Cosmetic Grade Isostearyl Alcohol-CAS 27458-93-1
Cosmetic Grade Isostearyl Alcohol is a high-purity branched-chain saturated fatty alcohol refined by professional hydrogenation purification and multi-stage precise fractionation technology.
As a premium multi-functional cosmetic emollient and stabilizer, it overcomes the solidification defect of linear C18 fatty alcohol, with permanent liquid state and excellent ultra-low temperature fluidity.
It balances moisturizing performance and refreshing skin feeling, providing soft and smooth application experience without greasiness. It has excellent solubilizing and emulsifying auxiliary capabilities, which can significantly improve the low-temperature resistance and system stability of cosmetic emulsions, effectively solving the problems of easy solidification, delamination and poor low-temperature stability of traditional formulas.
It can moisturize and repair skin, improve hair texture, and stabilize various oil-soluble functional ingredients. With mild formula performance, wide raw material compatibility and long-term stability, it is the preferred core raw material for all-season high-stability skin care and hair care products.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Isostearyl Alcohol?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and efficacy trial production.
• Q2: What certification documents can be provided?
A2: Complete COA, MSDS, heavy metal and microbial test reports and full set of customs clearance documents are available to support export declaration and cosmetic product filing.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Moisturizing cream & lotion: 3%–8%; Hair care products: 2%–5%; Sunscreen products: 4%–10%; Sensitive skin formulas: 2%–6%; Low-temperature resistant formulas: 5%–12%, adjustable according to product texture and stability requirements.
• Q4: What is the difference between Isostearyl Alcohol and Stearyl Alcohol?
A4: Stearyl alcohol is linear and easy to solidify at low temperature, with poor fluidity. Isostearyl alcohol is branched C18 alcohol, liquid at low temperature with excellent fluidity, better low-temperature stability and formula compatibility, more suitable for all-season and low-temperature resistant cosmetic formulas.
• Q5: Is Isostearyl Alcohol suitable for sensitive skin formulas?
A5: Yes. It is highly purified, mild and non-irritating, has excellent moisturizing and soothing effects, no pore clogging or sensitization risk, perfectly suitable for sensitive skin and dry skin care systems.
• Q6: What are the formula matching notes?
A6: It is oil-phase liquid raw material, recommended to add at 50-80℃ oil phase; compatible with most emulsifiers, esters and greases; can compound with behenyl alcohol to balance texture and low-temperature stability of cream products.
• Q7: Do you support stable large-batch supply all year round?
A7: Standardized hydrogenation and fractionation production lines ensure stable batch purity, viscosity and low-temperature resistance indicators, consistent product quality, sufficient inventory all year round, supporting long-term cooperative orders and customized formula matching services.
