Guardian Rice Milk Moisturising Shower Cream 500Ml

DESCRIPTION

What It Does: Boosts foam, enhances mildness, and conditions skin and hair when combined with primary surfactants.

Why It's Used: The standard foam booster and mildness enhancer in virtually all shampoos, body washes, and facial cleansers – provides synergistic mildness improvement with anionic surfactants.

How It Works: Amphoteric (zwitterionic) character provides positive charge interaction with hair keratin for antistatic conditioning. reduces irritation of co-formulated anionic surfactants via ionic complex formation. foam stabilization via bilayer reinforcement in foam lamellae.

Typically Found In: Shampoos,body washes,facial cleansers,baby products

SCIENTIFIC NOTE

Capb's mildness-enhancing synergy with sls has a molecular mechanism: capb's positive imidazoline head group forms an ion pair complex with sls's anionic sulfate group, reducing sls's free monomer concentration (the irritation-causing species) without significantly reducing micelle-forming capacity (the cleansing species).

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

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: Boosts foam quality, stabilises foam lamellae, builds viscosity in surfactant systems, and reduces surface tension in cleansing formulations.

Why It's Used: Dea alkanolamides face n-nitrosamine formation concerns (eu restriction from leave-on use) — formulators transition to mea or mipa equivalents for cleaner regulatory positioning.

How It Works: Amide nitrogen lone pair inserts at foam bubble air-water interface alongside the fatty acid chain — the amide geometry stabilises foam lamellae through the gibbs-marangoni effect reducing drainage. viscosity building in surfactant systems arises from rod micelle formation above critical packing parameter.

Typically Found In: Shampoos,body wash,cleansers

DESCRIPTION

What It Does: Provides excellent foam and cleansing with significantly lower irritation than sls.

Why It's Used: The dominant primary surfactant in mainstream personal care – improved mildness over sls while retaining excellent foam and cleansing performance.

How It Works: Ethoxylation (2-3 eo units) inserts polyethylene oxide spacer between dodecyl chain and sulfate, sterically shielding sulfate from direct protein contact, reducing irritation vs sls. full micellar cleansing capacity retained.

Typically Found In: Shampoos,body washes,facial cleansers,household cleansers

TECHNICAL DETAILS

Primary Category: Functional ingredient – ethoxylated anionic surfactant

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 2%–15%

SOURCING & ETHICS

Vegan Status: Yes – from coconut fatty acids

Halal Status: Yes

Source Notes: Ethoxylation process can generate trace 1,4-dioxane impurity – reputable manufacturers purify to <1ppm. look for sles certified with dioxane specification.

SKIN COMPATIBILITY

Irritancy Rating: 2/5 – low to moderate (significantly milder than sls)

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Well-tolerated by most skin types.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Well-established safety. ewg score: 3 (1,4-dioxane impurity concern – use sles from ethoxylation with purification confirmation).

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Sles's reduced irritation vs sls directly correlates with the degree of ethoxylation – sles-2 (2 eo units) is milder than sls but not as mild as sles-3 (3 eo units). each ethylene oxide unit adds steric shielding around the sulfate group, progressively reducing its protein-binding and denaturation capacity.

DESCRIPTION

What It Does: Provides edta chelation in alkaline formulations where disodium edta has limited solubility.

Why It's Used: Alkaline-ph edta chelation for cleansers and alkaline formulations requiring metal sequestration beyond the solubility limit of disodium edta.

How It Works: Tetrasodium salt provides greater water solubility at alkaline ph vs disodium form (pka effects). same hexadentate chelation mechanism as disodium edta. preferred in alkaline cleansers (ph 7-10). identical chelation efficacy per mole vs disodium edta.

Typically Found In: Alkaline cleansers,high ph formulations,soap-based products

TECHNICAL DETAILS

Primary Category: Functional ingredient – chelating agent alkaline

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Typical Concentration Range: 0.005%–0.1%

SOURCING & ETHICS

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

Tetrasodium edta's alkaline ph advantage reflects the ionisation state of edta carboxylate groups: at ph 7 disodium edta has two ionised carboxylates (fully soluble) and two protonated (affects solubility limit). tetrasodium edta's four sodium counterions provide four ionised carboxylates at all ph values — fully charged, fully soluble across the entire ph range.
