Choosing the right West System epoxy depends on your project's specific needs. West System offers various formulations designed for different applications. For general bonding and coating, 105 Resin with 205 (fast) or 206 (slow) Hardener provides a strong, moisture-resistant base suitable for most applications. For clear finish projects, 207 Special Clear Hardener mixed with 105 Resin offers excellent clarity and UV-resistance, ideal for visible wood applications. If working in high-temperature environments or needing extra strength, consider 209 Extra Slow Hardener. Always factor in the working temperature and desired working time when selecting your hardener. Additionally, West System's fillers can be added to the epoxy to tailor its properties for specific uses, such as fairing, filleting, or bonding.
Polyethylene glycol (PEG) is recognized as generally safe for use in food and pharmaceuticals by health authorities, including the FDA. Commonly found in laxatives, skin creams, and even processed foods as a thickener or stabilizer, PEG's role in these products is well-documented and regulated. Its safety profile depends on the molecular weight; those used in consumables are designed to be non-toxic and are not absorbed by the body. However, while adverse reactions are rare, individuals with specific sensitivities might experience mild to moderate side effects, such as nausea or diarrhea. As with any additive, it is essential for manufacturers to adhere to recommended usage levels to ensure safety.
When dealing with pigmentation, selecting a toner with ingredients that target hyperpigmentation and evening out skin tone is crucial. Toners containing alpha hydroxy acids (AHAs) like glycolic acid or lactic acid are beneficial as they exfoliate the skin, removing dead skin cells and promoting new cell growth, which can help in fading dark spots. Another powerful ingredient to look out for is vitamin C, known for its brightening properties and ability to diminish the appearance of dark spots. Niacinamide, a form of vitamin B3, can also lighten pigmentation by inhibiting melanin production. Additionally, licorice root extract is a gentle ingredient that can help to brighten the skin and reduce the appearance of pigmentation. Always remember to follow up with a high SPF sunscreen during the day, as the ingredients mentioned can make the skin more sensitive to the sun, and sun exposure can worsen pigmentation.
