High-Performance Sorbitan Isostearate Emulsifier CAS NO 71902-01-7 Sorbitan isostearate is an amber liquid emulsifier designed for water-in-oil (W/O) formulas.It is known for its excellent pigment dispersion and strong tolerance to polar oils, and is widely used in high-performance cosmetics such as sunscreens and foundations.Its HLB value is about 4.7, which can ensure the stability of the emulsion and the smooth texture of the product.
Superior Pigment Dispersion
This kind of emulsifier can evenly disperse inorganic pigments such as titanium dioxide and zinc oxide, prevent agglomeration and improve hiding power.It enhances the uniformity of the product and gives it a delicate texture, so it is ideal for sunscreen formulas and high-hiding makeup.Which means that you can easily solve the problem of pigment agglomeration and get a product with exquisite texture.
Reliable Formulation Stability
Sorbitan isostearate has excellent compatibility with a variety of oils, and can maintain emulsion stability even in systems containing polar oils.This stability ensures long-term consistent product performance, especially when combined with oils such as
Hydrogenated castor oil, which can further strengthen the anti-stratification ability of the system. It is a key advantage for cosmetic raw material suppliers who develop high-end formulas.You can rely on it to always maintain stable performance in complex formulas and reduce quality problems caused by system fluctuations.
Security
This ingredient has been included by INCI and included in the Chinese IECIC, which meets the global cosmetics safety standards.Under the recommended addition amount (0.5–5%), there is no risk of irritation or sensitization, and it is suitable for disposable and wash-off products.When used in combination with isothermal and surfactants such as
Coco glucoside (coconut oil-based glucoside), the skin-friendly properties of the formula can be further enhanced.You will get a safe and efficient emulsified raw material that provides a strong guarantee for product compliance.
