This is a review of the scientific literature and unpublished data that are relevant for assessing the safety of 12 (sunflower)-derived ingredients as used in cosmetics. Because final product formulations may contain multiple botanicals, each containing similar constituents of concern, formulators are advised to be aware of these constituents and to avoid levels that may be hazardous to consumers. (sunflower)-derived ingredients may contain allergens, including 2S albumins and sesquiterpene lactones.

The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of 19 plant-derived proteins and peptides, which function mainly as skin and/or hair conditioning agents in personal care products. The Panel concluded that 18 plant-derived proteins and peptides are safe as used in the present practices of use and concentration as described in this safety assessment, while the data on Hydrolyzed Maple Sycamore Protein are insufficient to determine safety.

The Cosmetic Ingredient Review (CIR) is a nonprofit program to assess the safety of ingredients in personal care products in an open, unbiased, and expert manner. Cosmetic Ingredient Review was established in 1976 by the Personal Care Products Council (PCPC), with the support of the US Food and Drug Administration (USFDA) and the Consumer Federation of America (CFA). Cosmetic Ingredient Review remains the only scientific program in the world committed to the systematic, independent review of cosmetic ingredient safety in a public forum.

Formaldehyde and methylene glycol may be used safely in cosmetics if established limits are not exceeded and are safe for use in nail hardeners in the present practices of use and concentration, which include instructions to avoid skin contact. In hair-smoothing products, however, in the present practices of use and concentration, formaldehyde and methylene glycol are unsafe. Methylene glycol is continuously converted to formaldehyde, and vice versa, even at equilibrium, which can be easily shifted by heating, drying, and other conditions to increase the amount of formaldehyde.

Background: The toxicity of arsenic compounds is highly dependent on the valence and methylation state of the compound. Although there is extensive published literature on the potential developmental toxicity of inorganic arsenic compounds, little exists on organic arsenic compounds and, in particular, studies conducted in accordance with conventional regulatory guidelines appropriate for risk assessment are rare. The organic arsenic compounds, monomethylarsonic acid (MMAV) and dimethylarsinic acid (DMAV, also called cacodylic acid), are the active ingredients in pesticide products that are used mainly for weed control.
