Mamaearth Tea Tree Face Scrub with Tea Tree and Neem for Skin Purification (100 gm)

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: 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

DESCRIPTION

What It Does: Provides mould and yeast focused broad-spectrum preservation in a widely accepted food-grade preservative.

Why It's Used: Standard mould and yeast preservative — potassium sorbate is effective at slightly higher ph than sodium benzoate, making it the preferred sorbate preservative for formulations at ph 4.5-6.

How It Works: Inactive salt form — sorbic acid (free acid, pka 4.76) is active. more effective than benzoate at higher ph (pka 4.76 vs benzoate 4.2). active at ph up to ~6.0 (meaningful sorbic acid present). inhibits malassezia and candida at lower concentrations than bacteria. synergistic with sodium benzoate.

Typically Found In: Cosmetics ph 4-6,natural preservation systems,combined with sodium benzoate

TECHNICAL DETAILS

Primary Category: Functional ingredient – sorbate preservative

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

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: Eu max 0.6% cosmetics. fda gras. synergistic with sodium benzoate. oxidises to sorbaldehyde (yellow colouration) on uv exposure — protect from light.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Potassium sorbate's antifungal mechanism (disruption of mitochondrial electron transport in fungi) is different from its antibacterial mechanism (cell membrane and enzyme disruption). this mechanistic bifunctionality provides broad spectrum from a single preservative, though the lower antifungal mic values mean mould and yeast protection is achieved at lower concentrations than bacterial protection.

DESCRIPTION

What It Does: Preserves acidic formulations against yeast and mold contamination.

Why It's Used: Natural-derived (from benzoic acid found in cranberries, cinnamon) preservative for acidic ph formulations where it provides excellent antimicrobial activity.

How It Works: Undissociated benzoic acid (active form, pka 4.2) penetrates microbial cell membranes and disrupts electron transport chain and ph homeostasis. at ph>5, mostly ionized (sodium salt) and inactive – requires acidic formulation ph for efficacy.

Typically Found In: Acidic serums,toners,low-ph formulations

SAFETY & COMPATIBILITY

Safety Profile: Eu max 0.5%. gras food additive. ewg score: 3 (benzene formation concern with vitamin c at >80°c – normal use temperatures do not form benzene).

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Sodium benzoate's strict ph dependency (90% inactive at ph>5.5) makes its preservative activity dramatically sensitive to formulation ph. a serum formulated at ph 4.0 is fully preserved by benzoate; the same formula adjusted to ph 5.5 has <10% of the preservative activity. this ph dependency must be considered in any benzoate-preserved formulation.
