Evobenzone or Butyl methoxydibenzoylmethane is an organic sunscreen or chemical sunscreen that can protect against UVA in the frequency range from 320-390nm, which completely covers UVA I / UVA II.

avobenzone, or Butyl methoxydibenzoylmethane is an organic sunscreen or chemical sunscreen   that can protect against UVA in the frequency range from 320-390nm, which completely covers UVA I / UVA II

The use of Avobenzone in the formulation must not contain Zinc Oxide, Titanium Dioxide and Octyl methoxycinnamate. Because it will cause Avobenzone to deteriorate quickly.

There are several ways to stabilize Avobenzone.

1. Technology AvoTriplex (Copyright: Banana Boat) Avobenzone is mixed with Oxybenzone and Octocrylene In approximately 1:1:2 ratio, for example Avobenzone 3%: Oxybenzone 3%: Octocrylene 6%

2. Technology Helioplex (Copyright: Neutrogena) Avobenzone is mixed with Oxybenzone At approximately 1:2 ratio, for example Avobenzone 3%: Oxybenzone 6%

Additional advice on using Avobenzone in any sunscreen formulation:

1. There should be Disodium EDTA 0.1% in water to help protect Avobenzone from metal ions.

2. Do not contain Alumina or sunscreen containing Alumina (such as some types of Titanium Dioxide).

3. Warm by heating 80-85 degrees to completely dissolve in oil. (Please select any solvent from the information below) for maximum efficiency.

Sun protection table of each type of sunscreen according to UV wavelength

The importance of protecting against both UVA and UVB: UVA causes wrinkles. The aging process of the skin (accelerated skin aging) UVB causes skin burns. Therefore, it is necessary to protect both UVA and UVB at the same time.

Solubility of Avobenzone in various sunscreens and LipidSoft:

This is because Avobenzone comes in powder form. It is necessary to dissolve in these solvents.

Soluble up to 26% in LipidSoft™ Solve (Avobenzone 26% in LipidSoft Solve 74%) Maiden

Up to 24% solubility in Octocrylene ( Avobenzone 24% in Octocrylene 76%)

Up to 21% solubility in Octisalate ( Avobenzone 21% in Octisalate 79%)

Up to 25% solubility in OMC ( Avobenzone 25% in OMC 75%)

Up to 19% solubility in Homosalate ( Avobenzone 19% in Homosalate 81%)

Soluble up to 14% in LipidSoft™ C1215 ( Avobenzone 14% in LipidSoft 86%)

Calculating PA or UVA Protection Performance

Avobenzone 3% or more = PA+++ (8 times more UVA protection)

Avobenzone 2% = PA++ (4 times more UVA protection)

Avobenzone 1% = PA+ (protects twice as much UVA)

FDA rules for the use of Avobenzone in any type of cosmetics

Thailand: not more than 5%

Europe: no more than 5%

USA: no more than 3%

Japan: no more than 10%

(in the case of products for export must follow the FDA regulations of the destination country)
