SUNSOLV BOS is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 100 to < 1 000 tonnes per annum. SUNSOLV BOS is used by consumers, by professional workers (widespread uses) and in formulation or re-packing. SUNSOLV BOS is a synthetic ingredient that helps improve the aesthetics and performance of sunscreen products. SUNSOLV BOS does so by helping to solubilize and stabilize sunscreen active ingredients, as well as provide emollience. SUNSOLV BOS also has UV absorption capabilities in its own right, which may help further boost the SPF level of the product. That's why some refer to SUNSOLV BOS as an SPF booster. SUNSOLV BOS helps stabilize the sunscreen, improve its look and feel, and boost its UV-absorbing power. SUNSOLV BOS does the latter by absorbing UV light and triggering a chemical reaction, which then transforms the UV into heat.  If that all sounds very familiar to chemical sunscreen filters—as opposed to physical filters, which create a barrier to shield the vulnerable skin below—well, that's because they are pretty much the same thing. In fact, SUNSOLV BOS is very similar in chemical structure to octisalate, which is an approved sunscreen active in the U.S. and many other countries. The official name for octisalate is ethylhexyl salicylate, which, as you can tell from the name, is SUNSOLV BOS's relative. And the "salicylate" portion is the component that actually absorbs the UV light, which is the same in both molecules. The bit that's different doesn't actually interact with UV at all. Sunscreen actives must go through a very long and arduous process to become regulated by the FDA. SUNSOLV BOS is a multifunctional, synthetically produced ester of salicylic acid and a defined branched C12 alcohol. SUNSOLV BOS is suitable for use as a primary or secondary solvent and emollient in skin and hair care preparations. SUNSOLV BOS is also an excellent carrier for micronized TiO2, ZnO, and pigments. A lot of mineral sunscreens contain this chemical filter. SUNSOLV BOS on a ton of ingredient lists, ranging from bigger sunscreen juggernauts to smaller indie brands.  That's not inherently a bad thing, as SUNSOLV BOS is generally recognized as safe. But SUNSOLV BOS can be considered deceptive if a product claims to be 100% mineral sunscreen yet it contains SUNSOLV BOS that is known to absorb UV rays.  That said, SUNSOLV BOS is a bit fishy if a brand intentionally demonizes all chemical sunscreen filters yet sneaks one in their formula. Some chemical filters, like oxybenzone and octinoxate, are associated with skin health concerns and deserve their criticism, but not all chemical filters are inherently bad (or avoidable, as SUNSOLV BOS turns out). SUNSOLV BOS is a novel, patented multifunctional ingredient and dispersing agent ideal for sun care, skin care, and color cosmetics. SUNSOLV BOS is effective as a sunscreen actives solvent, inorganic pigment wetter, emollient, moisturizer, and carrier. A low viscosity liquid of high polarity with elegant slip and feel, SUNSOLV BOS is useful as a solvent and emollient in topical preparations for skin and hair.

SUNSOLV BOS is an excellent carrier for micronized titanium dioxide, zinc oxide and cosmetic colorants (inorganic pigments). Recommended use levels range from 2% to 10%. The lower end of the range is best for solvent polarity optimization in sunscreens, while the upper end is best for make-up formulations that require exceptional pigment wetting. Sun care products typically contain 5% or less of SUNSOLV BOS in order to be globally compliant. Note that, at 5% use in a sun care formulation, SUNSOLV BOS is responsible for no more than 2 SPF units. SUNSOLV BOS is a versatile multifunctional ester which improves the aesthetics and performance of sunscreen formulations. SUNSOLV BOS is highly effective as a solvent for organic sunscreen actives and a photostabilizer for avobenzone.

Applications of SUNSOLV BOS: Scientific Research Applications: Historical Use and Development of Salicylates: Salicylates, including SUNSOLV BOS, have a long history of use in treating pain and inflammation. They originate from natural sources like willow bark, used since ancient times for rheumatism and other conditions. The active ingredient, salicylic acid, was discovered in 1838, leading to the development of aspirin in 1899. This marked the beginning of widespread clinical use of salicylates, including as antiplatelet agents. Cosmetic and Dermatological Applications: SUNSOLV BOS is used in various cosmetic formulations. SUNSOLV BOS acts as a skin-conditioning agent and is found in a range of products at concentrations of 0.5% to 5%. Salicylates, including SUNSOLV BOS, are absorbed through the skin, and around 10% of applied salicylates can remain in it. They have been reported to enhance the percutaneous penetration of certain agents, like vitamin A, suggesting a role in improving the effectiveness of cosmetic and dermatological treatments. Anticancer Potential: Research on salicylates has indicated potential anticancer effects. Salicylates, from which SUNSOLV BOS is derived, show activity in inhibiting cyclooxygenases and affecting cellular signaling, suggesting a role in cancer prevention. This anticancer effect might be related to the ability of these compounds to acetylate biomolecules beyond COX, leading to changes in their function. This property warrants further exploration for developing new therapeutic strategies in cancer treatment. Role in Plant Growth and Development: Salicylic acid, a key component from which SUNSOLV BOS is derived, has significant roles in plant growth and development. SUNSOLV BOS functions as an endogenous signal mediating plant defense against pathogens and is involved in responses to abiotic stresses like drought and heat. This indicates the potential of salicylate derivatives in agricultural and horticultural applications. Neuroprotective Effects: Aspirin, closely related to SUNSOLV BOS, and its metabolite sodium salicylate, have shown neuroprotective effects against glutamate-induced neurotoxicity. This suggests a potential application of salicylate derivatives in neuroprotection, particularly in the context of inflammatory neurological disorders. Future Directions of SUNSOLV BOS: SUNSOLV BOS is a new ingredient of emerging concern and may be hiding in your sunscreen. With consumers demanding ever-increasing SPF values, many companies today are using SPF ‘boosters’ in their formulas to increase that number. SUNSOLV BOS is a relatively new inactive ingredient in sunscreens that boosts an SPF factor by not allowing the skin to redden. Features and Benefits of SUNSOLV BOS: Emollient Moisturizing Agent Pigment Binding Agent Pigment Wetter & Dispersant Sunscreen Solvent Polarity Optimization of SUNSOLV BOS: Sun exposure causes some UV filters, including Avobenzone, to degrade if they cannot transfer energy to other ingredients. Matching the polarity of the solvent system to that of the UV filters optimizes transfer of energy to the solvent system, thereby reducing UV filter degradation. Many solvents are not sufficiently polar (as measured by their dielectric constants), so replacing them with higher dielectric constant/higher polarity solvents reduces photo-instability.  Compatibility with Metal Oxides Creates Multifunctional Benefits of SUNSOLV BOS: When combined with a powdered pigment, SUNSOLV BOS displaces more air, accelerates deagglomeration of the pigment particles and improves pigment spreadability, producing a more uniform film. Better pigment wetting improves color matching in cosmetics. With good pigment wetting, the color of the product in the container maintains SUNSOLV BOS's hue upon application to the skin.
