Description
Myristic Acid
Myristic Acid is a non-toxic fatty acid that occurs naturally in some animal fats and most vegetables, such as nutmeg, palm and coconut oil. It is used in eye makeup, soaps, detergents, hair care, nail care, shaving and other skin care products.
Myristic acid, also called tetradecanoic acid, is used as a surfactant, emulsifier, cleansing, opacifying & thickening agent in cosmetics products.
Its saponification value is between 243 - 249. It is a white, crystalline, solid. Completely soluble in organic solvents such as ethanol, DMSO, and acetates.
Vegan: Does not contain animal-derived components
Usage
Follow these simple instructions for best results:
Add to oil-phase of formula or in phase with surfactants.
Typical use level 0.5 - 10%. For external use only.
Additional Notes
These are only suggested usage rates. Each formulation is different and you must test in small batches to find the percentages that work best for you. Always start by mixing in a low percentage, then gradually add until you reach your desired result.

Your Description tab currently says this is "partly soluble in water," but the SDS gives a quantified solubility of under 0.13 mg/L at 20°C — that's negligible, not partial. Worth a look before this stays live.
