Yes. I found the official/public technical data sheet information for Careclean Eco-Solve. There are two public versions, and the later revision gives a dosage range of 0.5–2% for recirculation, while an earlier PDS gives 1–3% for DPP→CPP cleaning and 0.3–1% for hydrocarbon-free cleaning after mineral oil.
For an RXSOL product page, I recommend using the technical specifications below as a target/comparable specification only, unless your own RXSOL QC/COA confirms these values.

RXSOL ECO-SOLVE is designed for difficult mineral-hydrocarbon contamination, including residues associated with:
Crude and mineral oils
Coal tar
Benzene-containing residues
Lubricating oils
Petroleum distillates
Pyrolysis gas oil
Bitumen
Heavy hydrocarbon deposits
For demanding cargo-tank cleaning, a typical procedure can involve:
Prewash:
Prewash the tank with seawater at approximately 60°C.
Chemical concentration:
DPP → CPP: 1–3%
Hydrocarbon-free cleaning after mineral oil: 0.3–1%
Cleaning temperature:
Approximately 60°C
Circulation time:
Approximately 2–4 hours, depending on contamination and tank condition.
Final step:
Flush thoroughly with suitable water and drain the tank.
The public PDS confirms these application ranges and parameters for the source product.
The referenced product has a reported pH of approximately 7 at 5% dilution in fresh water, making it substantially different from strongly acidic or strongly alkaline tank cleaners.
The reported flash point is above 62°C, which is an important characteristic for marine and industrial cleaning operations.
The product uses an emulsifying cleaning mechanism to assist in loosening and removing heavy hydrocarbon residues and facilitate subsequent flushing.
The product is intended for heavily contaminated systems, including cargo tanks and certain industrial equipment. Marine Care also identifies Eco-Solve for rapid cleaning of challenging mineral-oil cargoes.

Each batch of RXSOL ECO-SOLVE should be released against the approved RXSOL product specification and applicable Certificate of Analysis (COA). Density, pH, appearance and other critical parameters should be verified by the manufacturer's quality-control department before dispatch.

Vegetable oils are divided in:
Vegetable and Animal Oils (Cleaning Procedure)
1. Butterworth the tank with seawater or freshwater with a temperature 20°C. above the melting point of the product to be cleaned. After sufficient pre-cleaning of at least 1.5 hours the temperature can be increased. Drying and Semi-drying ProductsThese are oxidising products and through reaction with oxygen they will dry and harden. Tank cleaning should be executed as soon as possible after discharge. High temperatures (e.g. cleaning or steaming) and heated cargoes in adjacent tanks should be avoided.
2. Butterworth the tank with cold to warm seawater or freshwater.If the product has a higher melting point Butterworth the tank with seawater or freshwater with a temperature maximum 10°C above the melting point of the product. After sufficient pre-cleaning of at least 1.5 - 2 hours the temperature can be increased. Fatty Acids or vegetable/animal oils with high free fatty acid contentsee the cleaning suggestion of Fatty Acids.
3. If seawater was used in step 1 it is of utmost importance to flush/rinse the tank with freshwater before cleaning as per step 3 is continued.
4. (Final cleaning)Prepare the following solution (A) in freshwater (see table):
5. continued Butterworth the tank with the prepared solution for 1, 5-2, 0 hours by recirculation. The necessary temperature can be achieved /maintained by means of heating coil (service tank) cargo heat exchanger or Butterworth heater.If RXSOL-20-2046-210 is used the cleaning temperature should be 60-70°C If Sodium or Potassium Hydroxide is used the cleaning temperature should be 60.C.If RXSOL-20-2046-210 Marine is used the cleaning temperature can be 70-80°C. Depending on the amount of product residues the solution can be used for 1 to 3 tanks.
6. Butterworth the tank 1 hour with hot seawater
7. Rinse the tank with fresh water
8. Inspect the tank; if white residues or a white film is present (calcium/magnesium soaps or carbonate) Butterworth the tank with one the following solution: 3-5% phosphoric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 3-5% nitric acid and 0.4% RXSOL-20-2046-210 (stainless steel only); or 5-10% citric acid and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) or 2% RXSOL-16-1011-025 Marine and 0,4% RXSOL-20-2046-210 (also suitable for Epoxy Coatings) The cleaning temperature should be moderate (50°C.) Use heating coils not the Butterworth heater.
9. Flush the tank with fresh water
10.Ventilate, mop and dry the cargo tank.
Note: for vegetable oils which can be cleaned only by the RXSOL-20-2046-210 (Solution A) the final cleaning can be carried out by recirculation or byinjection (see method 3).
