Isostearyl Isostearate 1 kg

Why Formulators Reach for This Ultra-Light Ester

Isostearyl isostearate is a synthetic ester valued across the personal care industry for its exceptionally light, silky glide and non-greasy after-feel. It belongs to the broad category of emollients for cosmetics, ingredients that soften skin texture, aid product spreadability, and contribute to pleasant sensory profiles in finished formulations. The 1 kg pack size is aimed at small to mid-scale cosmetic manufacturers, contract labs, and product development studios that need a reliable, repeatable supply for ongoing batch production of creams and color cosmetics.

The most common industrial applications of isostearyl isostearate include facial and body creams, lotions, lip balms, sunscreens, antiperspirants and deodorants, along with color cosmetics such as lipsticks, foundations, and concealers. Because of its molecular structure, the ester delivers a slip-rich but non-oily skin feel, speeds up absorption, and reduces the tacky residue often left behind by heavier vegetable oils. In sun care formulas it helps distribute UV filters evenly across the skin, while in decorative cosmetics it improves pigment dispersion and gives lipsticks a smoother, more pliable texture.

This ester blends well with other lightweight emollients and silicone alternatives. Paired with Softy Touch, it enhances a velvety, silk-like finish on skin, a combination frequently used in premium cream and serum development. It also works effectively alongside squalane, creating a light yet nourishing oil phase for hydrating products without any heavy after-feel. Combining it with Myristyl Lactate further improves emulsion stability and adds an extra softening effect on skin.

Isostearyl isostearate is typically introduced during the oil phase formation, usually at 60-75 degrees Celsius, alongside other lipid ingredients before homogenizing with the water phase. Recommended usage levels in finished formulations range from 3 to 15 percent of total product weight, depending on desired texture and product type: lighter lotions call for the lower end of the range, while lipsticks and dense balms require the higher end. The ingredient is thermally stable and compatible with most common cosmetic components, including emulsifiers, thickeners, and active additives. Store the raw material in a tightly sealed container, in a dry location at room temperature, away from direct sunlight and heat sources.

Weightless Facial Serum Base

Isostearyl isostearate 40 g

Squalane 30 g

Myristyl Lactate 15 g

Cetearyl alcohol 25 g

Distilled water 870 g

Glycerin 20 g

Heat the water phase with glycerin to 75 degrees, and separately melt cetearyl alcohol with isostearyl isostearate and squalane at the same temperature. Combine the oil phase into the water phase while stirring continuously, homogenize until uniform, then cool to 40 degrees before adding Myristyl Lactate and mixing until the batch reaches room temperature.
