| INCI | Glyceryl stearate citrate |
| Manufacture | Glyceryl stearate citrate is a combination of glycerin mono-/distearates and citric acid esters from mono- and diglycerides. Glyceryl stearate itself is made by reacting glycerin with stearic acid, a fatty acid obtained from soy oil. |
| Preservation | Preservative-free |
| Purity Grade | No purity grade applicable |
| Raw Material Source | Palm (Elaeis guineensis), rape/canola (Brassica), sugar cane (Saccharum officinale), sugar beet (Beta vulgaris) and/or corn (Zea mays) |
| Uses | Add pellets to the hot oil phase (approx. 80oC / 176oF) and stir until homogeneous. Combine then with hot water phase. Typical use level 1.5-2.5%. Stable emulsions from pH 5.5 - 8.0. For external use only. |
Glyceryl Stearate Citrate serves as a natural emulsifier for creating modern oil-in-water creams and lotions, derived entirely from vegetable raw materials. This anionic emulsifier is integral for formulating PEG-free, stable products, making it a safe choice, even for food applications. It is particularly effective in producing emulsions that align with the slightly acidic natural pH of human skin, making it ideal for sensitive skin formulations. Primarily utilized in concentrations ranging from 1.5% to 3.0%, Glyceryl Stearate Citrate aids in enhancing consistency and oil-binding capacity within skincare products.
What is Glyceryl Stearate Citrate, and what are its main components?
Glyceryl Stearate Citrate is a natural, edible emulsifier derived from a combination of glycerin mono-/distearates and citric acid esters from mono- and diglycerides. It is primarily used in modern oil-in-water creams and lotions.
What makes Glyceryl Stearate Citrate suitable for use in skincare products?
Glyceryl Stearate Citrate is based entirely on vegetable raw materials and is highly safe, making it particularly suitable for sensitive skin. Its role as an anionic emulsifier enables formulators to create PEG-free stable products, ensuring their safety and efficacy in skincare applications.
How does Glyceryl Stearate Citrate benefit formulations with an acidic pH value?
Glyceryl Stearate Citrate is well suited for making emulsions with a slightly acidic pH value, which corresponds to the natural pH value of human skin. This compatibility aids in maintaining the skin's natural balance and integrity.
In what concentrations is Glyceryl Stearate Citrate typically used in products?
Glyceryl Stearate Citrate is used in concentrations ranging from 1.5 to 3.0%. This concentration range allows it to effectively support the consistency and oil-binding capacity of skincare formulations without affecting safety or efficacy.
Is Glyceryl Stearate Citrate approved for consumption, and how is it regarded regarding safety?
Yes, Glyceryl Stearate Citrate is approved for use as an emulsifier in foods, underscoring its high safety profile. Its natural derivation and compatibility with sensitive skin further emphasize its suitability for a wide range of cosmetic and personal care applications.
