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

SAFETY & COMPATIBILITY

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

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: Adjusts ph to optimal ranges, chelates destabilizing metal ions, provides mild exfoliation at higher concentrations.

Why It's Used: Universal cosmetic ph adjuster and chelating agent. aha exfoliant activity is secondary.

How It Works: As ph adjuster, donates protons. as chelating agent, three carboxylic groups bind divalent metals (ca²⁺, mg²⁺, fe²⁺) preventing oxidative degradation.

Typically Found In: Nearly all cosmetic formulations,brightening products,exfoliants

TECHNICAL DETAILS

Primary Category: Active ingredient – alpha hydroxy acid (aha)

Secondary Functions: Chelating agent,ph adjustment,preservation enhancement

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–10%

SOURCING & ETHICS

Vegan Status: Yes – synthetic or fermentation-derived

Halal Status: Yes

Source Notes: Produced by fermentation of sugars by aspergillus niger. gras (e330). most abundant organic acid in citrus.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low at low concentrations; 2/5 at exfoliant concentrations

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Photosensitizing – mandatory spf use. start at low frequency.

Safe for Sensitive Skin: Use with caution – spf required

SAFETY & COMPATIBILITY

Safety Profile: Safe at otc concentrations. eu: ≤10% leave-on at ph ≥3.5. mandatory spf advisory.

Works Well With: Niacinamide,ceramides,hyaluronic acid,spf

Avoid Combining With: Retinol in same step; multiple exfoliants simultaneously

SCIENTIFIC NOTE

Three carboxylic acid groups provide multiple proton donation sites and stronger chelation than monocarboxylic ahas. this makes citric acid the preferred cosmetic chelating agent alongside edta.

DESCRIPTION

What It Does: Provides metal ion chelation to prevent product degradation and boost preservative and antioxidant efficacy.

Why It's Used: The most essential stability ingredient in cosmetics — disodium edta's metal chelation prevents rancidity, discoloration, and preservative failure caused by trace metal contamination in virtually all aqueous cosmetic formulations.

How It Works: Ethylenediaminetetraacetic acid provides six potential coordination sites for metal ions (aminodiacetate groups). chelates ca²⁺, mg²⁺ (stability), fe³⁺ (fenton radical prevention), cu²⁺ (oxidase inhibition). disrupts gram-negative bacterial outer membrane by chelating membrane calcium, enhancing preservative penetration.

Typically Found In: Virtually all aqueous cosmetics — creams, lotions, shampoos, toners

TECHNICAL DETAILS

Primary Category: Functional ingredient – chelating agent

Secondary Functions: Skin conditioning

Typical Concentration Range: 0.005%–0.1%

SOURCING & ETHICS

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

Disodium edta's preservative potentiation against gram-negative bacteria is mechanistically elegant: gram-negative outer membranes contain lipopolysaccharide stabilised by calcium and magnesium bridges. edta chelates these metal ions, destabilising the lps layer and creating pores that allow hydrophobic preservatives (phenoxyethanol, parabens) to penetrate — converting gram-negative-resistant preservatives into broad-spectrum ones.

DESCRIPTION

What It Does: Provides the complete fragrance profile contributing to product sensory experience and consumer appeal.

Why It's Used: Fragrance is a major consumer purchase driver — up to 70% of consumers make purchasing decisions partially based on product scent.

DESCRIPTION

What It Does: Provides the oxidation power necessary for permanent hair colour development and hair lightening.

Why It's Used: The essential permanent hair colour oxidant – hydrogen peroxide provides both lightening (melanin bleaching) and dye chromophore formation in a single oxidant for complete permanent colouring.

How It Works: H2o2 at alkaline ph generates ooh⁻ (perhydroxyl anion) as the actual bleaching species. ooh⁻ oxidises melanin eumelanin in fenton-type reaction. simultaneously oxidises hair dye primary intermediates (ppd→quinonediimine) for coupling.

Typically Found In: Permanent hair colour developer,hair bleaching

TECHNICAL DETAILS

Primary Category: Hair colourant – oxidant

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

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 cosmetics regulation annex iii: max 12% in hair care products. regulated as professional-use-only above 6%. causes hair and scalp damage at high concentrations or extended exposure.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Hydrogen peroxide's hair bleaching action at alkaline ph (the developer system ph 9-11) is mediated by the perhydroxyl anion (ooh⁻) rather than h2o2 itself. the ooh⁻ concentration is governed by the ionisation equilibrium h2o2 ⇌ h⁺ + ooh⁻ (pka 11.65), meaning alkaline developer ph dramatically increases ooh⁻ concentration for efficient melanin oxidation – the chemical basis for alkali developer volumes (10v, 20v, 30v, 40v) providing different bleaching rates.

DESCRIPTION

What It Does: Deposits conditioning protein film on skin and hair through electrostatic and h-bonding surface adsorption, provides amino acid humectancy, reduces friction and improves combability in hair, and temporarily smooths skin surface texture.

Why It's Used: Hydrolysed proteins provide dual-weight-dependent function: high-mw fractions (>5000 da) adsorb on surfaces for film-forming conditioning; low-mw fractions (<500 da) penetrate sc for deeper conditioning and metabolic amino acid delivery.

How It Works: Enzymatic hydrolysis yields a distribution of peptide fragments 100–10,000 da. positively charged (basic) amino acid residues (lysine, arginine) in the peptide fragments electrostatically bind the negatively charged hair cuticle surface; hydrophobic residues provide lipophilic anchoring. the resulting protein film reduces tewl and surface friction while providing amino acid nutrients.

Typically Found In: Hair conditioners,skin serums,protein formulas
