Please can you tell me if the following ingredients are halal:
These are often found in moisturisers and skin care products so would appreciate some clarification please.
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, alcohol derived from dates, grapes, wheat and raisins are not permissible. Alcohol derived from any other sources is permissible for external usage.
Benzyl alcohol is produced naturally by many plants or may even be synthetically manufactured. Therefore benzyl alcohol found in creams and cosmetics is permissible.
Cetyl alcohol in this day and age is derived from palm oil and may also be synthetically produced, hence permissible for external usage. 
Cetearyl, cetostearyl and cetylstearyl alcohol are synonyms. These alcohols are a combination of fatty alcohols, often cetyl and stearyl alcohol make up the major components. Fatty alcohols are commonly derived from vegetable oils. These are also permissible for external usage.

Benzyl alcohol is produced naturally by many plants and is commonly found in fruits and teas.
Name: Benzyl Alcohol
Occurrence and production
Palmitic acid was discovered by Edmond Frémy in 1840, in saponified palm oil. This remains the primary industrial route for its production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water (above 200 °C or 390 °F), and the resulting mixture fractionally distilled to give the pure product.
Palmitic acid is naturally produced by a wide range of other plants and organisms, typically at low levels. It is naturally present in butter, cheese, milk, and meat, as well as cocoa butter, soybean oil, and sunflower oil.
Product Name: Cetostearyl Alcohols
Synonym: Cetearyl Alcohol; Cetylstearyl Alcohol; Mixture of stearyl and cetyl alcohols
