Ethylhexylglycerin
EWG Risk Score:
1
What is it?
Ethylhexylglycerin is a conditioning agent and preservative.
Why is it a risk?
Two studies have found it to be a skin irritant, even at low concentrations, so people with sensitive skin may experience contact dermatitis. In addition, it is an eye irritant in animal studies. Reactions are typically low, however.
What Type of Products is it in?
Lotions, washes, shampoo, conditioner
Companies that use this ingredient:

Opinion:
Ethylhexylglycerin is a relatively new chemical on the market. Many companies use it as an alternative to parabens and claim that it's from natural sources. Yes, it may have started out as a vegetable oil, but it's gone through several chemical processes to become what it is. This isn't the worst ingredient in the world, but it's also not truly natural, and safety data is highly lacking for this ingredient. There are only four studies or reviews published in the National Library of Medicine.
Yes, manganese stearate is an ionic compound. It consists of manganese cations and stearate anions held together by ionic bonds.
The chemical symbol for sodium is Na, while the chemical formula for stearate is C18H35O2-. Therefore, the chemical symbol for sodium stearate is NaC18H35O2.
The molecular size of aluminum stearate can vary depending on its structure and the number of aluminum and stearate units present in the molecule. It is a salt formed by the reaction of stearic acid and aluminum hydroxide, typically resulting in a larger molecular size compared to the individual components.
To remove sodium chloride from calcium stearate, you can dissolve the mixture in water. Sodium chloride is water-soluble, so it will dissolve in the water while calcium stearate remains insoluble. By filtering the solution, you can separate the sodium chloride from the calcium stearate.
The ratio of Ca2+ ions to stearate anions depends on the specific compound or salt being referred to. For example, in calcium stearate (Ca(C17H35COO)2), the ratio is 1:2, with one Ca2+ ion for every two stearate anions. However, in other compounds, such as calcium di(stearate) (Ca(C17H35COO)2), the ratio may vary.
yes
The usual way would be from the corresponding alcohol.
The reaction between magnesium ions and sodium stearate would involve the magnesium ion (Mg^2+) displacing sodium (Na^+) in sodium stearate to form magnesium stearate and sodium ions. The equation can be represented as Mg^2+ + 2(C_17H_35COO^−) → Mg(C_17H_35COO)_2 + 2Na^+.
Glyceryl stearate is a covalent compound. It is formed by the sharing of electrons between the atoms in the molecule.
Because 'sdoium stearate' is the conjugate base of the weak carboxylic acid 'stearic acid'. Since a solution of stearic acid would be slightly acidic, a solution of sodium stearate will be basic or alkaline.
A poly oxo aluminum stearate contains synthetic enamel. The formula is 70 percent soya, 20 percent MTO, and 10 percent water.
