Isostearyl Isostearate Liquid – Premium Cosmetic Emollient for High-Performance Skincare Formulations

Our 60,000㎡ GMP manufacturing plant is equipped with sophisticated esterification technology to produce high purity fully saturated liquid ester of Isostearyl Isostearate. We have over 14 years experience in the creation of cosmetic raw materials. We supply this double branched emollient with a minimum purity of 99% and an annual production capacity of 3,000 tonnes along with strong quality control processes. Each batch is rigorously tested for GC purity, acid value, and peroxide value, guaranteeing consistent quality that conforms to worldwide cosmetic-grade standards for luxury skincare, colour cosmetics and barrier repair formulations.

What Makes This Premium Emollient Essential for Modern Cosmetics?

This specialised ester is the enhanced branched-chain technology of isostearyl alcohol and isostearic acid The molecular framework of C₃₆H₇₂O₂ gives outstanding oxidative stability, which is greater than that of traditional emollients.

This substance will address major formulation problems. It offers excellent occlusivity to decrease transepidermal water loss without leaving the greasy residue that mineral oils typically leave behind. It prevents pigment separation and provides elegant skin feel for colour cosmetics application.

It is a clear to yellowish translucent liquid with excellent low temperature stability (pour point between -15°C to -5°C). This branching architecture generates a semi-permeable coating that traps moisture, yet allows normal skin respiration – a tough balancing act to achieve with linear-chain alternatives.

Core Functional Benefits for Your Formulations

Superior Emollient Performance

The double branched molecular architecture fits well into the lipid bilayer of the stratum corneum. This replicates natural skin lipids, drastically lowering TEWL while providing the quality, non-greasy after-feel consumers expect from premium treatments.

Pigment Dispersion, Advanced

润肤剂与保湿剂的作用和区别| LM SKINCENTRE

Your colour cosmetic compositions are excellent in wetting properties. It reduces syneresis (pigment sweating) in lipsticks and provides uniform colour dispersion in high-pigment-load anhydrous systems, protecting product integrity throughout shelf life.

Enhancing the Stability of Formulation

The ingredient is resistant to rancidity and colour loss as shown by low iodine readings (<2.0 gI2/100g) indicating excellent oxidative stability. It is compatible with practically all W/O and O/W systems, which makes your formulation development easier.

High-Performance Application Scenarios

Premium Skincare Products

This emollient is found in advanced barrier repair creams and medical-grade moisturisers to help condition skin and aid recovery of impaired skin. The capacity to produce liquid-crystal with certain emulsifiers enhances the effect of barrier restoration.

Excellence in Colour Cosmetics

It serves as a specific pigment carrier for liquid foundations, lipsticks and BB creams. The high refractive index gives a glossy sheen and also retains the brightness of the colour. It gives a very smooth application without the sticky residue that you get with many high coverage formulas.

Sunscreen Tuning

It is an efficient solvent for organic UV filters such as Avobenzone and improves their solubility and photo-stability. Your SPF formulas distribute easily and evenly without leaving heavy films, especially in humid or high-temperature circumstances.

Hair Care Uses

In conditioning treatments and style products, Isostearyl Isostearate adds lubrication and shine improvement without weighing down hair strands or building up with repeated applications.

Quality Assurance and Compliance Standards

We manufacture under full-process quality control, under food-grade manufacturing conditions. Each batch is accompanied with complete documentation: COA, TDS, Allergen Statement, Non-GMO, and complies with Halal and Kosher regulations.

Testing protocols include all key parameters. Purity levels as verified by gas chromatography. Testing for acid value guarantees a low level of free fatty acids that might irritate skin or shift pH. The peroxide value monitoring during manufacture confirms no oxidative deterioration.

We are ISO and GMP certified and our expert QC team strictly inspects using advanced analytical instruments. Heavy metal screening and microbiological testing provide product safety for cosmetic uses across the world.

FAQ

Q: How does it differ from Isopropyl Myristate?

A: This ingredient has much better oxidation resistance and a reduced comedogenic potential, thus it is safer to use on the face for lengthy wear times where skin tolerance is a big concern.

Q: Will it work with natural or green formulations?

A: Yes, our product can be derived from 100% vegetable origin and is suitable for COSMOS or Ecocert standards depending on your certification requirements.

Q: Will it change the viscosity of O/W emulsion?

A: It delivers a natural bodying action which helps to improve the creamy texture without the drag of stearic acid or waxes, allowing you more control of the final product consistency.

Q: Compatible with silicone oils?

A: It is compatible with dimethicone and cyclomethicone and is widely used as a coupling agent between organic oils and silicones in hybrid formulations.

Q: And breathability of the skin?

A: The branching structure forms a semi-permeable layer with good occlusive efficiency for moisture retention, enabling normal skin respiration and solving the consumer worry about pore-clogging.
