Ingredients Details
Actinidia Chinensis (kiwi) Fruit Extract
Common Name(s): Actinidia chinensis (kiwi) fruit extract,botanical extract,phytochemical active
CAS Number: N/a
DESCRIPTION
What It Does: Provides antioxidant protection from reactive oxygen species, reduces inflammatory cytokine production in skin, and conditions skin surface through the plant's secondary metabolite complex.
Why It's Used: Chosen for its natural origin narrative, traditional use heritage, and multi-functional phytochemical profile that supports several concurrent skin care claims from one ingredient.
How It Works: Polyphenols, terpenoids, and alkaloids in the extract scavenge ros via hydrogen atom transfer, inhibit nf-kb or cox-2 inflammatory pathways, and interact with skin surface proteins for conditioning.
Typically Found In: Botanical skin care,natural products
TECHNICAL DETAILS
Primary Category: Active ingredient โ 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%โ10%
SOURCING & ETHICS
Vegan Status: Yes

Ascorbyl Glucoside
Common Name(s): Aa2g,2-o-alpha-d-glucopyranosyl-l-ascorbic acid
CAS Number: 129499-78-1
DESCRIPTION
What It Does: Provides stable gradual-release vitamin c activity for brightening and antioxidant protection.
Why It's Used: Most formulation-stable vitamin c derivative โ ascorbyl glucoside remains stable in aqueous formulations where pure ascorbic acid oxidises within days, providing sustained vitamin c delivery over weeks of shelf life.
How It Works: Alpha-glucoside bond resists oxidation until cleaved by skin alpha-glucosidase enzymes. releases free l-ascorbic acid in viable epidermis. released ascorbic acid inhibits tyrosinase, stimulates collagen synthesis, and provides antioxidant activity. glucose group provides enhanced water solubility vs ascorbic acid.
Typically Found In: Stable vitamin c serums,brightening products,anti-aging
TECHNICAL DETAILS
Primary Category: Active ingredient โ stable vitamin c glucoside
Secondary Functions: Tyrosinase inhibitor,collagen cofactor
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ5%
SOURCING & ETHICS
Vegan Status: Yes โ enzymatic synthesis from ascorbic acid and glucose
Halal Status: Yes
Source Notes: Synthetically produced vitamin c derivative.
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: Tocopherol,ferulic acid,niacinamide,spf
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Ascorbyl glucoside's stability advantage (18+ months in aqueous formulation vs days for ascorbic acid) arises from the glucose group's steric protection of ascorbic acid's c2 enediol that is the primary oxidation site. glucosidase cleavage in skin removes this protection in situ, releasing active ascorbic acid only where enzymatic activity exists โ providing both formulation stability and bioactivation where needed.

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.
