Sorbitan Sesquioleate

According to truthinaging.com,
“Sorbitan Sesquioleate is used in a variety of products including skin care products, skin cleansing products, moisturizers, eye makeup and other makeup, primarily as an emollient. It is added to formulas as a skin soother and moisturizer and is derived from sorbitol, a humectant. Little information is available regarding Sorbitan Sesquioleate’s exact role or differentiating characteristics from other sorbitan esters (RealSelf.com and Cosmetics Database).
Sorbitan Sesquioleate is considered a low hazard ingredient by the Cosmetics Database, which only notes mild concerns regarding organ system and toxicity, due to animal studies that showed organ effects and skin moderation at moderate doses.
Although the Sorbitan esters, including Sorbitan Sesquioleate, are generally mild skin irritants but nonsensitizers, a study published in Dermatitis entitled “Sorbitan Sesquioleate, a Common Emulsifier in Topical Corticosteroids, Is an Important Contact Allergen” found that although Sorbitan Sesqiuoleate has been considered an uncommon allergen in the past, it is causing reactions in more patients than expected. In a test of 112 patients, ten had allergic reactions to this ingredient. Ultimately, the study concluded that Sorbitan Sesquioleate may be sensitizing when applied to dermatitic skin.”
