Skin Protect Lipid Cream

DESCRIPTION

What It Does: Softens and conditions skin by integrating into sc lipid bilayers, delivers essential fatty acids (oleic, linoleic, linolenic) for barrier lipid synthesis, and provides rich, non-stripping moisturisation.

Why It's Used: Natural carrier oils provide the closest compositional match to endogenous sc lipids, delivering emolliency through genuine barrier integration rather than simple surface occlusion.

How It Works: Fatty acid triglycerides partition into sc lipid bilayers — oleic acid (c18:1) provides fluid, emollient integration; linoleic acid (c18:2) acts as essential ceramide precursor; saturated fatty acids provide more occlusive barrier reinforcement.

Typically Found In: Moisturisers,facial oils,natural skin care

DESCRIPTION

What It Does: Provides fatty alcohol emulsification and thickening for stable, well-textured emulsions.

Why It's Used: The most widely used fatty alcohol in cosmetics – provides emulsification, thickening, and emolliency simultaneously from a single ingredient with excellent safety profile.

How It Works: Forms bilayer lamellar structures in water with emulsifiers creating a viscous structured network that thickens and stabilizes emulsions. fatty alcohol emolliency provides direct skin conditioning. bilayer formation reduces inter-droplet coalescence in emulsions.

Typically Found In: Creams,lotions,conditioners – virtually all emulsion products

TECHNICAL DETAILS

Primary Category: Functional ingredient – fatty alcohol emulsifier/thickener

Secondary Functions: Barrier sealing,softening

Application Areas:

Facial Skincare

Body Care

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

Cetearyl alcohol's ability to form lamellar liquid crystal structures ('krafft phases') with water and co-emulsifiers provides not only emulsion stability but also enhanced skin penetration via the lamellar skin barrier pathway. these crystalline structures can act as a reservoir for active ingredients, slowly releasing them as the lamellar structure melts on skin contact.

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.

Typically Found In: Moisturizers,serums,cleansers,toners,sheet masks,sunscreens,body lotions,shampoos,conditioners

TECHNICAL DETAILS

Primary Category: Humectant

Secondary Functions: Skin barrier support,emollient,solvent

Application Areas:

Facial Skincare

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 1%–30% (typical: 3–10%)

SOURCING & ETHICS

Vegan Status: Yes – plant-derived (coconut, soy, palm) or synthetic

Halal Status: Yes – when plant-derived or synthetic; verify source with supplier

Source Notes: Derived from plant oils via hydrolysis or saponification; synthetic versions also available. palm-derived glycerin carries sustainability concerns.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low; non-irritating at all standard concentrations

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Extremely rare allergic reactions; generally safe for all skin types including sensitive and baby skin

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Widely recognized as safe. ewg hazard score: 1. no significant concerns for irritation, sensitization, or toxicity at typical concentrations (up to 50%).

Works Well With: Hyaluronic acid,ceramides,niacinamide,panthenol,urea,peptides,retinol,ahas/bhas

Avoid Combining With: No known incompatibilities at standard concentrations

SCIENTIFIC NOTE

Glycerin is an endogenous skin component found naturally in the stratum corneum. aquaporin-3 channels in keratinocytes facilitate glycerin transport, making it integral to natural skin hydration pathways.

DESCRIPTION

What It Does: Stabilises o/w emulsions by forming a molecular monolayer at the oil-water interface, provides co-emulsification synergy with other emulsifiers, and contributes to emulsion texture through interfacial film properties.

Why It's Used: Nonionic emulsifiers are preferred for sensitive skin and ph-extreme formulations — no ionic charge means no electrostatic interaction with skin proteins, no ph-dependent function loss, and compatibility with both anionic and cationic co-ingredients.

How It Works: Hlb determines emulsion type: hlb 8–12 for o/w emulsification; hlb 3–6 for w/o. the peg or glycoside head group provides hydrophilicity while the c16–c18 fatty chain provides lipophilicity. at the o/w interface, nonionic emulsifiers form a mixed monolayer reducing interfacial tension from ~35 mn/m (clean oil-water) to 5–10 mn/m, providing thermodynamic stabilisation.

Typically Found In: Creams,lotions,o/w emulsions

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

Mixed emulsifier systems (e.g., glyceryl stearate + peg-100 stearate, or cetearyl glucoside + cetearyl alcohol) provide better emulsion stability than single emulsifiers — synergistic packing of different molecular geometries creates a more cohesive, mechanically robust interfacial film.

DESCRIPTION

What It Does: Softens and conditions skin with a light, non-greasy feel.

Why It's Used: Used for its stable olive-derived non-greasy emollient; oxidation-resistant vs standard ethylhexyl olivate emollient properties; suitable for lightweight skin care where non-greasy texture is key.

How It Works: Ester of 2-ethylhexanol (branched or specialty alcohol) with hydrogenated olive oil fatty acids; branching reduces crystallinity and greasiness; provides smooth, dry-oil skin feel.

Typically Found In: Lightweight moisturizers,sunscreens,skin serums,body lotions

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1.

Works Well With: Other emollients,silicones,natural oils,humectants

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Hydrogenated ethylhexyl olivate: 2-ethylhexyl ester of hydrogenated olive oil fatty acids; hydrogenation converts oleic/palmitic to stearic/palmitic; greatly improved oxidative stability vs standard ethylhexyl olivate while maintaining the non-greasy feel.

DESCRIPTION

What It Does: Nourishes and softens skin through its balanced fatty acid profile, while antioxidant compounds protect against oxidative skin damage.

Why It's Used: Plant oils provide physiologically compatible lipid structures that integrate into the skin barrier and deliver fat-soluble antioxidants directly to skin cells.

How It Works: Fatty acids integrate into stratum corneum lipid lamellae, reinforcing the lipid barrier. antioxidants (tocopherols, carotenoids, polyphenols) neutralize ros through electron donation or singlet oxygen quenching.
