Description

1 / 24 SUN PROTECTION COMPOSITION

[001] The present invention relates to sunscreen compositions containing bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) and one or more cosmetic oils, characterized in that at least one of the cosmetic oils is isoamyl caprylate. Said compositions exhibit enhanced water repellency (lotus effect).

[002] Sunscreens must be effective and safe. In this sense, sunscreens contain different UVB and UVA filters. Among these UV filters, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is particularly advantageous because it is a broad-spectrum UV absorber, absorbing both UVB and UVA rays, and is highly photostable. Overall, it is currently considered the most effective UV absorber available, considering SPF, based on the maximum concentration allowed by European legislation.

[003] The water repellency of sunscreen products is a fundamental parameter for current sunscreens and can be achieved, for example, by the addition of film-forming polymers. However, these film-forming polymers are not sufficiently effective and / or make the product unattractive to the end consumer due to the resulting sensory properties, since such products often present an oily, opaque and sticky sensation on the skin, as described, for example, in DE 102010063825.

[004] Surprisingly, it has now been discovered that the use of isoamyl caprylate caprate as one of the cosmetic oils present in a sunscreen composition comprising bis-ethylhexyloxyphenol methoxyphenyl triazine significantly improves water repellency (lotus effect) and also enhances the sensory properties of the same.

[005] Thus, in a first embodiment, the present invention provides sun protection compositions comprising Petition 870250082389, dated 12 / 09 / 2025, p. 13 / 40 2 / 24 bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) and one or more cosmetic oils, wherein at least one of the cosmetic oils is isoamyl caprylate.

[006] Another aspect of the invention is directed to the use of isoamyl caprylate caprate to increase the water repellency of a sunscreen composition comprising bisethylhexyloxyphenol methoxyphenyl triazine.

[007] In a further aspect, the invention relates to a method for improving the water repellency of sunscreen compositions, said method comprising the step of preparing a sunscreen composition comprising bisethylhexyloxyphenol methoxyphenyl triazine and isoamyl caprylate caprate, applying said composition to the skin, allowing the volatile constituents to evaporate, thereby forming a hydrophobic film and optionally appreciating the effect.

[008] Without limiting ourselves to theory, it is believed that increased water repellency results in better water resistance of the sunscreen.

[009] Bis-ethylhexyloxyphenol methoxyphenyl triazine (also referred to here as BEMT) is also known as 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (chemical name) or bemotrizinol (INN). BEMT acts as a broad-spectrum UV filter, absorbing UVB and UVA rays. It has two absorption peaks, 310 and 340 nm. BEMT is indicated for use in sunscreens, daily skincare, makeup products such as BB creams, and skin-lightening products.

[010] In all embodiments of the present invention, the amount of BEMT in the sunscreen compositions according to the present invention is advantageously selected in the range of 0.4 to 10% by weight, preferably in the range of 0.4 to 9% by weight, 0.4 to 8% by weight, 0.4 to 7% by weight, 0.4 to 6% by weight, 0.4 to 5% by weight, 0.4 to 4% by weight, 0.4 to 3% by weight, 0.5 to 3% by weight, 0.8 to 9% by weight, 0.8 to 8% by weight, 0.8 to 7% by weight, 0.8 Petition 870250082389, dated 12 / 09 / 2025, page 14 / 40 3 / 24 to 6% by weight, 0.8 to 5% by weight, 0.8 to 4% by weight, 0.8 to 3% by weight, for example in the range of 1 to 5% by weight, 1 to 3% by weight, 2 to 5% by weight, 2 to 4% by weight or 2 to 3% by weight, based on the total weight of the composition.

[095] All sensory evaluations were performed using the emulsions presented in Table 1.

[096] The determination of sensory characteristics was conducted according to a descriptive sensory evaluation process for the parameters described in Table 2 by well-trained tasters. For this, 50 μl of the respective emulsion from Table 1 were applied to a point on the surface of the forearm. After application, the respective emulsion was rubbed until the product was absorbed by the skin. The parameters were evaluated immediately after the rubbing phase. The results are presented in Table 2 below.
