  • is oil(not cream based) sunscreen(viscosity like moroccan hair serum) feasible ?

    Posted by arastellar09 on September 28, 2024 at 3:23 am

    there would not be any emulsion. only pure plant oils, oil soluble herb extracts, oil thickener(to stabilise the UV filter dispersion and to avoid filters clumping together), light emollients(as UV filter’s solvents ) and UV filters(carbon-based).

    Will the sunscreen be effective and stable?

    I wanted to put broad spectrum filters like Tinasorb S, Tinasorb M, Mexoryl XL cause they are safest for our body (non-cancerous, non-endocrine disruptors, non-irritants)….but they have many additional ingredients that will most probably give me a lotion rather than transparent oil that I am looking for in my formula. I don’t want to use filters like avobenzone or octocrylene (that are available without additives) but are toxic to us (as per what I found online). So please recommend some oil soluble UV filters (without additives like glycerin, glucoside, gum etc…) that are the least toxic to us and the environment.

    note that the product will be sent for spf testing spf30

    Please, don’t get me wrong, I just to understand something 🤓:

    You’re using as a base exclusively natural oils/extracts, and yet you’re using very synthetic UV filters, so it’s not that you want your formula to be only “natural”.

    Now, you mention that you want “safer” ingredients, but many of the natural oils and extracts you’d use might be sensitizers, comedogenic, etc (at least more than some esters or silicones), especially at the high doses you require. What types of sources of information did you use? Did you check CIR and Cosing? Those are databases where safety studies have been reviewed by the best independent toxicologists in the industry.

      actually I want to make a hair serum (hence comedogenicity is not an issue) with a bit of UV filters cause there is protein degeneration happening under sunlight…I don’t want to make a natural product but it should be non toxic

      plant oils are only going to be around 10-15% rest all light ester and UV solvents.

      Do you have any oil-soluble broad sprecrum filters in mind that I can experiment with?

        As I answered you in another post - drop the idea of DIY SPF product. Unless you have high end equipment to make and test the product you will never be able to reach any reasonable SPF. The danger here you will think it works while it doesn’t.

        Even though the serum goes on hair, some will be in contact with the scalp. 10-15% of natural oils is actually quite a lot, especially if it’s not an emulsion. And if you want something that has less chances to make your skin reactive, esters and silicones are more recommended than natural oils.

        I agree with @fareloz , especially when talking about a body/face sunscreen. You’ll need not only the right equipment but years of knowledge and experience.

    Oil-based sunscreens with light viscosity, similar to Moroccan hair serums, could be feasible but may require frequent reapplication depending on skin type.
