Oleic Acid

The Basics On Oleic Acid

What is Oleic Acid?

Oleic acid is a natural, monounsaturated omega-9 fatty acid that’s found in many plants.

What are other names for Oleic Acid?

9-OCTADECENOIC ACID, 9-OCTADECENOIC ACID (9Z)-, 9OCTADECENOIC ACID (Z), and OLEIC ACID

What is Oleic Acid used for?

Oleic acid is a godsend for dry, aging skin since it penetrates easily and deeply into the skin’s surface, replenishing lost moisture that naturally comes with age. It also helps the moisture from evaporating. Remember: Without oil, your skin becomes dry, meaning it becomes that much more vulnerable to fine lines, wrinkles, sagging and losing its bounciness. Oleic acid can restore this oil‚Äîwithout clogging pores. Oleic acid comprises antioxidant compounds that help fight free radical damage caused by environmental aggressors like UV rays, the top trigger of premature aging. By minimizing free radicals in skin, so too is the manifestation of wrinkles, fine lines, dark spots, sagging and other unwanted features.As an anti-inflammatory substance that stimulates wound healing, oleic acid can also help calm, balance and help repair skin, even those with damaged conditions like eczema, rosacea and psoriasis. Oleic acid also contains compounds that reinforce the integrity of cell membranes.

Oleic Acid During Pregnancy

What we know about using Oleic Acid while pregnant or breastfeeding

Limited information available.

Dermal and oral DART studies of several fatty acid and fatty acid salt ingredients are summarized in Table 13. Lithium Stearate caused no treatment-related adverse reproductive or developmental effects at doses up to 1000 mg/kg bw/day in dermal studies where male rats were treated for 43 days and female rats were treated for 33 days until gestation day 19. 28 While non-reproductive effects were noted in parental animals in a few oral studies, no treatment-related adverse effects were observed on the reproductive cycles or development of offspring in rats exposed to Behenic Acid (up to 1000 mg/kg/day; males were treated 42 days and females were treated ~39 days until lactation day 3), 22 Calcium Stearate (up to 1000 mg/kg/day; males were treated 28 days and females were treated ~39 days until lactation day 3), 35 Capric Acid (up to 2000 mg/kg/day; females were treated up to ~33 days until lactation day 4), 23 Caprylic Acid (up to 1000 mg/kg/day; females were treated for up to 9 days during gestation starting on gestation day 12), 25,60 or Undecylenic Acid (up to 1000 mg/kg/day; males were treated up to 28 days and females were treated up to 40 days until lactation day 4). 32 Lauric Acid, Myristic Acid, Oleic Acid, Palmitic Acid, Stearic Acid Although placental transfer of fatty acids has been documented in several species and fetal lipid metabolism has been studied, no studies on the teratogenicity of Oleic, Lauric, Palmitic, Myristic, or Stearic Acids were found.8 Feeding of 15% dietary Oleic Acid to rats in a chronic study resulted in impairment in the reproductive capacity of female rats. Little or no toxicity to sperm cells in vitro in whole semen samples by serial dilutions of Oleic Acid, Palmitic Acid, and Stearic Acid were observed in studies of these ingredients.9 Magnesium Stearate When fed to female rabbits at 8 days post-coitus, a pharmaceutical vehicle containing 5.5% by weight Magnesium Stearate was not teratogenic.4 Hydroxystearic Acid The dermal teratogenicity of two antiperspirant prototype formulations containing 7% Hydroxystearic Acid was evaluated using 2 groups of 30 Charles River Crl:CD VAF/Plus female rats on gestation days 6 through 15. 5 There were no test article-related or statistically significant differences in the incidence of fetal malformations or fetal developmental variations between experimental and control groups. Skin irritation reactions, however, were observed in greater than 50% of the dams in both experimental groups. No deaths were reported during the study.

General safety info about Oleic Acid from CIR

The Cosmetic Ingredient Review (CIR) Expert Panel assessed the safety of 102 fatty acids and fatty acid salts, most of which are reported to function as anticaking agents, emulsion stabilizers, viscosity increasing agents, opacifying agents, and surfactants in cosmetic products. The Panel reviewed the available data to determine the safety of these ingredients, noting that these ingredients may cause dermal irritation. Further, the Panel also noted the potential for polyunsaturated fatty acids to undergo oxidation during the formulation of cosmetic products, which may produce compounds that may be dermal sensitizers. The Panel concluded that fatty acids and fatty acid salts are safe in cosmetics in the present practices of use and concentration described in this safety assessment when formulated to be non-irritating and non-sensitizing, which may be determined based on a quantitative risk assessment (QRA).
