I'm wondering if one could make a sunscreen without C12-C15 alcohols benzoate, this ingredient seems to be included in all my sunscreens as one of the first 5 ingridients, how much % do you think this makes up? It is quite comedogenic, going by http://www.beautymag...f_cosmetic_.htm
I always feel like my acne gets much worse when using sunscreens, maybe because of the comedogenic ingredients and/or because I can't apply other topicals when I use them. Do you plan to include other benefical ingredients in your sunscreen?
Normally sunscreens feel heavy and make my skin sweaty. Do you know if your sunscreens are better in that regard compared to proprietary forumlations?
I might buy (don't know if you intend to make a profit on this?) your sunscreen if it is superior to the sunscreens I can get in Austria and not too expensive.
One can make a sunscreen without C12-C15 alcohol benzoate. It imparts a dry lubricating feel in the presence of large amounts
of mineral oil or petrolatum. It is also a superior solubizer of lipophilic cosmetic raw materials, also used in parfumes so fragrances last longer. It is versatile and cheap hence it is used in many products.
None of my products contain C12-C15 alcohol benzoate. But the products I make for myself don't have to be cost effective either!
My sunscreen has sprang out from two desires:
1. Lack of good enough sunscreen products on the market that provide sufficient UVA protection without being too whitening.
2. Consistency of existing sunscreens with acceptable UVA protection.
My sunscreens and other products have one thing in common: matte/semi-matte finish after application. No shine! Concentrated activ ingredients that have proven beneficial results for skin with proven anti-aging effect.
Lack of unnecessary ingredients that are usually used for "filling up" the product. Like fragrance, thickeners, unnecessary use of silicon oil, petrolatum (used for moisturizing) etc.
I use pure superior ingredients bought from several Swiss companies that follow "green" production and certified as Swiss quality product.
These include:
Green-tea and white tea extract; an extract that has cell life prolonging activity (backed up by studies and research) and anti-oxidant.
I use humectant that have natural origins like hylaronic acid in much larger quantities than it can be found in products normally (it is 1% or lower, I use 5% and sometimes more).
I use Phytic Acid in high concentration in a delivery system that makes that it is gentle on the skin. It is a chalating anti-oxidant! It is not used in cosmetics (yet).
Pure L-Ascorbic -Acid that is mixed in the product by the costumer so the products efficiency is prolonged. (15 and 20% concentration in a unique delivery system).
Vitamin E and P that have nano-size delivery systems ensuring delivery of the actives in deeper layers of the skin hence preserving their anti-oxidant properties longer and make it more available for skin cells.
I use a combination of many UV filters to ensure proper photo stable long lasting UVA protection.
And yes these products are expensive to produce.
But my mission is that the sunscreens shall be sold for only cost price.
I can state that all these products are superior to all products on the market today (except when it comes to Tretinoin and Hydroquinone of course).
The reason is: the very high concentration of the actives and the unique delivery systems used that ensure much higher penetration.
Lack of fragrance.
