Summary
Ricinus Communis (Castor) Seed Oil and related ricinoleate ingredients are safe for cosmetic use. The Expert Panel for Cosmetic Ingredient Safety confirmed their safety in various cosmetic applications.
Area of Science:
- Cosmetic Science
- Dermatology
- Toxicology
Background:
- Ricinus Communis (Castor) Seed Oil and its derivatives are common cosmetic ingredients.
- They function as skin-conditioning agents, emulsion stabilizers, and surfactants.
Purpose of the Study:
- To assess the safety of Ricinus Communis (Castor) Seed Oil and ricinoleate ingredients in cosmetic products.
- To review available animal and human data concerning these ingredients.
Main Methods:
- Safety assessment of cosmetic ingredients.
- Review of relevant animal and human data.
- Evaluation by the Expert Panel for Cosmetic Ingredient Safety.
Main Results:
- The Expert Panel for Cosmetic Ingredient Safety reviewed extensive data.
- Specific ricinoleate ingredients evaluated include Ethyl Ricinoleate, Glycol Ricinoleate, Hydrogenated Castor Oil, Methyl Ricinoleate, Potassium Ricinoleate, Ricinoleic Acid, Ricinus Communis (Castor) Seed Oil, and Sodium Ricinoleate.
Conclusions:
- The Expert Panel concluded that the assessed castor oil and ricinoleate ingredients are safe for cosmetic use.
- Safety is confirmed within the described practices of use and concentrations in cosmetic formulations.

01:25Esters to Carboxylic Acids: Saponification
6.4K
Esters can be hydrolyzed to carboxylic acids under acidic or basic conditions. Base-promoted hydrolysis of esters is a nucleophilic acyl substitution reaction in which esters react with an aqueous base, followed by an acid to give carboxylic acids. This reaction is also known as saponification because it forms the basis for making soaps from fats.
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...
