Dimethicone
Common Name(s): Pdms,polydimethylsiloxane,silicone fluid
CAS Number: 9006-65-9
DESCRIPTION
What It Does: Provides silicone-characteristic silky feel and skin protection with adjustable viscosity.
Why It's Used: The benchmark cosmetic silicone โ sets the gold standard for silky application feel, spreadability, and skin protection in virtually all skin care categories.
How It Works: Polydimethylsiloxane chain flexibility provides extremely low surface tension and high spreadability. inert si-o backbone provides chemical stability and excellent skin tolerance. occlusive film formation reduces tewl. higher viscosity grades provide more intense conditioning.
Typically Found In: Moisturizers,foundations,primers,sunscreens โ nearly universal
TECHNICAL DETAILS
Primary Category: Functional ingredient โ polydimethylsiloxane
Secondary Functions: Barrier sealing,softening
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%โ30%
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
Halal Status: Yes
Source Notes: Plant-derived, synthetic or animal-derived. verify source.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 1/5 โ low; formulation-dependent
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Dimethicone's exceptional silky feel arises from its very low intermolecular attractive forces (weak van der waals forces due to non-polar methyl groups) that allow silicone chains to slide freely over skin. the coefficient of kinetic friction for pdms against skin (~0.04) is among the lowest of any cosmetic material โ explaining why even small amounts transform product feel.

Hydroxyacetophenone
Common Name(s): Para-hydroxyacetophenone,piceol,4-acetylphenol
CAS Number: 99-93-4
DESCRIPTION
What It Does: Provides antioxidant and preservative-boosting activity in a naturally-occurring clean-label phenolic.
Why It's Used: Clean-label preservation support โ hydroxyacetophenone provides antioxidant and antimicrobial-boosting properties from a naturally-occurring compound accepted in natural cosmetic certifications.
How It Works: Para-hydroxyl group provides antioxidant radical scavenging. disrupts bacterial cell membrane penetration for preservative system boosting. anti-inflammatory via nf-kb inhibition. occurs naturally in plants including pear and raspberry as a secondary metabolite.
Typically Found In: Natural preservation systems,antioxidant serums,clean beauty
TECHNICAL DETAILS
Primary Category: Functional ingredient โ antioxidant preservative booster
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%โ1%
SOURCING & ETHICS
Vegan Status: Yes โ natural from plants or synthetic
Halal Status: Yes
Source Notes: Plant-derived extract or synthetic.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ 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
Hydroxyacetophenone's natural occurrence in fruits (pear, raspberry, passion fruit) at detectable concentrations provides clean-label justification for use in natural cosmetics. its cosmos certification acceptance reflects the growing demand for functional preservation ingredients that meet natural certification criteria โ an ingredient with genuine plant-origin credentials that provides meaningful antimicrobial and antioxidant functions simultaneously.

Octocrylene
Common Name(s): 2-ethylhexyl 2-cyano-3,3-diphenylacrylate
CAS Number: 6197-30-4
DESCRIPTION
What It Does: Provides uvb-uva-ii uv protection and essential avobenzone photostabilisation.
Why It's Used: The essential combination partner โ octocrylene's dual uv filter + avobenzone photostabilisation function makes it virtually irreplaceable for durable broad-spectrum chemical sunscreens requiring uva-i coverage.
How It Works: Cyanocinnamate chromophore absorbs uvb-uva-ii (ฮปmax 303nm). triplet energy transfer from excited avobenzone to octocrylene photostabilises avobenzone (>90% efficiency at 3:1 avobenzone:octocrylene ratio). hydrophobic character enhances water resistance.
Typically Found In: Broad-spectrum sunscreens,avobenzone-containing formulas
TECHNICAL DETAILS
Primary Category: Active ingredient โ uv filter and photostabiliser
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: Up to 10% (eu), 10% (us fda)
SOURCING & ETHICS
Vegan Status: Yes โ synthetic
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 max 10%. fda: 10%. ewg score: 3. recent benzophenone impurity concerns from aged product hydrolysis under study.
Works Well With: Standard skincare actives
Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Octocrylene's triplet energy transfer photostabilisation of avobenzone operates via a dexter electron exchange mechanism: excited-state avobenzone (triplet) transfers excitation energy to octocrylene via orbital overlap, allowing avobenzone to return to its ground state uv-absorbing form without photodegradation. this energy transfer is only efficient at close molecular proximity โ requiring intimate mixing of the two compounds in the formulation oil phase.
