visible wavelengths providing the perceived complementary colour.

Typically Found In: Colour cosmetics

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

TECHNICAL DETAILS

Primary Category: Humectant

Secondary Functions: Skin barrier support,emollient,solvent

Application Areas:

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 1%–30% (typical: 3–10%)

SOURCING & ETHICS

Vegan Status: Yes – plant-derived (coconut, soy, palm) or synthetic

Halal Status: Yes – when plant-derived or synthetic; verify source with supplier

Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low; non-irritating at all standard concentrations

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).

Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas

Avoid Combining With: No known incompatibilities at standard concentrations

SCIENTIFIC NOTE

Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.

DESCRIPTION

What It Does: Provides the highest level of skin occlusion and wound healing protection of any cosmetic ingredient.

Why It's Used: The most effective skin barrier protection ingredient available – fda-approved otc skin protectant with unparalleled occlusive moisturization and wound healing evidence.

How It Works: Semi-solid blend of long-chain hydrocarbons creates an extremely cohesive, impermeable occlusive film. physically prevents bacterial and irritant ingress while completely preventing tewl. does not absorb into skin. promotes moist wound healing environment by maintaining wound surface hydration.

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: 1899-12-31 00:00:00 -0800

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.
