What are other names for Hydrolyzed Jojoba Esters?

HYDROLYZED JOJOBA ESTERS

What is Hydrolyzed Jojoba Esters used for?

Hydrolyzed jojoba esters can extend the moisturizing properties of traditional emulsions, and work as a refatting agent in astringents and toners. The high pH of Hydrolyzed jojoba esters make them suitable as a gel neutralizer to thicken carbomer gels.

General safety info about Hydrolyzed Jojoba Esters from CIR

Several cosmetic ingriedients derive from the desert shrub Simmondsia chinensis, including Simmondsia Chinensis (Jojoba) Seed Oil, Simmondsia Chinensis (Jojoba) Seed, and Simmondsia Chinensis (Jojoba) Butter. Further processing produces other ingredients including Hydrogenated Jojoba Oil, Hydrolyzed Jojoba Esters, Isomerized Jojoba Oil, Jojoba Esters, and Jojoba Alcohol. Synthetic Jojoba Oil also is used in cosmetics. In this group Simmondsia Chinensis (Jojoba) Seed Oil, the most widely used ingredient, and safe at concentrations up to 100% in body and hand creams, is expressed from seeds and is composed almost completely (97%) of wax esters of monounsaturated, straight-chain fatty acids and alcohols with high-molecular weights. Amounts and composition of the expressed oil varies with maturity of the seeds and somewhat with plant location and climate. Plant derived material may also contain pesticide residues and/or heavy metals. Most available safety test data examined the expressed oil. For example Simmondsia Chinensis (Jojoba) Seed Oil was reported to readily penetrate nude mouse skin and to increase penetration of other agents such as aminophylline in clinical tests. Simmondsia Chinensis (Jojoba) Seed Oil was not an acute oral toxicant to mice or rats (LD50 generally greater than 5.0 g/kg). Short-term subcutaneous administration of Simmondsia Chinensis (Jojoba) Seed Wax to rats at 1 ml/kg was not toxic. Neither the wax nor the oil were toxic when applied dermally to the shaved backs of guinea pigs in short-term tests. A dermal irritation test found aqueous Hydrolyzed Jojoba Esters (20%) to be non-irritating to guinea pigs. Jojoba Alcohol was found to be nonirritating to the skin of albino marmots at 10.0%. Simmondisa Chinensis (Jojoba) Butter was classified as a non-irritant when applied to the intact and abraded skin of New Zealand white rabbits at 0.5 ml for 24 h under an occluded patch. Jojoba Alcohol at concentrations up to 50% was minimally irritating in rabbits. Simmondsia Chinensis (Jojoba) Seed Oil was non- to slightly irritating when instilled into the eyes of white rabbits, but Simmondsia Chinensis (Jojoba) Seed Wax, Jojoba Esters, and Jojoba Alcohol were not. Simmondsia Chinensis (Jojoba) Seed Wax was moderately comedogenic in tests using rabbits, but Jojoba Esters was noncomedogenic, and Jojoba Esters were non- to slightly- comedogenic. Simmondsia Chinensis (Jojoba) Butter, Jojoba Alcohol, and Jojoba Esters were non-mutagenic in Ames testing. No carcinogenicity and no reproductive or developmental toxicity data were available. In clinical tests, Simmondsia Chinensis (Jojoba) Seed Oil was neither a significant dermal irritant, nor a sensitizer. In repeat insult patch tests Jojoba Alcohol , Jojoba Esters and Hydrolyzed Jojoba Esters were not irritating during induction or sensitizing at challenge. Simmondsia Chinensis (Jojoba) Seed Oil and Jojoba Alcohol were not phototoxic. The available safety test data were combined with the expected uses of these ingredients, which includes use in aerosolized products. Because the particle size of aerosol hair sprays (-38 µm) and pump hair sprays (>80 µm) is large compared to respirable particulate sizes (#10 µm), the ingredient particle size is cosmetic aerosols is not respirable. Relevant information also included uses with baby and eye products at low concentrations, and at 100% in hand and body creams. There were no structural alerts for the fatty acids, fatty alcohols, or other structures that would be found in these ingredients relative to reproductive/developmental toxicity, and these ingredients are not expected to easily penetrate skin. None of the tested ingredients were genotoxic and there were no structural alerts for carcinogenicity. The cosmetic industry should continue to limit pesticide and heavy metal impurities in the plant-derived ingredients before blending into cosmetic formulations. The CIR Expert Panel recognizes the gaps in use and use concentration data of these ingredients. Generally, the information available on the product types that include these ingredients and at what concentrations indicate a pattern to the Expert Panel when it assessed ingredient safety. Were unused ingredients used in the future, use is expected in comparable product categories and concentrations.
