Description
Etocrilene, also known as Ethyl 2-Cyano-3,3-diphenylacrylate, is an organic ester that appears as an off-white crystalline powder. It functions as a UV absorber, effectively absorbing ultraviolet (UV) rays when applied to the skin. This property makes it a valuable ingredient in the formulation of various personal care and cosmetic products.
Uses
Used in Sun Protection Products:
Etocrilene is used as a UV absorber for sun protection products to shield the skin from harmful UV rays. Its ability to absorb UV radiation helps prevent sunburn and reduces the risk of skin damage and premature aging caused by excessive sun exposure.
Used in Cosmetics and Personal Care Products:
Etocrilene is used as a preservative in cosmetics and personal care products to protect them from deterioration. By incorporating Etocrilene into these products, manufacturers can extend their shelf life and maintain their efficacy over time.
Used in Bath, Skin, Cleansing, Hair, Nail, and Fragrance Products:
Etocrilene is used as a UV absorber in a wide range of personal care products, including bath, skin, cleansing, hair, nail, and fragrance products. Its inclusion in these products helps protect the user's skin and hair from the damaging effects of UV radiation, ensuring that the products remain effective and safe for use.

Check Digit Verification of cas no
The CAS Registry Mumber 5232-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5232-99:
(6*5)+(5*2)+(4*3)+(3*2)+(2*9)+(1*9)=85
85 % 10 = 5
So 5232-99-5 is a valid CAS Registry Number.

Investigation of the sunscreen octocrylene's interaction with amino acid analogs in the presence of UV radiation
Karlsson, Isabella,Persson, Elin,M?rtensson, Jerker,B?rje, Anna
, p. 904 - 912 (2012)
Octocrylene is an organic UV filter, commonly used in sunscreens and cosmetics, which can give rise to both contact and photocontact allergy. Our aim was to investigate octocrylene's interaction with amino acid analogs in the presence of UV radiation to b
Preparation method of cyanoacrylate ultraviolet light absorber

Paragraph 0093-0094; 0099-0104, (2020/04/29)
The invention provides a preparation method of a cyanoacrylate ultraviolet light absorber. Benzophenone compounds represented by general formula I with cyanoacetate under a weakly alkaline condition by using activated carbon grafted acidic ionic liquid as a catalyst to generate a compound represented by general formula II. The preparation method of the cyanoacrylate ultraviolet light absorber adopts the activated carbon grafted acidic ionic liquid catalyst to replace acetic acid, so that the preparation method has the advantages of easiness in recycling of the catalyst, high product yield, fewthree wastes, and convenience in post-treatment, and is an economical, practical and environment-friendly technology.
Synthesis of coumarins via PIDA/I2-mediated oxidative cyclization of substituted phenylacrylic acids

, p. 4311 - 4320 (2013/04/24)
A variety of functionalized coumarins were synthesized from substituted phenylacrylic acids via PIDA/I2-mediated and irradiation-promoted oxidative carbon-oxygen bond formation. Our studies show that the oxygen in the pendant carboxylic acid group cyclizes favorably to the aryl ring that is cis to it. The main advantages of this method include good functional group tolerance and the transition-metal-free characteristic. The Royal Society of Chemistry 2013.
