Description
2-Ethylhexyl Palmitate is an ester derived from 2-ethylhexyl alcohol and palmitic acid, commonly used in the cosmetics and skincare industry. It is a colorless, odorless liquid with a slightly fatty odor, offering a 'dry-slip' feel similar to silicone-based ingredients. This ingredient is known for its ability to improve the texture, feel, and scent of skincare and cosmetic products, making it a versatile and valuable addition to various formulations.
Uses
Used in Cosmetics and Skincare Industry:
2-Ethylhexyl Palmitate is used as an emollient for moisturizing and softening the skin by reducing water loss from the top layers of the skin. It provides a non-occlusive, dry-slip, silky feel, making it an ideal organic replacement for silicones in cosmetic formulations.
2-Ethylhexyl Palmitate is used as a solvent to help other ingredients dissolve, increasing the efficacy of active ingredients in a formulation by enhancing their absorption through the skin.
2-Ethylhexyl Palmitate is used as a pigment wetting agent, improving the pigment or color distribution in makeup formulations, resulting in an even application of eyeshadow or foundation pigments.
2-Ethylhexyl Palmitate is used as a fragrance fixative, equalizing the volatile fragrance components and making them last longer and remain more stable on the skin.
Safety
The safety of the Palmitates has been assessed by the Cosmetic Ingredient Revies (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Ethylhexyl Palmitate, Cetyl Palmitate and Isopropyl Palmitate were safe as cosmetic ingredients. In 2001, the CIR Expert Panel considered available new data on Ethylhexyl, Cetyl and Isopropyl Palmitate and reaffirmed the above conclusion.https://cosmeticsinfo.org/ingredient/ethylhexyl-palmitate

Check Digit Verification of cas no
The CAS Registry Mumber 29806-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,8,0 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 29806-73:
(7*2)+(6*9)+(5*8)+(4*0)+(3*6)+(2*7)+(1*3)=143
143 % 10 = 3
So 29806-73-3 is a valid CAS Registry Number.

Carbocatalysis: N-doped reduced graphene oxide catalyzed esterification of fatty acids with long chain alcohols
Porwal, Jyoti,Karanwal, Neha,Kaul, Savita,Jain, Suman L.
, p. 1547 - 1553 (2016/02/19)
Nitrogen doped reduced graphene oxide (N-rGO), 5.8% N readily synthesized from the thermal annealing of graphene oxide (GO) in ammonium hydroxide at 453 K, was demonstrated to be a superior metal-free non-acidic carbo-catalyst for the esterification of fatty acids with different alcohols. The effect of various reaction parameters such as reaction temperature, reaction time, catalyst amount etc. has been studied. The developed catalyst was found to be highly stable and exhibited consistent reusability for seven cycles without any significant decrease in the product yields.
Catalytic synthesis of the iso-octyl palmitate from palmitic acid and isooctanol with water-tolerant solid acid

body text, p. 4109 - 4113 (2012/01/19)
Iso-octyl palmitate is synthesized via esterification of palmitic acid and isooctanol when the water-tolerant solid acid is used as the catalyst. The particular chelate molecular structure of SnC2O4 makes Sn atom have the suitable acid intensity. The steric hindrance in the course of the reaction is reduced because of its molecular structure with the plane surface. In addition, the stability of molecule of SnC2O4 is strengthened because of its chelate molecular structure. All these factors lead to its high catalytic activity in the esterification reaction. Many factors, which have an effect on the yield of iso-octyl palmitate, have been studied. The reaction conditions for synthesizing isooctyl palmitate with high yield are optimized with the orthogonal experiment. The optimum conditions for synthesizing iso-octyl palmitate with high yield are as follows: reaction time is 2.5 h and the mol ratio of isooctanol to palmitic acid is 1.8:1 and the dosage of the catalyst is 2.0 % and the reaction temperature is 150°C.
