Ingredients Details & Usage Documents Isopropyl Lauroyl Sarcosinate (IPLS) Highly polar specialty emollient and solubilizing carrier for ceramides, functional lipids, difficult oil-soluble ingredients, UV-filter systems and pigment dispersions. INCI Name: Isopropyl Lauroyl Sarcosinate CAS Number: 230309-38-3 Appearance: Clear to pale yellow liquid Solubility: Oil soluble; compatible with a broad range of cosmetic emollients and oil-phase ingredients Function: Highly polar emollient, solubilizing carrier, pigment wetting and dispersing aid, oil-phase formulation aid and sensory modifier Isopropyl Lauroyl Sarcosinate is an naturally derived amino-acid based, highly polar liquid emollient valued for its combination of strong oil-phase solvency and exceptionally lightweight sensory performance. Its polarity makes it especially useful for materials that can be difficult to incorporate into conventional cosmetic oils and esters. IPLS is particularly valuable in advanced formulations containing ceramides, cholesterol, functional lipids, difficult oil-soluble ingredients, organic UV-filter systems, pigments and mineral particles. At the same time, its low viscosity and excellent spreadability contribute a smooth, silky and non-greasy finish. Highly Polar Emollient Ceramide Solvent Functional Lipid Solvent Oil-Phase Solubilizer UV Filter Solvent Pigment Dispersing Aid Lightweight Skin Feel Advanced Formulation Aid Supplied as a cosmetic raw material for professional formulation use. Performance & Formulation High Polarity for Difficult Oil-Phase Ingredients The defining characteristic of IPLS is its high polarity. This gives it stronger solvency for certain poorly soluble lipophilic materials than many conventional cosmetic oils and esters, while maintaining the elegant sensory characteristics of a lightweight emollient. This combination makes IPLS especially useful in ceramide concentrates, barrier-lipid systems, sun care, pigment dispersions and technically demanding oil-phase formulations. Ceramides & Barrier Lipids Ceramides can be challenging to formulate because of their crystalline structure and limited solubility in many conventional cosmetic oils. IPLS provides a highly polar oil-phase environment that can help improve their incorporation into properly designed carrier systems. Technical testing on Isopropyl Lauroyl Sarcosinate has demonstrated strong solubilizing performance with ceramide mixtures compared with conventional carriers such as Caprylic/Capric Triglyceride, Isopropyl Myristate and liquid paraffin. This makes IPLS particularly useful for: Ceramide concentrates Multi-ceramide systems Ceramide + cholesterol blends Barrier-lipid concentrates Barrier-support serums and emulsions Specialty lipid-phase systems Cholesterol & Functional Lipids The solvent performance of IPLS extends beyond ceramides. Technical comparative testing has also demonstrated strong solubilizing ability with cholesterol and gamma-oryzanol, making IPLS particularly interesting for complex lipid systems where several functional materials must coexist within the same oil phase. This can be valuable in barrier-focused formulations, lipid concentrates and other advanced skincare systems where ordinary cosmetic oils provide insufficient solvency. Sun Care & UV-Filter Systems IPLS is particularly useful in sun-care formulations because many organic UV filters can be difficult to fully dissolve and maintain in solution. Its high polarity can provide strong oil-phase solvent performance while maintaining a lightweight, elegant sensory profile. It can be evaluated as part of the solvent system for crystalline or poorly soluble oil-soluble UV filters, helping support efficient incorporation and reduce the risk of crystallization within properly designed formulations. In mineral and hybrid sun-care systems, IPLS can also support the wetting and dispersion of titanium dioxide, pigments and other oil-dispersible particles. UV-filter selection and permitted use levels depend on the regulations of the intended market. Pigment & Powder Dispersion IPLS has strong wetting properties and affinity for pigments, making it useful as a dispersing aid in color cosmetics and mineral systems. Efficient wetting can help improve pigment distribution, application uniformity and the overall quality of the finished dispersion. It is particularly useful in: Foundations and skin tints Concealers and primers Lip products Pigment concentrates Titanium dioxide dispersions Mineral and hybrid sun-care systems Makeup-skincare hybrid formulations Lightweight Sensory Performance Despite its strong solvency, IPLS remains a low-viscosity emollient with excellent spreading characteristics. It provides a light, smooth, non-greasy and non-sticky finish, allowing formulators to improve oil-phase performance without necessarily creating a heavier finished product. It can help improve glide and application while refining the feel of richer oils, functional lipid systems, pigment dispersions and concentrated sun-care oil phases. Key Benefits Highly polar specialty emollient with strong oil-phase solvency. Helps incorporate difficult lipophilic and functional lipid materials. Especially useful for ceramide and barrier-lipid systems. Demonstrated solubilizing performance with ceramides, cholesterol and gamma-oryzanol. Useful as part of solvent systems for difficult organic UV filters. Supports wetting and dispersion of pigments and mineral particles. Useful for titanium dioxide and color cosmetic dispersions. Provides excellent spreadability and glide. Helps reduce the heavy or greasy character of richer oil phases. Leaves a lightweight, smooth and non-sticky finish. Useful across skincare, sun care, makeup and haircare formulations. When IPLS Is Especially Useful When ceramides are difficult to incorporate into conventional oils When developing ceramide + cholesterol barrier systems When functional lipids crystallize or precipitate from conventional carriers When difficult oil-soluble ingredients require a more polar carrier When an organic UV-filter system requires stronger oil-phase solvency When pigments or mineral particles require improved wetting and dispersion When strong solvent performance is needed without a heavy sensory profile When developing concentrated specialty lipid or oil-phase systems Suggested Use Levels 2–5% — Emolliency, sensory enhancement, pigment wetting and general oil-phase support 5–10% — Ceramide systems, sun care, difficult oil-phase materials and stronger solvent functionality Specialized concentrates — Higher levels may be evaluated when IPLS is intentionally used as a major component of the carrier phase Ideal Applications Ceramide concentrates Multi-ceramide barrier systems Ceramide + cholesterol systems Functional lipid concentrates Barrier-support serums and creams Specialty oil-phase concentrates Facial serums and treatment oils Sun-care formulations Organic UV-filter systems Mineral and hybrid sun-care systems Foundations and skin tints Primers and concealers Lip products Pigment dispersions Lightweight moisturizers Anhydrous treatment systems Hair serums and finishing products Formulation & Processing Notes Incorporate into the oil or anhydrous phase. For difficult crystalline materials, combine with IPLS and use appropriate heat and mixing where required for dissolution. Ceramides and cholesterol may require elevated processing temperatures depending on grade and concentration. Confirm that difficult materials remain dissolved after the system has completely cooled. IPLS may be used as a specialty carrier or blended with other emollients to optimize solvency, sensory profile and formulation cost. Compatible with a broad range of commonly used cosmetic oil-phase materials. Can be combined with C12-15 Alkyl Benzoate, Caprylic/Capric Triglyceride, Squalane, Isoamyl Laurate and other emollients as part of a customized carrier system. For pigment systems, IPLS can be used to pre-wet pigments before dispersion or milling. For sun-care systems, confirm oil-phase clarity and stability after cooling and throughout stability testing. Evaluate compatibility and long-term stability within the complete finished formulation before scale-up. Important for Difficult-to-Solubilize Ingredients Complete dissolution while hot does not necessarily guarantee stability after cooling. When working with ceramides, cholesterol, functional lipids or other crystalline materials, evaluate the system after cooling and throughout stability testing to confirm that crystallization or precipitation does not occur.
