◐ Handmade Soap (syndet and lotion bars)
☑ Cosmetics — three-line functional ingredient (same ingredient as the Glycerol Monostearate-SE document)
Glyceryl stearate SE is the self-emulsifying grade of glyceryl stearate: the plant-derived glycerin–stearic acid ester pre-blended with a small amount of potassium or sodium stearate (a soap) that supplies the water-loving component. That addition turns a co-emulsifier into a stand-alone oil-in-water emulsifier, so a single ingredient can build a rich, opaque, cushiony cream — the simplicity that makes it valuable for small-batch and Build-Your-Own formulation. It leaves a soft, skin-like film, because monoglycerides resemble the skin’s own lipids, and the Cosmetic Ingredient Review Panel has concluded glyceryl stearate SE is safe in cosmetics [1]. Its soap component makes it anionic and mildly alkaline, so it is destabilized by strong acids, high electrolytes, and cationic ingredients — the reason ORY® pairs acidic actives with the non-SE grade plus a non-ionic partner instead.
What is Glyceryl Stearate SE made of?
Glyceryl stearate SE is glyceryl monostearate co-processed with 3–8% potassium or sodium stearate. Points to know [1, 2]:
- Glyceryl stearate (~92–97%): Oil-loving emollient emulsifier; skin-mimetic monoglyceride.
- Potassium/sodium stearate (~3–8%): Anionic soap that provides the water-loving balance — “self-emulsifying.”
- Anionic character: Best at pH 6–8; destabilized by pH <5.5, high electrolytes, and cationics (BTMS).
- White waxy flakes; melts ~58–62 °C; vegan; palm-free grades available.
- Typical use: 3–8% for creams; 2–5% in haircare and cosmetics.
What skin type is best suited for Glyceryl Stearate SE?
Glyceryl stearate SE suits all seven ORY® skin types in neutral-pH creams:
- Dry: Rich, cushiony creams with a skin-like film.
- Sensitive: Non-irritating structural emulsifier; fragrance-free.
- Mature: Cushioning night and hand creams.
- Normal: Everyday cream base.
- Combination: Adjust level for lighter creams.
- Oily: Keep low; add lightweight esters (shea ethyl esters).
- Acne-prone: Low comedogenicity at use levels; light formulas.
What hair type is best suited for Glyceryl Stearate SE?
Glyceryl stearate SE thickens creamy, non-cationic haircare:
- Dry or damaged: Rich hair creams and masks (non-cationic).
- Curly and coily: Creamy leave-ins and curl creams.
- Straight and wavy: Light styling creams.
- Color-treated: Neutral; avoid with acidic color-sealing formulas.
- Oily scalp, sensitive scalp, dandruff-prone, mature or thinning: Structural; not combined with BTMS conditioners.
What are the benefits of Glyceryl Stearate SE?
Glyceryl stearate SE’s benefits are functional [1, 2]:
- Stand-alone O/W emulsifier: Builds creams without a second emulsifier.
- Rich, cushiony texture: Opaque, luxurious.
- Skin-like emollience: Monoglyceride film [2].
- Thickening: Body without gums.
- Simple formulation: Small-batch and custom creams.
- Gentle: CIR-reviewed [1].
- Pigment dispersion: Cream foundations and blush.
