118-56-9 Usage
Description
Homosalate, a homolog of menthyl salicylate, is a chemical UVB absorber that is used as a UV filter in various personal skin care formulations and cosmetics. It is a viscous or light yellow to slightly tan liquid or oil. Homosalate is included in the FDA’s Category I Sunscreen Chemical list and has an approved usage level of 4 to 15 percent by the FDA and 10 percent by the European Union’s Cosmetic Directive.
Uses
Used in Personal Skin Care and Cosmetics Industry:
Homosalate is used as a UV filter for protecting the skin from harmful UV radiation. It is incorporated into various personal skin care formulations and cosmetics to provide sun protection and prevent sunburn.
Used as a UV Screen:
Homosalate is used as a UV screen to absorb ultraviolet radiation and protect the skin from damage caused by the sun's rays.
Used as an Analgesic:
Homosalate has also been found to possess analgesic properties, making it useful for relieving pain and discomfort.
Brand Names:
Some of the brand names under which Homosalate is marketed include Eusolex (Rona Laboratories, Great Britain) and Heliophan (Greeff).
Air & Water Reactions
Homosalate will hydrolyze under basic conditions. . Insoluble in water.
Reactivity Profile
An ester and a phenol. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Fire Hazard
Homosalate is probably combustible.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 118-56-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118-56:
(5*1)+(4*1)+(3*8)+(2*5)+(1*6)=49
49 % 10 = 9
So 118-56-9 is a valid CAS Registry Number.

Synthetic method of homosalate
-
Paragraph 0023; 0024, (2016/11/21)
The invention provides a method for synthesizing homosalate through an ester exchange reaction of methyl salicylate or ethyl salicylate and 3,3,5-trimethylcyclohexanol under the catalysis of an alkali. The method has the advantages of simple operation, high conversion rate, economy, environmental protection, and suitableness for industrial production.

COSMETIC COMPOSITIONS COMPRISING AN ESTER DERIVED FROM 4-CARBOXY-2-PYRROLIDINONE AND A LIPOPHILIC SCREENING AGENT; USE OF SAID DERIVATIVE AS A SOLVENT FOR A BENZOPHENONE LIPOPHILIC SCREENING AGENT
-
, (2012/11/07)
The present invention relates to a composition comprising, in a cosmetically acceptable medium, at least one ester derived from 4-carboxy-2-pyrrolidinone, of formula (I) below: in which: R1 denotes a linear or branched C1-C20 alkyl radical,R2 denotes a linear or branched C1-C20 alkyl radical that may contain a C5-C6 ring, the phenyl radical, the benzyl radical or the phenethyl radical,and at least one benzophenone-type lipophilic UV screening agent. The present invention also relates to the use of at least one ester derived from 4-carboxy-2-pyrrolidinone, of formula (I), as defined above, in a composition comprising, in a cosmetically acceptable medium, at least one benzophenone-type lipophilic UV screening agent, as a solvent for said benzophenone screening agent, in and/or as an agent for improving the solubility of said benzophenone screening agent in said composition or with the aim of improving the sun protection factor.
