Love Earth Vitamin C Sunscreen SPF-50 for UVAUVB Ray Protection with Vitamin C & Essential Oils

DESCRIPTION

What It Does: Provides combined uva and uvb filtration in a single chemical uv filter molecule.

Why It's Used: Combined uva+uvb filter historically used for broad-spectrum coverage in a single ingredient, now increasingly restricted.

How It Works: Benzophenone chromophore absorbs uvb (305nm) and uva-ii (326nm) via two separate n→π* transitions. water-soluble allows aqueous phase formulation. single filter providing partial broad-spectrum coverage.

Typically Found In: Sunscreens (being phased out in many markets)

SAFETY & COMPATIBILITY

Safety Profile: Eu max 6%. coral reef/aquatic toxicity — banned hawaii, palau, some us states. potential endocrine activity at high systemic exposure. ewg score: 7. use declining due to regulatory pressure.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Benzophenone-3's declining use reflects evolving understanding of environmental and endocrine impacts: discovered in coral bleaching studies, its restriction in hawaii (2018) sparked a global trend in marine-safe sunscreen formulations that is reshaping the industry away from bp-3 toward mineral filters and marine-safer organic alternatives.

DESCRIPTION

What It Does: Provides high-hlb o/w emulsification for stable cream formation from ethoxylated cetearyl alcohol.

Why It's Used: Classic self-emulsifying wax component for standard pharmaceutical and cosmetic cream formulation.

How It Works: 20 eo units on cetearyl alcohol chain provide hlb ~15-17 for strong o/w emulsification. often pre-blended with cetearyl alcohol as 'emulsifying wax' for simplified cream making. combined low-hlb cetearyl alcohol + high-hlb ceteareth-20 forms a balanced self-emulsifying system.

Typically Found In: Classic pharmaceutical and cosmetic creams

TECHNICAL DETAILS

Primary Category: Functional ingredient – ethoxylated fatty alcohol emulsifier

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 1%–8%

SOURCING & ETHICS

Vegan Status: Conditional – peg petroleum; cetearyl vegetable

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

Ceteareth-20's combination with cetearyl alcohol in the classic 'emulsifying wax nf' creates what is called a 'mixed emulsifier system' where the fatty alcohol forms lamellar crystal phases that physically trap and stabilize oil droplets. this physical (lamellar crystal) + chemical (hlb balance) dual stabilization provides superior stability compared to either component alone.

DESCRIPTION

What It Does: Provides a dry, weightless application vehicle that evaporates cleanly leaving actives and non-volatile silicones deposited on skin — eliminating the residual heaviness of conventional liquid carrier solvents.

Why It's Used: Cyclosiloxanes are the unique volatile silicone solvents that dissolve non-volatile silicones (dimethicone, cyclomethicone), organic uv filters, and lipophilic actives, providing the sensory-superior dry-touch application experience in premium formulations.

How It Works: Cyclosiloxane vapour pressure (d5 cyclopentasiloxane ~0.3 mmhg at 25°c) provides clean evaporation at body temperature. the cyclic ring structure provides lower boiling point than equivalent linear dimethicone, enabling faster evaporation while the ring conformation maintains the silicone's low surface energy for smooth application.

Typically Found In: Primers,antiperspirants,sunscreens

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Cyclopentasiloxane (d5) and cyclohexasiloxane (d6) are under eu regulatory review for potential environmental persistence (pbt assessment) — formulators should monitor eu regulation 2018/35 implementation for restrictions in wash-off products.

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

Body Care

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

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.
