Caprylyl glycol is a preservative and skin-conditioning ingredient derived from coconut oil. It helps prevent bacterial and mold growth in skincare products while also providing mild hydrating and humectant benefits to the skin.
Benefits
Helps preserve product freshness and prevent contamination
Provides gentle humectant properties to help retain skin moisture
Often used as a gentler alternative to traditional preservatives
Potential concerns
Rare cases of allergic contact dermatitis have been reported in sensitive individuals
May cause irritation in those with known sensitivity to glycols
Science: A 200-subject repeat patch test study found no delayed hypersensitivity reactions to caprylyl glycol at typical use concentrations. However, isolated case reports of allergic contact dermatitis exist, suggesting it can act as an allergen in susceptible individuals. It is widely used in infant and sensitive-skin formulations as a preservative alternative.
Neopentyl Glycol Diheptanoate is a synthetic emollient and skin-conditioning agent that helps soften and smooth the skin. It's an ester made from neopentyl glycol and heptanoic acid, commonly used in cosmetics to improve texture and spreadability of formulations.
Benefits
Softens and conditions skin
Improves product texture and ease of application
Lightweight emollient that doesn't feel greasy
Science: Research demonstrates that Neopentyl Glycol Diheptanoate can be synthesized through enzymatic pathways with high purity (95% conversion) without additional purification steps, supporting its safety profile for cosmetic use. Limited peer-reviewed safety or efficacy data specifically addressing this ingredient's performance on human skin.
Dimethyl isosorbide is a clear liquid solvent derived from sorbitol that helps dissolve and deliver other skincare actives into the skin more effectively. It works by enhancing the penetration of beneficial ingredients and improving product texture and stability.
Benefits
Enhances penetration of active ingredients into skin
Improves product stability and shelf life
Lightweight solvent that feels comfortable on skin
Potential concerns
Can cause irritation or sensitization in sensitive skin at high concentrations
May increase skin penetration of other ingredients, which could be problematic if combined with irritating actives
Science: Dimethyl isosorbide is recognized as a penetration enhancer in cosmetic formulations. Research shows it has relatively low solubility for certain actives (such as piroctone olamine at 9.9 mg/mL), making it suitable for specific formulation strategies targeting epidermal delivery, though peer-reviewed safety and efficacy data in skincare is limited.
Isododecane is a lightweight, colorless liquid hydrocarbon used as a solvent and carrier in skincare formulations. It helps dissolve and deliver other active ingredients, particularly oil-soluble compounds like UV filters and silicone polymers, while providing a smooth, non-greasy feel on the skin.
Benefits
Serves as an effective solvent for oil-soluble actives and UV absorbers
Enables efficient delivery of ingredients into the skin
Provides a light, non-occlusive texture in formulations
Science: Research demonstrates that isododecane is a suitable solvent for UV-absorbing sunscreen ingredients and supports effective topical delivery of active compounds through the skin. It is commonly used in pharmaceutical and cosmetic formulations without documented safety concerns at typical use levels.
Camelina sativa seed oil is a plant-based oil extracted from camelina seeds, rich in omega-3 and omega-6 fatty acids. It's used in skincare products to moisturize and nourish the skin, helping to maintain the skin barrier and reduce dryness.
Benefits
Moisturizes and hydrates skin
Rich in fatty acids and antioxidants
May help soothe irritated or sensitive skin
Potential concerns
Potential allergic reactions in those with seed oil sensitivities
May cause breakouts in acne-prone individuals
Science: Limited peer-reviewed data available for this ingredient in cosmetic applications. General knowledge of plant oils suggests camelina's fatty acid profile supports skin barrier function, but specific efficacy and safety studies in skincare formulations are sparse.
