Formula review

WIMJ summary

This product offers a good level of protection against both UVB and UVA rays.

This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

WIMJ summary

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, butylene glycol.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, cetearyl alcohol.

Ingredient	Effectiveness	Concentration	Irritancy
glycerin	HIGH
dimethicone	HIGH
cyclopentasiloxane	MEDIUM

Ingredients by volume

Ingredient	Estimated concentration
water Plain old water	45% - 55%
ethylhexyl methoxycinnamate Octinoxate. When used in higher concentrations, works as a sunscreen protecting the skin from UVB rays. When used in lower concentration, helps to preserve the product formulation. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can be irritating	5.4% - 6.6%
glycerin One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant	4.2% - 5.2%
propylene glycol Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating	3.1% - 3.8%
cyclopentasiloxane A silicone that helps improve the product texture and spreadability. Can absord oil creating a short-term mattifying effect on the skin	2.4% - 3%
phenylbenzimidazole sulfonic acid Ensulizole. A UV filter that is effective against UVB rays. Does not protect against UVA light. It is photostable and can be used to help stabilize other sunscreen ingredients. It is water-soluble meaning that it can help create lighter sunscreen formulations	2.6% - 3.2%
bis-ethylhexyloxyphenol methoxyphenyl triazine Tinosorb S. One of the most effective broad spectrum sunscreen ingredients. Protects from both UVA and UVB rays. It is photostable. Unfortunately, not approved by FDA (US) yet.	2.2% - 2.7%
dicaprylyl carbonate Helps products spread more easily and works as an emollient to soften skin	1.5% - 1.8%
isoamyl p-methoxycinnamate Amiloxate or Neo Heliopan E1000. A UV filter. It is effective against UVB and UVA II rays. Not available in the US	1.7% - 2.1%
potassium cetyl phosphate Helps oil and water mix together	0.95% - 1.15%
alcohol Can be drying and contribute to skin irritation. Used in formulars to dissolve other ingredients, create a thinner product consistency or for its antibacterial properties	0.7% - 1%
dimethicone A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish	0.65% - 0.95%
butylene glycol Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin	0.5% - 0.75%
glyceryl stearate An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together	0.5% - 0.8%
titanium dioxide Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products. Is usually well tolerated by the skin	0.55% - 0.85%
c14-22 alcohols A non-drying alcohol that helps stabilize product formulations	0.45% - 0.65%
polymethyl methacrylate Is used to enhance product texture and can help to optically mask skin imperfections	0.45% - 0.7%
cetearyl alcohol A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture	0.45% - 0.65%
peg-100 stearate Helps oil and water mix togehter and creates a nice product texture	0.45% - 0.65%

c12-20 alkyl glucoside Helps water and oil mix together	0.3% - 0.55%
aluminum hydroxide Is used to add opaque (non-transparent) appearance to formulations. Can be used to coat other ingredients for even dispersion. This is a different ingredient compared to the ones used in antipersperants (aluminium chloride and aluminium chlorohydrate)	0.3% - 0.55%
stearic acid Helps oil and water mix together and works as an emollient	0.45% - 0.65%
