phenoxyethanol and ethylhexylglycerin. Phenoxyethanol is a high boiling point, low volatility solvent, and a hypoallergenic, efficient, broad-spectrum antiseptic and bactericide. Because it is soluble in both water and oil, phenoxyethanol has been used more and more in my country’s light industry and daily chemical fields in recent years.
Phenoxyethanol (CAS 122-99-6) belongs to aromatic ether alcohol, alias ethylene glycol monophenyl ether, phenyl cellosolve (2-Phenoxyethanol), molecular formula C8H10O2.
Phenoxyethanol is colorless and slightly viscous oily liquid, slightly fragrant, astringent, slightly soluble in water, basically insoluble in mineral oil, and can be mixed with acetone, ethanol and glycerin at will.
Finished products of phenoxyethanol may contain no more than 1% residual phenol or phenoxyethanol diethoxy compounds (risk analysis needs to be taken into account during development). Phenoxyethanol of cosmetic raw material grade is usually about 98% pure, and the ethylene oxide content is less than 1ppm.
As a widely used cosmetic preservative, many countries in the world have formulated strict management regulations on the use of phenoxyethanol. The European Union, Japan and my country all allow the use of phenoxyethanol, which stipulates that the maximum allowable dosage is 1%. The USFDA considers it safe for use in cosmetics. phenoxyethanol and ethylhexylglycerin.
Phenoxyethanol, or 2-phenoxyethanol, has broad antimicrobial activity and has been widely used as a preservative in cosmetics for decades. It is effective against various gram-negative and gram-positive bacteria and yeast, and has a weak inhibitory effect on the native flora of the skin. According to the European Scientific Committee on Consumer Safety, when phenoxyethanol is used as a preservative in cosmetic products at a maximum concentration of 1%, it is safe for all consumers, including children of all ages.
Adverse systemic effects have been observed in animal toxicology studies, but are likely to occur in consumers only when exposure levels are many orders of magnitude (about 200-fold higher) than those experienced with cosmetic products containing phenoxyethanol . According to individuals in the process of development and use, shampoo products with higher doses of phenoxyethanol may cause a certain itching feeling, and when used in some facial mask products, there may be fever (or spicy) Although it is widely used in cosmetics, phenoxyethanol is a rare sensitizer. It can be considered one of the most widely used preservatives in cosmetics, and is currently a relatively safe preservative within the prescribed dose range.
Ethylhexylglycerin is often used as a solvent or additive because of its moisturizing effect, antibacterial properties and strong stability, which can improve the moisturizing effect of the product and has a smooth skin feel. phenoxyethanol and ethylhexylglycerin.
The ingredient can also enhance traditional preservatives such as phenoxyethanol, methylisothiazolinone, methylparaben, etc., reduce the amount of these ingredients in the product, and increase the safety of the product.
Aliases: Caprylyloxyglycerin; Glycerol monoisocaprylyl ether
CAS No.: 70445-33-9
Molecular formula: C11H2403
Ethylhexylglycerin can synergize traditional preservatives to reduce the amount of these substances in cosmetics, and improve the antibacterial effect of multifunctional cosmetic additives such as glycols and fatty acid esters.
It can inhibit the unpleasant odor produced by the sebum and exfoliated epidermal cells in human sweat under the action of geriatric-positive bacteria. At the same time, it can improve the moisturizing effect of the formula and have a smooth skin feel, and solve the stickiness of some creams. And the shortcomings of skin feel such as whitening.

About the waxing process of candle machine
1. Follow wax: Add some water to the pot, put the solid paraffin into the pot (can melt the paraffin into wax water), melt it into liquid wax water until the pot is added to the configuration pigment color.
Soy Wax is a vegan wax made from the complete oiling of soybeans. Like honey, it is considered a natural wax, and 100% pure soy wax is often used in containers of soy wax.
Paraffin wax is a hydrocarbon mixture extracted from some distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and it is a white or light yellow translucent solid.
Paraffin is a purified mixture of solid saturated hydrocarbons. Paraffin wax is a flaky or needle-like crystal obtained from lubricating oil fractions obtained by distillation of crude oil through solvent refining, wax freezing crystallization, and press dewaxing to obtain wax paste, and then solvent deoiling and hydrofining.
With the increasing popularity of scented candles, and the diversification of various candles, events need to be held, the atmosphere needs and incense. The demand for raw materials to make candles is also increasing.
