Ingredients Details
Aminomethyl Propanol
Common Name(s): Aminomethyl propanol,cosmetic active,functional ingredient
CAS Number: N/a
DESCRIPTION
What It Does: Delivers characteristic cosmetic function at recommended use concentration.
Why It's Used: Selected for functional contribution and formulation compatibility supported by cosmetic science and regulatory safety data.
How It Works: Works through the mechanism of its molecular class — physicochemical or biological interaction with skin proteins, lipids, or receptors as documented in peer-reviewed cosmetic literature.
Typically Found In: Skin care formulations
TECHNICAL DETAILS
Primary Category: Active ingredient – cosmetic active
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–10%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
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
Aminomethyl propanol has an established safety and efficacy profile within the cosmetic regulatory framework at standard use concentrations.

Bambusa Vulgaris Extract
Common Name(s): Bambusa vulgaris extract
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
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
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: 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,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.

Benzyl Alcohol
Common Name(s): Phenylcarbinol,benzenemethanol,alpha-hydroxytoluene
CAS Number: 100-51-6
DESCRIPTION
What It Does: Provides dual fragrance and preservative activity as an aromatic alcohol.
Why It's Used: Multi-function ingredient serving as both fragrance component and preservative – reduces formulation complexity by providing both functions in one ingredient.
How It Works: Phenylcarbinol provides antimicrobial activity via membrane disruption (effective vs gram-positive bacteria and moulds). solvent for fragrances and difficult-to-dissolve actives. mild oxidative conversion to benzaldehyde provides sweet almond-like fragrance.
Typically Found In: Fragrances,preserved cosmetics,solvent systems
TECHNICAL DETAILS
Primary Category: Fragrance component / preservative
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%–1% (fragrance); up to 1% as preservative
SOURCING & ETHICS
Vegan Status: Yes – from toluene, or jasmine absolute
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
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. also listed as approved preservative (annex v, max 1%). dual regulatory status (fragrance + preservative) depending on function and concentration.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Benzyl alcohol's dual regulatory status (fragrance allergen and approved preservative) creates a formulation paradox: it must be listed as a fragrance allergen if present >0.001% (leave-on) regardless of whether it was added for fragrance or preservation. this regulatory dual identity means a preservative added for antimicrobial function triggers the same allergen declaration requirement as a fragrance added for scent.

Caulerpa Lentillifera Extract
Common Name(s): Caulerpa lentillifera extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant free radical scavenging from polyphenol h-atom donation, anti-inflammatory activity from nf-kb/cox pathway inhibition, and multi-active skin conditioning.
Why It's Used: Natural extracts support concurrent antioxidant, anti-inflammatory, and conditioning skin care claims with authentic botanical heritage and traditional use backing.
How It Works: Polyphenol catechol groups donate h-atoms to ros quenching radical chain reactions (dpph-type scavenging rate constants 10^6-10^9 m^-1 s^-1). terpenoids inhibit ikb kinase blocking nf-kb nuclear translocation. flavonoids compete with arachidonic acid at cox-1/cox-2 active sites reducing prostaglandin synthesis.
Typically Found In: Botanical skin care
TECHNICAL DETAILS
Primary Category: Active ingredient – antioxidant
Secondary Functions: Free radical scavenging,anti-aging
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–30%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Conditional
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; well-tolerated.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Vitamin c,vitamin e,ferulic acid,spf,other antioxidants
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Plant secondary metabolites evolved under uv and pathogen selection pressure — the same photoprotective and antimicrobial chemistry directly translates to cosmetic antioxidant and anti-inflammatory claims in human skin.
