Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Skin dryness or tightness | Common | Soap-based surfactants derived from it can strip natural oils, especially with frequent use. |
| Skin irritation | Uncommon | May cause mild irritation in sensitive individuals or at higher concentrations. |
| Comedogenicity (pore clogging) | Uncommon | Considered moderately comedogenic; may contribute to breakouts in acne-prone skin. |
| Allergic contact dermatitis | Rare | Sensitization is infrequent but has been reported. |
| Mild skin irritation | Uncommon | Occasional transient redness or stinging, more likely in sensitive or compromised skin. |
| Comedogenicity / pore clogging | Uncommon | May contribute to clogged pores in acne-prone individuals depending on concentration and formulation. |
| Dryness or tightness | Common | Can disrupt the skin barrier and strip natural oils with frequent use. |
| Chemical burns | Rare | Occurs primarily with concentrated raw material or improper formulation, not in finished consumer products. |
| Eye irritation or injury | Uncommon | Risk with accidental contact, particularly with cleansers near the eye area. |

| Ingredient | What it does |
|---|---|
| Water Solvent/vehicle | Water is the most common base ingredient in cosmetic formulations, serving as a solvent that dissolves other ingredients and forms the bulk of emulsions and aqueous solutions. It is generally considered safe and non-irritating. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Myristic Acid Surfactant/cleansing agent | Myristic acid is a saturated fatty acid commonly used in skincare as a cleansing and emulsifying agent, often reacted with alkalis to form soap-based surfactants. It contributes to foaming and texture in cleansers and other formulations. |
| Stearic Acid Emulsifier / thickener | Stearic acid is a saturated long-chain fatty acid widely used in cosmetics as an emulsifier, thickening agent, and emollient to stabilize creams and lotions. It is generally considered a base/formulation ingredient rather than a therapeutic active. |
| Potassium Hydroxide pH adjuster / saponifying agent | Potassium hydroxide is a strong alkaline compound used in cosmetics to adjust pH and to saponify fatty acids in the production of liquid soaps and cleansers. At regulated low concentrations in finished products it is considered safe, functioning as a formulation aid rather than an active treatment. |
| Lauric Acid Cleansing/surfactant & emollient fatty acid | Lauric acid is a medium-chain saturated fatty acid commonly derived from coconut or palm kernel oil, used in skincare as a cleansing agent, emulsifier, and emollient. It also has documented antimicrobial activity, particularly against Cutibacterium acnes. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| Glycol Distearate Opacifier/pearlescent agent, emollient | Glycol Distearate is a diester of ethylene glycol and stearic acid used primarily to impart a pearlescent or opaque appearance to cleansers and shampoos, while also providing mild emollient and thickening properties. It functions as a formulation aid rather than an active treatment ingredient. |
| Polysorbate 80 Emulsifier / surfactant / solubilizer | Polysorbate 80 is a nonionic surfactant derived from sorbitol and oleic acid, used to emulsify oil and water phases and solubilize fragrances and oils in cosmetic and pharmaceutical formulations. It functions as a formulation aid rather than a therapeutic active. |
| Salix Alba (Willow) Bark Water Astringent/conditioning agent | Salix Alba (Willow) Bark Water is the aqueous extract of white willow bark, naturally containing salicin and tannins, used in skincare for mild astringent, soothing, and conditioning effects. It is often included as a gentle, plant-derived alternative source of salicylate compounds. |
| Sodium Methyl Cocoyl Taurate Mild surfactant/cleansing agent | Sodium Methyl Cocoyl Taurate is a gentle, taurine-derived anionic surfactant used in cleansers and shampoos to provide foaming and cleansing while being milder than sulfate-based surfactants. It is generally well tolerated and often chosen for sensitive-skin formulations. |
| Cocamidopropyl Betaine Surfactant / foaming cleanser | Cocamidopropyl Betaine is an amphoteric surfactant derived from coconut oil and dimethylaminopropylamine, used in cleansers, shampoos, and body washes to provide gentle foaming, viscosity, and to reduce the harshness of stronger anionic surfactants. It is widely regarded as mild but is a recognized contact allergen. |
| PEG-60 Hydrogenated Castor Oil Solubilizer/emulsifier | PEG-60 Hydrogenated Castor Oil is a nonionic surfactant derived from hydrogenated castor oil reacted with ethylene oxide, widely used to solubilize fragrances, oils, and lipophilic actives into water-based cosmetic formulations. It functions as a base/formulation aid rather than a treatment active. |
