Betaine
Common Name(s): Trimethylglycine,tmg,natural betaine
CAS Number: 107-43-7
DESCRIPTION
What It Does: Provides osmoprotective humectant conditioning with anti-irritant and mild foam-boosting activity.
Why It's Used: Natural-origin multifunctional osmolyte from sugar beet providing hydration, anti-irritancy, and conditioning in virtually every cosmetic category.
How It Works: Quaternary ammonium betaine provides zwitterionic character for water binding via ionic hydration. osmoprotective function at 100โ500mm as compatible solute protecting cells from osmotic stress. reduces surfactant irritation by competing with sls for protein binding sites. mild foam enhancement.
Typically Found In: Virtually all categories โ moisturisers, shampoos, cleansers
TECHNICAL DETAILS
Primary Category: Functional ingredient โ humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.5%โ10%
SOURCING & ETHICS
Vegan Status: Yes โ from beta vulgaris (sugar beet) molasses
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Betaine's anti-irritant mechanism for surfactant systems involves competitive protein protection: betaine at high concentrations preferentially interacts with skin proteins, occupying binding sites that would otherwise be occupied by surfactant molecules causing protein denaturation. this competition reduces available protein binding for irritating surfactants, explaining betaine's well-documented ability to reduce sls irritation when co-formulated.

Bis-aminopropyl Diglycol Dimaleate
Common Name(s): Bis-aminopropyl diglycol dimaleate
DESCRIPTION
What It Does: Delivers targeted skin-conditioning or bioactive benefits through a specific mechanism of action suited to the formulation's intended purpose.
Why It's Used: Specialty actives address specific skin concerns through targeted molecular mechanisms, providing efficacy beyond what base formulation ingredients alone can achieve.
How It Works: The bioactive compound interacts with specific molecular targets in skin cells or the extracellular matrix โ enzymes, receptors, structural proteins, or signaling molecules โ triggering beneficial biological responses.
Typically Found In: Serums,treatments,moisturizers,specialty products
TECHNICAL DETAILS
Primary Category: Specialty actives
Secondary Functions: Skin-conditioning,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.01โ5%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Specialty active ingredient; check individual sourcing for vegan status.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 0
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,peptides
Avoid Combining With: Incompatible with oxidizing agents; check ph stability
SCIENTIFIC NOTE
Specialty actives typically work through enzyme inhibition (e.g., tyrosinase inhibition for brightening, mmp inhibition for anti-aging), receptor activation (e.g., retinoid receptors, ppar-ฮณ for barrier genes), or transcription factor modulation (e.g., nrf2 for antioxidant gene upregulation). structure-activity relationships determine potency and selectivity.

Citral
Common Name(s): 3,7-dimethyl-2,6-octadienal,geranial+neral mix
CAS Number: 5392-40-5
DESCRIPTION
What It Does: Provides the defining intense lemon-citrus fragrance note.
Why It's Used: The lemon scent compound โ citral defines the fresh lemon scent in lemon essential oil and lemongrass with potent antimicrobial activity.
How It Works: Mixture of e-isomer (geranial) and z-isomer (neral). antimicrobial via michael addition to thiol enzymes. inhibits nf-kb for anti-inflammatory activity. antioxidant via allylic aldehyde.
Typically Found In: Citrus fragrances,antibacterial products,lemon-scented cosmetics
TECHNICAL DETAILS
Primary Category: Fragrance component โ lemon aldehyde
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.001%โ0.5%
SOURCING & ETHICS
Vegan Status: Yes โ from lemon, lemongrass, melissa oils
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ 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. high sensitisation potential from alpha,beta-unsaturated aldehyde structure. ifra strict limits.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Citral's high sensitisation potential (llna ec3 ~0.11%) is a consequence of its alpha,beta-unsaturated aldehyde structure providing a highly reactive michael acceptor for skin protein covalent binding. the e/z mixture (geranial/neral) in natural citral means both isomers contribute to the sensitisation burden โ explaining why lemongrass oil (very high citral content, ~60-80%) is one of the more common essential oil allergens.
