Deep Cleansing Bar 3PK

DESCRIPTION

What It Does: Provides emollient skin conditioning with specific spreading value determined by the acid-alcohol ester molecular architecture.

Why It's Used: Butyl avocadate is selected for the specific functional properties of its molecular class — the chemical architecture of butyl avocadate delivers the required cosmetic performance through documented interactions with skin biology and formulation matrix.

How It Works: Ester polarity (logp) controls spreading: branched short-chain fast dry; medium moderate spreading; long chain occlusive. ester c=o provides polar adhesion to skin.

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.

DESCRIPTION

What It Does: Provides hygroscopic moisture retention and co-solvent activity for active ingredient dissolution from the polyether backbone's multiple ether oxygen water-binding groups.

Why It's Used: Peg molecular weight determines primary function: low mw (co-solvent/humectant), medium mw (emulsifier/solubiliser), high mw (film-former/thickener) — enabling the same chemical class to address multiple formulation needs across the mw range.

How It Works: Peg ether oxygens (1 per ch₂ch₂o repeat unit) provide 2-3 h-bond acceptors per unit — the chain of ether oxygens binding water molecules creating the hygroscopic character. at low mw (liquid state), provides co-solvent dissolution; at high mw (waxy solid), provides film-forming character through chain entanglement.

Typically Found In: Versatile formulations

DESCRIPTION

What It Does: Reduces surface tension at oil-water interfaces, enabling effective cleansing, emulsification, and formulation stability.

Why It's Used: Surface-active agents are essential for emulsification, cleansing, and stabilization of cosmetic formulations containing both aqueous and lipid phases.

How It Works: The amphiphilic molecular structure positions the hydrophilic head in water and the lipophilic tail in oils, creating micelles that solubilize sebum, dirt, and oil-soluble impurities for rinsing in cleansers or stable emulsions in leave-on products.

Typically Found In: Cleansers,shampoos,body washes,foaming treatments

TECHNICAL DETAILS

Primary Category: Surfactants

Secondary Functions: Emulsifying,cleansing

Application Areas:

Halal Status: Yes

Source Notes: Synthetic or semi-synthetic surfactant; no animal components.

SKIN COMPATIBILITY

Irritancy Rating: 1900-01-01 00:00:00 -0800

Sensitivity Concerns: May cause irritation or stinging in sensitive or barrier-compromised skin at high concentrations; patch test recommended.

Safe for Sensitive Skin: Conditional

SAFETY & COMPATIBILITY

Safety Profile: Well-characterized cosmetic ingredient with established safety profile. mildly irritating to some individuals at typical use concentrations. suitable for leave-on and rinse-off cosmetics.

Works Well With: Other surfactants,thickeners,conditioning agents

Avoid Combining With: High concentrations in sensitive skin formulations

SCIENTIFIC NOTE

Surfactant critical micelle concentration (cmc) determines the threshold for emulsification: above the cmc, amphiphilic molecules self-assemble into micelles with hydrophobic cores that solubilize oils. hlb (hydrophile-lipophile balance) value predicts surfactant function: hlb 3–6 for w/o emulsifiers, 8–18 for o/w emulsifiers, >15 for solubilizers.

DESCRIPTION

What It Does: Provides excellent foaming cleansing with skin-conditioning isethionate chemistry and minimal irritation.

Why It's Used: Superior mild cleansing for sensitive skin and baby products – provides the foaming performance consumers expect with dramatically reduced irritation vs sls.

How It Works: Isethionate headgroup (2-hydroxy ethane sulfonate) reduces protein binding and denaturing vs sulfate. coconut fatty acid chain provides micelle formation. skin conditioning from the isethionate's hydroxyl group. very low irritation zein test score.

Typically Found In: Gentle cleansers,baby products,sensitive skin bars,shampoos

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

Sci's exceptional mildness is demonstrated by its near-zero protein denaturation in zein testing (a standard measure of surfactant aggressiveness). by comparison, sodium lauryl sulfate denatures 90% of zein protein at equivalent concentrations, while sci denatures <5%, explaining the dramatic difference in skin and eye irritation between the two surfactants.

SCIENTIFIC NOTE

Sodium stearate has an established safety profile within the cosmetic regulatory framework at standard use concentrations.

Last Verified: Cosing database,sodium stearate technical literature

Primary Sources: 2026-03-12

DESCRIPTION

What It Does: Provides gentle lathering cleansing, conditions skin with the parent fatty acid's emollient character, and acts as a natural self-emulsifying agent in soap-based cream and lotion formulations.

Why It's Used: Natural soap salts are the original cosmetic surfactants — neutralised fatty acids provide cleansing, conditioning, and emulsification from a single renewable ingredient with millennia of safe use documentation.

How It Works: Fatty acid saponification: rcooh + sodiumoh → rcoo-sodium (soap). soap micelles encapsulate sebum and dirt for rinsing. the parent fatty acid determines foam character, conditioning, and melting point. ph-sensitive: function best above ph 6 where carboxylate (ionised) form predominates.

Typically Found In: Bar soaps,classical creams

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Soap formulation ph: classical soap bars require ph 9–11 for stable carboxylate ionisation. at skin ph 5.5, partial protonation to free fatty acid occurs — providing the transition from soap (cleansing) to fatty acid (conditioning) on skin contact, explaining soap's combined clean-rinse and skin-soft feel.

DESCRIPTION

What It Does: Provides fatty acid thickening and emolliency with soap-forming emulsification when neutralized.

Why It's Used: Classic cosmetic fatty acid used in virtually all cream and lotion formulations for thickening, emolliency, and opacification.

How It Works: Forms metal soaps (sodium stearate, potassium stearate) on reaction with alkalis for self-emulsification. crystallizes in lamellar networks for thickening. waxy solid provides opacification. low-viscosity melt above 69°c for easy processing.

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

Stearic acid's dual role as both an emulsifier precursor (when saponified to sodium stearate soap) and an emollient (as unmodified fatty acid) is unique among cosmetic fatty acids. in soap-based cleansers, stearic acid is intentionally partially saponified to create a balanced system: excess stearic acid provides skin-conditioning emolliency while the sodium stearate provides surfactancy – the chemical basis for 'superfatted' soaps.
